Chemical substitution in processes for inherently safer design: pros and cons was written by Khan, Easir A.;Syeda, Sultana R.. And the article was included in Pure and Applied Chemistry in 2022.Synthetic Route of C13H10O3 The following contents are mentioned in the article:

The aim of chem. substitution is to replace hazardous chems. with a less hazardous alternative in a certain product or process to make it safer for human health and the environment. While a lot has been done by researchers, industries and regulatory bodies on chem. substitution for safer products, very little has been reported in the field of safer processes. On the other hand, chem. substitution is one of the core principles of inherently safer design, a concept frequently used in the chem. industry for the prevention of major accidents. This work presents an anal. of implementing chem. substitution methodol. for safer processes through inherently safer design. Chem. industries, nowadays, are frequently asked to phase out hazardous chems. from their processes. This paper provides an insight into the issues and practicability of chem. substitution in processes with the help of case studies and a review of the existing frameworks of inherently safer design. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Synthetic Route of C13H10O3).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Synthetic Route of C13H10O3

All-organic polymer blend dielectrics of poly(arylene ether urea) and polyimide: Toward high energy density and high temperature applications was written by Ahmad, Aftab;Tong, Hui;Fan, Tao;Xu, Ju. And the article was included in Journal of Polymer Science (Hoboken, NJ, United States) in 2021.Synthetic Route of C13H10O3 The following contents are mentioned in the article:

The development of high-performance dielec. films with high energy d. and temperature stability is extremely desired for modern electronics and power systems. Herein, a simple and low-cost approach is proposed to fabricate all-organic blend films prepared from poly(arylene ether urea) (PEEU) and polyimide (PI) via solution casting and thermal imidization process. The incorporation of PEEU in PI matrix significantly improved dielec. breakdown strength and dielec. constant of PI. More precisely, blend film with 15 weight% PEEU exhibited highest energy d. 5.14 J/cm3 at 495.65 MV/m, with enhanced dielec. constant of 4.73 and very low dissipation factor of 0.299%. Furthermore, the dielec. properties of the PEEU/PI blend displayed wonderful temperature stability in the range of – 50-+ 250°C, and great frequency stability between 10 and 106 Hz. The blend film also exhibited excellent heat resistance and presented valuable potential in thin film capacitors for high voltage d.c. system. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Synthetic Route of C13H10O3).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

And the article was included in Journal of Applied Polymer Science in 2021.Related Products of 102-09-0 The following contents are mentioned in the article:

A pH-responsive hydrogel consists of polypeptides only is a promising biomaterial with the advantages of good biocompatibility and non-toxicity. This work reports the synthesis of poly-L-ornithine(poc) (polyLOpoc) serving as the precursor for hydrogels of poly-L-ornithine (polyOrn) and poly(L-arginine-r-L-ornithine) (poly(Arg-r-Orn)). Their controllable degree of crosslinking, good mech. properties, good biocompatibility, and pH-responsibility are detailedly investigated. The swelling ratio of polyOrn hydrogel in acidic aqueous solution is 5.7 times higher than that in a basic environment. In the deprotection of phenoxycarbonyl group, polyLOpoc releases amino pendant groups, which attack the remaining poc-protected amino groups to fulfill self-crosslinking without any crosslinking agent. In addition, the pH-responsive behavior of hydrogels is visualized by aggregation-induced emission phenomena with polyOrn and poly(Arg-r-Orn) containing tetrakis(4-aminophenyl)ethene moisture. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Related Products of 102-09-0).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Related Products of 102-09-0

Prediction of Collision Cross Section Values: Application to Non-Intentionally Added Substance Identification in Food Contact Materials was written by Song, Xue-Chao;Dreolin, Nicola;Damiani, Tito;Canellas, Elena;Nerin, Cristina. And the article was included in Journal of Agricultural and Food Chemistry in 2022.Category: esters-buliding-blocks The following contents are mentioned in the article:

The synthetic chems. in food contact materials can migrate into food and endanger human health. In this study, the traveling wave collision cross section in nitrogen values of more than 400 chems. in food contact materials were exptl. derived by traveling wave ion mobility spectrometry. A support vector machine-based collision cross section (CCS) prediction model was developed based on CCS values of food contact chems. and a series of mol. descriptors. More than 92% of protonated and 81% of sodiated adducts showed a relative deviation below 5%. Median relative errors for protonated and sodiated mols. were 1.50 and 1.82%, resp. The model was then applied to the structural annotation of oligomers migrating from polyamide adhesives. The identification confidence of 11 oligomers was improved by the direct comparison of the exptl. data with the predicted CCS values. Finally, the challenges and opportunities of current machine-learning models on CCS prediction were also discussed. 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. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Category: esters-buliding-blocks

Phosgene-free and Chemoselective Synthesis of Novel Polyureas from Activated L-Lysine with Diphenyl Carbonate was written by Yakeya, Daisuke;Yoshida, Yoshiaki;Endo, Takeshi. And the article was included in Macromolecules (Washington, DC, United States) in 2020.SDS of cas: 102-09-0 The following contents are mentioned in the article:

