Organic luminogens have extensive applications due to their unique photophys. properties. In recent years, nonconjugated organic luminogens, in contrast to traditional conjugated luminogens, have gained much attention because of their facile preparation, environmental friendliness, and biocompatibility. In this study, a new kind of nonconventional luminogen based on dynamic covalent cross-linked polyhydroxyurethane is reported for the first time. The new luminogen not only exhibits intrinsic strong fluorescent emission in the solid state but also possesses high mech. properties along with good shape memory and self-healing properties. In addition, the new luminogens are synthesized from aliphatic polyfunctional cyclic carbonate and amines via a much more straightforward method, avoiding the use of toxic isocyanates. Investigations indicated that the intrinsic luminescence of the resultant luminogens was induced by the crosslinking of polymer chains and could be well tuned by controlling the degree of crosslinking. By taking advantage of the unique characteristics of the resultant polymer luminogens, we further developed a facile method, named “light-mediated ink-free screen printing”, for anticounterfeiting paper fabrication. Different from traditional ink-based printing technol., the new method used UV-light instead of expensive security ink to encode anticounterfeiting information on natural cellulose paper. The anticounterfeiting information is stable under various wet conditions, showing promising applications in the fast-growing counterfeiting of pharmaceuticals, packaging, and the food industry. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Category: esters-buliding-blocks).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Category: esters-buliding-blocks

In the present study nanotechnol. approach, i.e., a cyclodextrin (CD) based carbonate nanosponge was used to improve the solubility and dissolution of ibuprofen. Solvent and ultrasound assisted methods were used to prepare nanosponges using two CDs (β-CD and 2-hydroxypropyl-β-CD (2HP-β-CD)) and a cross-linker (CL) di-Ph carbonate (DPC) in varying molar ratios. Nanosponges were investigated for their solubilizing efficiency and phase solubility studies. Structural anal. by Fourier transform IR (FTIR) and powder X-ray diffraction (PXRD), thermo-anal. characterization by differential scanning calorimetry (DCS), morphol. by SEM (SEM). In-vitro drug release followed by in-vivo analgesic and anti-inflammatory studies were performed. 2HP-β-CD based nanosponges (molar ratio 0.01:0.04) prepared by ultrasound assisted method showed the highest solubilizing efficiency (i.e., 4.28 folds). Stability constant values showed that all complexes were stable. Inclusion complexes of drug was confirmed by PXRD and DSC. SEM images showed porous structures confirming the formation of cross-linked network. Particle size was in the range of 296.8 ± 64 to 611.7 ± 32nm. In-vitro release studies showed enhanced dissolution profile from nanosponge formulation (~94% from I11) as compared to the pure drug (~45% Ibuprofen) in 120min. Significant (p<0.05) extent of pain inhibition and anti-inflammatory activity was observed for nanosponge formulation when compared with the pure drug. CD based carbonate nanosponges with better solubility, enhanced release profile, improved analgesic and anti-inflammatory activity were successfully formulated for ibuprofen. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Recommanded Product: Diphenyl carbonate).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Recommanded Product: Diphenyl carbonate

Alkaline Soil Degradation and Crop Safety of 5-Substituted Chlorsulfuron Derivatives was written by Wu, Lei;Hua, Xue-Wen;Li, Yong-Hong;Wang, Zhong-Wen;Zhou, Sha;Li, Zheng-Ming. And the article was included in Molecules in 2022.Formula: C13H10O3 The following contents are mentioned in the article:

Sulfonylurea herbicides can lead to serious weed resistance due to their long degradation times and large-scale applications. This is especially true for chlorsulfuron, a widely used acetolactate synthase inhibitor used around the world. Its persistence in soil often affects the growth of crop seedlings in the following crop rotation, and leads to serious environmental pollution all over the world. Our research goal is to obtain chlorsulfuron-derived herbicides with high herbicidal activities, fast degradation times, as well as good crop safety. On account of the slow natural degradation of chlorsulfuron in alk. soil, based on the previously reported results in acidic soil, the degradation behaviors of 5-substituted chlorsulfuron analogs (L101-L107) were investigated in a soil with pH 8.39. The exptl. data indicated that 5-substituted chlorsulfuron compounds could accelerate degradation rates in alk. soil, and thus, highlighted the potential for rational controllable degradation in soil. The degradation rates of these chlorsulfuron derivatives were accelerated by 1.84-77.22-fold, compared to chlorsulfuron, and exhibited excellent crop safety in wheat and corn (through pre-emergence treatment). In combination with bioassay activities, acidic and alk. soil degradation, and crop safety, it was concluded that compounds L104 and L107, with Et or Me groups, are potential green sulfonylurea herbicides for pre-emergence treatment on wheat and corn. This paper provides a reference for the further design of new sulfonylurea herbicides with high herbicidal activity, fast, controllable degradation rates, and high crop safety. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Formula: C13H10O3).

