M.. And the article was included in Surface and Interface Analysis in 2022.Synthetic Route of C73H108O12 This article mentions the following:

Reflection electron energy loss spectroscopy (REELS) spectra were measured for seven insulating organic compounds (DNA, Irganox 1010, Kapton, polyethylene [PE], poly(Me methacrylate) [PMMA], polystyrene [PS] and polytetrafluoroethylene [PTFE]). Optical constants and energy band gaps were extracted from the measured REELS spectra after elimination of multiple electron scattering via a deconvolution and fitting the normalized single scattering energy loss spectra to Drude and Drude-Lindhard model dielec. functions, constrained by the Kramers-Kronig sum and f-sum rules. Satisfactory agreement is found for those optical constants for which literature data exists. For PTFE, the observed features in the optical data correspond to its electronic structure. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Synthetic Route of C73H108O12).

The migration of NIAS from ethylene-vinyl acetate corks and their identification using gas chromatography mass spectrometry and liquid chromatography ion mobility quadrupole time-of-flight mass spectrometry was written by Vera, Paula;Canellas, Elena;Nerin, Cristina;Dreolin, Nicola;Goshawk, Jeff. And the article was included in Food Chemistry in 2022.Category: esters-buliding-blocks This article mentions the following:

An exhaustive migration study of eight corks, made of ethylene-vinyl acetate, was carried out to identify any non-volatile and volatile compounds using an untargeted approach. The challenge associated with the structural elucidation of unknowns was undertaken using both ultra-high-performance liquid chromatog. coupled to an ion-mobility separation quadrupole-time of flight mass spectrometer and gas chromatog. mass spectrometry. A total of fifty compounds were observed to migrate from the corks, and among these additives such as antioxidants (Bu 4-hydroxybenzoate, Irganox 1010, Irganox 1075, Irgafos 168 and BHT) or lubricants (EBO and octadecanamide, N,N-1,2-ethanediylbis-) were identified. A high proportion (84%) of the detected compounds was non-intentionally added substances (NIAS), and included several cyclic oligomers with different chain sequences. NIAS, such as 2,6-bis(1,1-dimethylethyl)-4-Et and 7,9-ditert-butyl-1-oxaspiro[4.5]deca-6,9-diene-2,8-dione, break-down products, including hexa-, hepta- and nonadecanamide, N,N-1,2-ethanediylbis-, and oxidation products were also identified. One cork was found to be unsuitable for use as a food contact material. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Category: esters-buliding-blocks).

Cross-linked charring strategy for mitigating hazards of smoke and heat of aluminum diethylphosphonate/polyamide 6 by caged octaphenyl polyhedral oligomeric silsesquioxanes was written by Feng, Haisheng;Li, Dinghua;Cheng, Bo;Song, Tinglu;Yang, Rongjie. And the article was included in Journal of Hazardous Materials in 2022.Safety of 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) This article mentions the following:

Aluminum diethylphosphonate (ADP) is a highly efficient phosphorus-based flame retardant, widely used in polyamide 6 (PA6). However, ADP/PA6 releases large amounts of heat and smoke under high heat flux, which commonly means serious hazards to life and property. Octaphenyl polyhedral oligomeric silsesquioxanes (OPS) is an organic-inorganic hybrid silicon compound, playing flame retardant role in condensed phase. In this work, combustion behaviors of OPS/ADP/PA6 were investigated by limited oxygen index (LOI), UL94 and cone calorimeter (CONE) tests. The LOI and UL94 rating results did not change obviously, while the CONE data and smoke d. data showed the synergistic effect of OPS and ADP in PA6. For 2.5%OPS/7.5%ADP/PA6, the peak values of heat, smoke and CO release rate (pk-HRR, pk-RSR, Ds, max with/without pilot flame and pk-COP) decreased by 60.2%, 82.1%, 45.9%/38.3% and 80.4% resp., compared with 10%ADP/PA6. Moreover, 2.5%OPS/7.5%ADP/PA6 produced 337.5% more residue than 10%ADP/PA6. TGA, TG-IR, SEM-EDS, XPS and py-GC/MS were used to further explore the synergistic mechanism of OPS and ADP. It was verified that the cross-linked charring strategy apparently has weakened the hazards of smoke and heat of PA6. This work proposed a possible tech. approach to solve both fire risk and heat/smoke hazards of PA6. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Safety of 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate)).

