Absorbent selection based on the COSMO-RS method for carbon capture in integrated gasification combined cycle plant was written by Li, Yun;Huang, Weijia;Zheng, Danxing;Mi, Yue. And the article was included in Beijing Huagong Daxue Xuebao, Ziran Kexueban in 2014.Application In Synthesis of Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:

Around 150 commonly used industrial solvents, with and without N atoms in their mols., have been compared as absorbents at T=298.15 K for carbon capture in IGCC plants according to the feed gas characteristics. Henry’s constants of the CO₂+absorbent systems were calculated using the COSMO-RS software. It was found that the amount of CO₂ absorbed decreased with the increasing number of hydroxyl groups in the absorbent mol. Absorbents having ether, ketone or ester groups showed excellent absorption behavior for CO₂. However, acids, alcs. and alkanes showed the worst dissolving ability for CO₂. The isothermal synthesis method was employed for the determination of CO₂ solubility in four selected absorbents with ether and ester groups at T=298.15 K and pressures up to 1.3 MPa. In addition, Henry’s constants of the above systems were calculated It was found that the exptl. data showed good agreement with the predicted values. It was found that diethylene glycol monoethyl ether acetate (carbitol acetate) was the best absorbent for CO₂ and this material should be studied further for use in carbon capture in an integrated gasification combined cycle (IGCC) plant. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Application In Synthesis of Ethyl 3-ethoxypropanoate).

Ethyl 3-ethoxypropanoate (cas: 763-69-9) 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. 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.Application In Synthesis of Ethyl 3-ethoxypropanoate

Recent advances in aliphatic moisture cure urethane coatings was written by Squiller, Edward P.;Best, Kurt. And the article was included in PMSE Preprints in 2010.Name: Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:

To apply a defect free polyurethane moisture cure coating, requires the consideration of several factors: choice of nonfunctional thermoplastic acrylic resin, solvents, catalyst level and applied % NCO content. And within these factors there is a synergy that incrementally builds to make a more robust defect free polyurethane moisture cure coating at increased film thicknesses. The central characteristic when considering these factors ultimately relates back to speed of cure. Since the evolution of CO2 in the curing process of polyurethane moistures cure is inevitable, the coating must be formulated to retain its flow and leveling as long as possible while still resulting in overnight cure. This is accomplished by choosing an acrylic grinding resin with a high acid number and lower mol. weight This resin helps de-water the pigments and additives used in moisture cure formulation. The final steps in formulating a defect free moisture cure polyurethane coating are to use low levels of catalyst and a low applied % NCO prepolymer. These factors, combined in this manner result in a moisture cure coating that is applied at thicknesses that are double the current state of the art in aliphatic moisture cure coatings on the market today. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Name: Ethyl 3-ethoxypropanoate).

Cultivable microbial ecology and aromatic profile of “mothers” for Vino cotto wine production was written by Battistelli, Noemi;Perpetuini, Giorgia;Piva, Andrea;Pepe, Alessia;Sidari, Rossana;Wache, Yves;Tofalo, Rosanna. And the article was included in Food Research International in 2021.COA of Formula: C7H14O3 The following contents are mentioned in the article:

The aim of the present study was to assess the cultivable microbiota of “mothers” of Vino cotto collected from production of different years 1890, 1895, 1920, 1975, 2008. A total of 73 yeasts and 81 bacteria were isolated. Starmerella lactis-condensi, Starmerella bacillaris, Hanseniaspora uvarum, Saccharomyces cerevisiae, Hanseniaspora guillermondi and Metschnikowia pulcherrima were identified. Bacteria isolates belonged to lactic acid bacteria (Lactiplantibacillus plantarum and Pediococcus pentosaceus) and acetic acid bacteria (Gluconobacter oxydans). Remarkable biodiversity was observed for Starm. bacillaris, as well as L. plantarum and G. oxydans. Organic acids and volatile compounds were also determined Malic and succinic acids were the main ones with values ranging from 8.49 g/L to 11.76 g/L and from 4.15 g/L to 7.73 g/L resp., while citric acid was present at low concentrations (<0.2 g/L) in all samples. Esters and higher alcs. were the main volatile compounds detected followed by alkanes. This study permits to better understand the microbial communities associated to this product and could be considered a starting point for the definition of tailored starter cultures to improve the quality of Vino cotto preserving its typical traits. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9COA of Formula: C7H14O3).