Preparation and Degradation of Waste Polycarbonate-Derived Epoxy Thermosets and Composites was written by Yeh, Ren-Yu;Reddy, Kamani Sudhir K.;Chen, Yi-Chun;Wang, Meng-Wei;Chang, Hou-Chien;Abu-Omar, Mahdi M.;Lin, Ching Hsuan. And the article was included in ACS Applied Polymer Materials in 2022.Application of 102-09-0 The following contents are mentioned in the article:

We report a robust, 100% atom-efficiency strategy for preparing waste polycarbonate (WPC)-derived epoxy resin. To demonstrate the preparation process, we perform a pyridine-catalyzed model reaction between di-Ph carbonate (DPC) and diglycidyl ether of bisphenol A (DGEBA) in a molar ratio of 1:2. After epoxy-equivalent titration and two-dimensional NMR (2D-NMR) anal., we confirm that the product is bis(1-(4-(2-(4-(oxiran-2-ylmethoxy)phenyl)propan-2-yl)phenoxy)-3-phenoxypropan-2-yl) carbonate (DPC-EP2). Based on the model reaction, three WPC-based epoxy resins (WPC-EPX, X = 2, 3, and 4) were prepared by the reaction of WPC with DGEBA in a molar ratio of 1:2, 1:3, and 1:4 in the presence of pyridine. The WPC-EPX epoxy resins were cured with WPC, phenol novolac (PN), diamino diphenylmethane (DDM), and dicyandiamide (DICY). The mech. and thermal properties of the thermosets were discussed. We also prepared epoxy/carbon fiber composites and investigated the degradation of epoxy thermosets and the recycling of the carbon fiber. When the WPC-EP2 epoxy resin was cured with WPC, it can be successfully degraded to a phenoxy resin and 1,3-dihyexylurea through a catalyst-free aminolysis process. Undamaged carbon fibers have been recycled, according to the SEM-energy-dispersive x-ray spectroscopy (SEM-EDS) and tensile stress-strain data. The transformation of WPC to WPC-EPX, the aminolysis of WPC-EP2/WPC to a phenoxy resin and 1,3-dihexylurea, and the recycling of carbon fiber in the composite have been successfully demonstrated. Therefore, we believe that this work contributes greatly to the field of “sustainable approaches in waste utilization.”.

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Application of 102-09-0

Introducing biobased polymers from renewable sources for use as high-performance thermoplastics with high demands on mech. rigidity, transparency, thermal stability, as well as good processability, is a significant challenge. In the present work we have designed and prepared a rigid biobased bis-spirocylic diol by di-cycloketalization of a bicyclic diketone (cis-bicyclo[3.3.0]octane-3,7-dione, obtained from citric acid) using trimethylolpropane. This spiro-diol monomer has two reactive primary hydroxyl groups and the synthesis from inexpensive biobased starting materials is straightforward and readily upscalable, involving no chromatog. purification In order to explore the usefulness of the new monomer, it was employed in melt polycondensations with diphenylcarbonate at up to 280°C to form rigid fully amorphous polycarbonates (PCs). Mol. weights (MWs) up to Mn = 28 kg mol^-1 were achieved, and thermal and dynamic mech. measurements showed glass transitions up to T_g = 100°C, with no thermal decomposition until T_d ∼350°C. Solvent cast films had excellent mech. flexibility and strength, as well as a high transparency with only slight coloration. Results by dynamic melt rheol. implied that the high-MW PCs had a good processability at 170°C, with a stable shear modulus over time, but started to degrade via chain scission reactions when the temperature approached 200°C. In conclusion, the present work demonstrates the straightforward preparation of the citric acid-based spiro-diol, and indicates that it is an efficient building block for the preparation of rigid biobased PCs and other condensation polymers.