Effect of the elastomer viscosity on the morphology and impact behavior of injection molded foams based on blends of polypropylene and polyolefin elastomers was written by Munoz-Pascual, Santiago;Saiz-Arroyo, Cristina;Vananroye, Anja;Moldenaers, Paula;Rodriguez-Perez, Miguel Angel. And the article was included in Journal of Applied Polymer Science in 2021.Computed Properties of C73H108O12 This article mentions the following:

The impact resistance of injection-molded polypropylene (PP) parts is severely reduced when they are foamed. It is necessary to implement strategies, such as elastomer toughening, to increase the impact behavior of foamed parts. However, the knowledge on the effect of elastomer addition on the morphol., cellular structure, and impact of injection-molded cellular parts is very limited. In this work, foamed parts based on blends of PP and polyolefin elastomers have been produced and characterized. A high and a low viscosity octene-ethylene copolymer (EOC) and a high viscosity butene-ethylene copolymer (EBC) were employed. The blends have been thermally and rheol. characterized. Solids materials and foams (relative d. 0.76) were injection-molded. The solid phase and cellular structure morphologies were studied using SEM. The results showed that elastomer toughening has been successful to obtain an improvement of the impact behavior in solid and cellular polymers. In this case, EOC materials provide an appropriate interfacial adhesion and optimized cellular structure which results in high impact resistance. The optimum elastomer to improve the properties is the EOC with a higher viscosity which provides impact resistance with n values below 3 due to the toughening of polymer matrix, thick skin thickness, and low cell size. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Computed Properties of C73H108O12).

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.Computed Properties of C73H108O12

Migration testing of metallized polypropylene films treated with ionizing radiation was written by Zhang, Hong;Wang, Yini;Wu, Jingjie;Zhu, Lei;Xia, Yining. And the article was included in Food Packaging and Shelf Life in 2022.Application of 6683-19-8 This article mentions the following:

An UHPLC-QTOF/MS method was employed to identify chems. migrating from metalized polypropylene (met PP) films. The migration test was conducted by converting met PP films into pouches filled with 95% ethanol as a fatty food simulant and treating the pouch samples with gamma and electron beam irradiation at a dose of 10 kGy. A temperature of 22°C and a duration time of 21 days were used for the migration test. Over 10 chems. were identified, 3 of them were intentionally added substances (IAS), while the rest were considered as non-intentionally added substances (NIAS) including radiolysis products (RPs) derived from antioxidants. Based on the identification results, 5 chems. (3 hindered phenolic compounds, 1 phosphate compound and 1 phosphonate compound) were selected and their migration behaviors were evaluated under the effect of irradiation It was found that irradiation treatment significantly reduced the migration level of all substances. The extent of decrease was dependent on their stability under irradiation The phosphate/phosphonate compounds recorded higher stability resulting in less decrease (3-25%) in migration level. The hindered phenolic compounds were susceptible to irradiation and a large drop (45-88%) of migration level was observed Potential risks of met PP films were evaluated by comparing the migration levels of selected chems. with their migration limits either listed in Regulation (EU) Number 10/2011 or established with Cramer classification. The results showed that the migration level of the phosphonate compound was above the recommended migration limit, which may present a safety concern. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Application of 6683-19-8).

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.Application of 6683-19-8

And the article was included in Journal of Applied Polymer Science in 2022.Product Details of 6683-19-8 This article mentions the following:

In this work, we confirmed that the major sort of impurity in waste polyethylene (PE) packing films is calcium carbonate. Consequently, PE/poly(ethylene-co-1-octene)-maleic anhydride (rPE/POE-g-MAH) and poly(ethylene-co-1-octene) (rPE/POE) composites were recycled using a custom-made three-screw extruder, who can supply intensive shear flow during extrusion. The POE-g-MAH is detected to be filled between PE and inorganic impurities, and the compatibility is improved through chem. reactions. As mech. test manifested, the rPE/POE-g-MAH blends present higher tensile strength and elongation at break than the rPE/POE blends at the same composition The reason for such improved toughness of composite was explained in detail through the tensile fracture surface anal. Rheol. test further shows that POE-g-MAH improves the compatibility of matrix and impurities.