N_α,N_ε-(Phenoxycarbonyl)-L-lysine Me ester 1a can be expected to behave as a difunctional blocked diisocyanate monomer derived from L-lysine with di-Ph carbonate. In this report, we examined a reaction of the obtained compound 1a and 1 equiv of n-butylamine as a model reaction to find that the N_α position of compound 1a reacted selectively with an amine. This means that the reactivity of N_α– and N_ε-phenoxycarbonyl groups is different because the N_α-phenoxycarbonyl moiety has an adjacent ester group. From this result, synthesis of the corresponding polyureas was evaluated by a stepwise reaction of compound 1a with various diamines. The structure anal. and the study of thermal properties of the synthesized polyureas suggested that the carbodiimide moieties were partly constructed in the main chain because of the dehydration triggered by heat treatment of the polyureas. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0SDS of cas: 102-09-0).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.SDS of cas: 102-09-0

And the article was included in ACS Applied Materials & Interfaces in 2021.Recommanded Product: Diphenyl carbonate The following contents are mentioned in the article:

Electrochromic materials have great application in soft displays and devices, but the application of ideal electrochromic textiles still faces challenges owing to the inconvenience of a continuous power supply. Here, electrochromic color-memory microcapsules (ECM-Ms-red, -yellow, and -blue) with a low drive voltage (2.0 V), coloration efficiency (921.6 cm² C^-1), a practical response rate (34.4 s^-1), multistage response discoloration, and good color-memory performance (>72 h) and reversibility (≥1000 cycles) are developed. The color-memory performance is controlled by the energy difference of oxidation-reduction reactions. A multicolor and multistage response electrochromic color-memory wearable smart textile and flexible display are developed that are convenient and energy-efficient for application. The design philosophy of color-memory based on controllable energy difference of reactions has great potential application in sensors and smart textiles.

Organoaluminum hydrides catalyzed hydroboration of carbonates, esters, carboxylic acids, and carbon dioxide was written by Yan, Ben;Dutta, Sayan;Ma, Xiaoli;Ni, Congjian;Koley, Debasis;Yang, Zhi;Roesky, Herbert W.. And the article was included in Dalton Transactions in 2022.Synthetic Route of C13H10O3 The following contents are mentioned in the article:

Reduction of carbonates, carboxylic acids and ester was achieved in reaction with HBpin and [(nacnac)AlH₂] catalyst. The reductive functionalization of the C:O unit of carbonates, carboxylic acids, esters, and CO₂, resp. has received great attention since its introduction. This method is often used industrially for the synthesis of high value-added energy products in chem. This opens up a new way forward to reduce greenhouse gases and the consumption of traditional energy sources. Herein, we report an earth-abundant, cheap, and readily available aluminum dihydride, which can catalyze the reduction of a range of carbonates, esters, carboxylic acids, and CO₂, resp. in the presence of pinacolborane as a reducing agent. Moreover, we demonstrate that the reaction can proceed to obtain good yield products under mild conditions, with low catalyst loading and solvent-free reactions. The mechanism of the catalytic reduction of carbonates has been investigated.

Dynamic analysis and decentralised control system design for diphenyl carbonate reactive distillation process was written by Bandsode, Shirish Prakash;Besta, Chandra Shekar. And the article was included in Indian Chemical Engineer in 2022.Synthetic Route of C13H10O3 The following contents are mentioned in the article:

Reactive distillation (RD), a process intensified technique, involves integrating reaction and separation in a single unit. High non-linearities associated with the RD process constrict the control degrees of freedom and set the key challenge in designing a robust control system. In the present work, the design is optimized for reactive distillation-diphenyl carbonate and a decentralised feedback control configuration is applied to carry out the control studies. A comparative decentralised control performance is studied for different transfer function models obtained by using anal. and optimization-based process identification techniques. The controller parameters obtained from the simple internal model control tuning relations are applied to (i) the linear transfer function model and (ii) non-linear plant model. Set-point tracking and load rejection studies are carried out to compare the performance of different models and investigate the non-linear model’s controller performance. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Synthetic Route of C13H10O3).

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. 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.Synthetic Route of C13H10O3

Well-defined, environment-friendly synthesis of polypeptides based on phosgene-free transformation of amino acids into urethane derivatives and their applications was written by Endo, Takeshi;Sudo, Atsushi. And the article was included in Polymer International in 2020.HPLC of Formula: 102-09-0 The following contents are mentioned in the article:

A review. In this study, both naturally occurring and artificial amino acids were successfully transformed into the corresponding urethane derivatives using di-Ph carbonate. The urethanes thus prepared could be efficiently cyclized into amino acid N-carboxyanhydrides (NCAs) without the requirement of phosgene. In addition, the presence of primary amines converted the urethane derivatives into NCAs and initiated the ring-opening polymerization of the in situ formed NCAs, allowing for the well-defined synthesis of polypeptides. These polypeptides contained initiating ends functionalized by an amine-derived residue and propagating ends bearing the reactive amino group. By precise control of the structures of the polypeptides, various polypeptide conjugates such as block copolymers and graft copolymers were successfully synthesized as designed, and their applications in antifouling coatings against proteins, drug delivery systems and biosensors were demonstrated. © 2019 Society of Chem.

It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. 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.HPLC of Formula: 102-09-0