Formulation and modification of physicochemical parameters of p-Coumaric acid by cyclodextrin nanosponges was written by Kumar, Anil;Rao, Rekha. And the article was included in Journal of Inclusion Phenomena and Macrocyclic Chemistry in 2022.Application In Synthesis of Diphenyl carbonate The following contents are mentioned in the article:

Reactive oxygen species triggered oxidative stress contributes to the pathogenesis of numerous ailments such as myocardial infraction, inflammation, atherosclerosis, and pigmentation disorders. ROS scavengers, particularly natural bioactives are one of the possible options to reduce this stress. However, these bioactives possess certain formulation challenges owing to their poor solubility, stability, and bioavailability. Therefore, the design of a stable formulation that can deal these challenges, while preserving the antioxidant efficacy is of great significance. In this view, the current study was aimed at fabrication of p-Coumaric acid loaded nanosponges employing melt method. The spectroscopy resulting nanosponges were appropriately characterized using Fourier transform IR spectroscopy, X-ray powder diffraction, differential scanning calorimetry, thermogravimetric anal., NMR, FE-SEM (field emission SEM) and TEM (transmission electron microscopy). The particle size of PCA-CDNS (p-Coumaric acid nanosponges) was in nano range, with low PDI (polydispersity index), acceptable zeta potential and delayed release. Mol. docking studies for PCA using mushroom tyrosinase (TYR) were also carried out. Further, the antioxidant and antityrosinase studies were also performed. In nutshell, the findings herein revealed that encasement of PCA in NS led to an enhancement in efficacy of this bioactive in terms of safety, solubility, and release, while preserving its antioxidant and antityrosinase effects. On the basis of the present results, we expect that PCA nanosponges can be seen as promising carriers for addressing depigmention, particularly associated with ROS overexpression.

Full atom-efficiency transformation of wasted polycarbonates into epoxy thermosets and the catalyst-free degradation of the thermosets for environmental sustainability was written by Shao, Shih Wei;Chen, Chien Han;Chan, Jian Ren;Juang, Tzong Yuan;Abu-Omar, Mahdi M.;Lin, Ching Hsuan. And the article was included in Green Chemistry in 2020.Formula: C13H10O3 The following contents are mentioned in the article:

We report two sustainable features in this work. The first feature is that we successfully applied wasted polycarbonate (WPC) as an epoxy curing agent for epoxy resins to prepare WPC-cured epoxy thermosets. The curing of WPC and epoxy is based on the reaction of a carbonate and an epoxide, which is proven by a model reaction of di-Ph carbonate (DPC) and glycidyl Ph ether (GPE) in the presence of a catalytic amount of 4-dimethylaminopyridine (DMAP). The WPC-cured epoxy thermosets show comparable thermal properties to com.-based, phenol novolac (PN)-cured epoxy thermosets. Interestingly, the films of WPC-cured epoxy thermosets are foldable, while those of PN-cured epoxy thermosets are brittle, demonstrating the advantage of using WPC as a curing agent over PN. Since the WPC was used directly without any digestion or pyrolysis process, the at. efficiency is 100%, making this WPC recycling strategy economically attractive. The second feature is that we successfully degraded the WPC-cured epoxy thermosets to phenoxy resins through a catalyst-free aminolysis process, i.e., the products based on the WPC-cured epoxy thermosets are degradable when their lifespans are expired. The transformation of WPC into epoxy thermosets, along with the degradation of the epoxy thermosets, makes this work attractive for sustainability. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Formula: C13H10O3).

Diphenyl carbonate (cas: 102-09-0) belongs to esters.