Effects of zinc isophthalate on the crystallization and crystal transformation behavior of polybutene alloy was written by Zhu, Enci;Guo, Chao;Wang, Jie;Zhao, Shicheng. And the article was included in Journal of Polymer Research in 2022.Formula: C73H108O12 This article mentions the following:

The slow crystallization rate and crystal transformation restrict the application of PB-A (PB blended with 2-3wt% polypropylene). This paper investigated the effects of zinc isophthalate (ZnIA) on the crystallization and crystal transformation behavior of PB-A by means of DSC, POM, XRD and Flash DSC. The results showed that addition of ZnIA raised the crystallization peak temperature from 71.1°C to 82.8°C and decreased the half crystallization time from 818 s to 160 s at the content of 0.2wt%. It also reduced the spherulites size dramatically according to the images of POM. The survey conducted by Flash DSC showed that the formation of amorphous phase was retarded by the addition of ZnIA as cooling rate increasing and as a result, the crystallinity of PB-A was raised from 50.0 to 56.1% with 0.2wt% ZnIA added. Moreover, the improvement on crystal transformation caused by ZnIA could be owing to the increase in crystallization temperature which leads to the enhancement of internal thermal stress and shortened nucleating process as well before the growth of form I. In conclusion, Znic Isophthalate is a kind of effective and multifunctional nucleating agent for PB-A and this study is beneficial to understand the mechanism of crystallization as well as the crystal transformation for PB-A. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Formula: C73H108O12).

Effect of polypropylene molecular weight distribution on the balance between the toughness and rigidity of the impact polypropylene composites was written by Li, Fushi;Gao, Yunbao;Yan, Nan;Zhang, Chunyu;Zhang, Xuequan;Jiang, Wei. And the article was included in Journal of Applied Polymer Science in 2022.Related Products of 6683-19-8 This article mentions the following:

In this study, homo-polypropylene (HPP) with the same number average mol. weight (M n) while different mol. weight distribution (MWD) are directly melt blended with a polyolefin elastomer (POE) in order to study the effects of the MWD of HPP on the brittle-ductile transition (BDT) and the balance between toughness and rigidity of the PP/POE composites. The results show that for the same number average mol. weight HPP, the wider the MWD, the higher the brittle strength σ_b of the HPP is, and the larger the critical interparticle distance (ID_c) of the composite is. Larger ID_c means lower modifier content can induce the BDT, and thereby leads to less modulus loss of the composites. Namely, the toughened HPP with wider MWD can have a better balance between toughness and rigidity. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Related Products of 6683-19-8).

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.Related Products of 6683-19-8

Morphology evolution and mechanical property enhancement of linear low-density polyethylene by adding disentangled ultrahigh molecular weight polyethylene was written by Zhang, Yu;Di, Yutao;Ye, Chunlin;Zhang, Letian;Tang, Xin;Shu, Baoqiang;Yan, Xiang;Li, Wei;Wang, Jingdai;Yang, Yongrong. And the article was included in Polymers for Advanced Technologies in 2022.Application of 6683-19-8 This article mentions the following:

Ultra-high mol. weight polyethylene (UHMWPE) and linear low-d. polyethylene (LLDPE) with different ratios were melt-blended in an internal mixer. Results of rheol. tests and SEM indicate that the blends are well miscible in the range of small addition amount of UHMWPE. The content of UHMWPE is suggested to be less than 5.0 wt%, to guarantee good compatibility of biphasic blends. Differential scanning calorimetry studies indicate that co-crystallization occurs between UHMWPE and LLDPE. The crystallinity increases with the increase of UHMWPE as a nucleating agent. As a result, an improvement in mech. properties is achieved. When the addition amount of UHMWPE is 5.0 wt%, the impact strength, breaking elongation, Young’s modulus, and tensile strength are significantly increased by 27%, 25%, 75%, and 21% resp.

In the past few decades, considerable attention has been paid to the thermoplastic elastomer (TPE). Among them, hydrogenated styrenic block copolymers (HSBCs) have attracted extensive interest because of outstanding ozone resistance, remarkable aging properties, and environmental friendliness. Therefore, theor. and exptl. investigations on the HSBCs/PP/oil composites have been reported many times, but the influence of mol. structure on the structure and properties of composites has yet to be identified. In this study, three HSBCs with different mol. structures were used as the research object to systematically study the effects of their mol. structural differences on the aggregate structure, microstructural, mech., and thermal properties of HSBCs/PP/oil composites. It was found thatthe content of side groups in the mol. chain was the main factor affecting the structure and performance of the HSBCs/PP/oil composites. This research can provide theor. guidance for the mol. design and structural control of the new HSBC, so it has obvious theor. significance and practical value. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Recommanded Product: 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate)).

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. 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.