Mitigation of bromine-containing products during pyrolysis of polycarbonate-based tetrabromobisphenol A in the presence of copper(I) oxide was written by Oleszek, Sylwia;Kumagai, Shogo;Grabda, Mariusz;Shiota, Kenji;Yoshioka, Toshiaki;Takaoka, Masaki. And the article was included in Journal of Hazardous Materials in 2021.Application In Synthesis of Diphenyl carbonate The following contents are mentioned in the article:

Polycarbonate (PC) is an engineering thermoplastic that is widely used in elec. and electronic equipment. This plastic often contains tetrabromobisphenol A (TBBA), the most common brominated flame retardant. Thermal degradation of the PC-TBBA leads to generation of numerous bromo-organic products in the pyrolytic oil, hindering its appropriate utilization, as well as corrosive hydrogen bromide gas. The purpose of this study was to exptl. investigate and compare the pyrolysis products of PC-TBBA and PC-TBBA + Cu₂O at various temperatures, with an emphasis on the yield and distribution of brominated compounds In pyrolysis of PC-TBBA + Cu₂O, at the maximum degradation temperature (600 °C), as much as 86% of total Br was trapped in the residue, while 3% and 11% were distributed in the condensate and gas fractions, resp. In contrast, the distribution of Br from non-catalytic pyrolysis of PC-TBBA (600 °C) was 0.5% residue, 40% condensate, and 60% gas. The results of this study revealed that in the presence of Cu₂O, organo-bromine products were most likely involved in Ullman-type coupling reactions, leading to early crosslinking of the polymer network that efficiently hinders their vaporization. HBr in the gas fraction was suppressed due to effective fixation of bromine in residue in the form of CuBr. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Application In Synthesis of Diphenyl carbonate).

Synthesis of reprocessable lignin-based non-isocyanate poly(imine-hydroxyurethane)s networks was written by Xue, Danwei;Xue, Bailiang;Tang, Rui;Shen, Chao;Li, Xinping;Zhao, Wei.

In this study, an environmentally friendly and non-toxic route to synthesize lignin-based non-isocyanate poly(imine-hydroxyurethane)s networks was explored. Specifically, the NH₂-terminated polyhydroxyurethanes (NPHUs) prepolymer was first synthesized from bis(6-membered cyclic carbonate) (BCC) and diamine via the ring-opening reaction. Subsequently, the corresponding lignin based non-isocyanate polyurethanes (NIPUs) with tunable properties were synthesized from NPHUs and levulinate lignin derivatives containing ketone groups via the Schiff base reaction. The structural, mech., and thermal properties of NIPUs with different stoichiometric feed ratios of BCC and levulinate lignin were characterized by Fourier transform IR spectroscopy, NMR, differential scanning calorimetry, dynamic mech. anal., and thermogravimetric anal.. The results indicated that the tensile strength, Young’s modulus, toughness, storage modulus, glass transition temperature, and thermal stability of lignin-based NIPUs gradually increased with increasing lignin content, and the highest Young’s modulus of 41.1 MPa was obtained when lignin content reached 45.53%. With good reprocessing properties, this synthetic framework of lignin-based NIPUs also provides sustainable non-isocyanate-based substitutions to traditional polyurethane networks.

Hybrid heat-integrated design and control for a diphenyl carbonate reactive distillation process was written by Lee, Hao-Yeh;Novita, Felicia Januarlia;Weng, Kuo-Chun. And the article was included in Chemical Engineering and Processing in 2021.Application of 102-09-0 The following contents are mentioned in the article:

This study proposed the design and control system of a hybrid heat-integrated configuration for the di-Ph carbonate (DPC) indirect reactive distillation (RD) process. First, an existing DPC production process with an RD column and a distillation column (C1) as the base case was modified and optimized for further evaluation. Both thermally coupled distillation (TCD) and double-effect (DE) configurations were examined to simultaneously improve the energy efficiency. A hybrid heat-integrated configuration for the DPC indirect RD process was finally proposed. The remixing effect at the top part of the RD column could be removed, and the energy wastage in the condenser of the C1 was lower than that in the TCD configuration. The heat exchanger (HE) area was smaller than that in the DE configuration. Among all configurations, the hybrid configuration was superior; around 34.0% of energy could be saved for producing 99.5 mol% of DPC. Then, three control structures (CS1, CS2, and CS3) and two inventory control loops (inventories A and B) were proposed in the hybrid heat-integrated configuration. Pressure-compensated temperature (PCT) control was also applied to eliminate the effect of pressure floating. The dynamic simulation results revealed that the CS3 PCT could maintain specifications during throughput and composition disturbances. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Application of 102-09-0).