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. 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.COA of Formula: C7H14O3

Polymeric protective coatings for MEMS wet-etch processes was written by Ruben, Kimberly A.;Flaim, Tony D.;Li, Chenghong. And the article was included in Proceedings of SPIE-The International Society for Optical Engineering in 2004.Reference of 763-69-9 The following contents are mentioned in the article:

Microelectromech. systems (MEMS) device manufacturers today are faced with the challenge of protecting electronic circuitry and other sensitive device structures during deep Si wet-etch processes. Etch processes of this nature require prolonged exposure of the device to harsh corrosive mixtures of aqueous acids and bases at higher than ambient temperatures A need exists for a spin-applied polymeric coating to prevent the exposure of such circuitry against the corrosive etchants. The challenge exists in developing protective coatings that will not decompose or dissolve in the etchants during the etch process. Such coatings require superior adhesion to the substrate without destroying the sensitive features below. Brewer Science, Inc., has developed a multilayer coating system for basic etchants which is compatible with a variety of semiconductor materials and offers protection against concentrated KOH etchants at prolonged exposure times of >8 h. In addition, a 2nd multilayer coating system is being developed for use with strong HF and other various mixed acid etchants (MAEs) for exposures of 30 min or longer. These materials are specifically designed to protect circuitry subjected to concentrated MAEs during the wafer thinning processes used by MEMS device manufacturers. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Reference of 763-69-9).

Ethyl 3-ethoxypropanoate (cas: 763-69-9) 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. 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.Reference of 763-69-9

Water whitening of solvent-cast thermoplastic polyhydroxyether thin films was written by Maples, Austin L.;Ferguson, Richard C.;Williams, Eric B.;Peterson, Robert;Delatte, David E.;Rawlins, James W.. And the article was included in Proceedings of the Annual International Waterborne, High-Solids, and Powder Coatings Symposium in 2018.Product Details of 763-69-9 The following contents are mentioned in the article:

System and conditionally specific water whitening of model epoxy corrosion control coatings were studied using thermoplastic polyhydoxyether films via UV – visible spectroscopy, attenuated total reflectance – fourier transform IR (ATR-FTIR) spectroscopy, differential scanning calorimetry, SEM, and internal stress measurements to quantify the size/spatial and material performance differences between controlled film variables. The void content and the corresponding reduction in light transmission was evaluated of the chem.-same polymers with differing mol. weights, which varied by the residual solvent concentration and composition in the film. Internal stress measurements yielded distinctly different profiles between annealing and exposure cycles and were mol. weight dependent and represent differences in material characteristics possible in all coatings materials. ATR-FTIR was utilized to compare water breakthrough times in relation to both mol. weight and residual solvent content. Greater solvent content resulted in an increase in water whitening and observed void formation and growth within the film. Lower mol. weight polymers exhibited these changes earlier in time, greater size and quantity vs. conditions and to a greater extent than films comprised of higher mol. weight, chem.-same polymers. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Product Details of 763-69-9).

Ethyl 3-ethoxypropanoate (cas: 763-69-9) 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, including apples, durians, pears, bananas, pineapples, and strawberries. 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.

Aquatic Toxicity Assessment of Esters Towards the Daphnia magna Through PCA-ANFIS was written by Asadollahi-Baboli, M.. And the article was included in Bulletin of Environmental Contamination and Toxicology in 2013.COA of Formula: C7H14O3 The following contents are mentioned in the article:

The widespread production of esters combined with their ability to migrate in different compartments, makes their environmental toxicity important. In this background, the multivariate image anal.-quant. structure-toxicity relationship (MIA-QSTR) method coupled to principal component anal.-adaptive neuro-fuzzy inference systems (PCA-ANFIS) was applied to assess the toxicity of esters to Daphnia magna. In MIA-QSTR, pixels of chem. structures (2D images) stand for descriptors, and structural changes account for the variance in toxicities. The ANFIS procedure was capable of correlating the inputs (PCA scores) with the toxicities accurately. The PCA-ANFIS also was statistically validated for its predictive power using cross-validation, applicability domain and Y-scrambling evaluation procedures. The satisfactory results (R_p² = 0.926, Q_LOO² = 0.887, R_L25 %O² = 0.843, RMSE_LOO = 0.320 and RMSE_L25 %O = 0.379) suggests that the QSTR model could be proposed as an alternative method for aquatic toxicity assessment of esters allowing possible application in the European Union regulation REACH. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9COA of Formula: C7H14O3).

Prediction of flash points of pure organic compounds: Evaluation of the DIPPR database was written by Alibakhshi, A.;Mirshahvalad, H.;Alibakhshi, S.. And the article was included in Process Safety and Environmental Protection in 2017.Electric Literature of C7H14O3 The following contents are mentioned in the article:

The flash point is one of the most important flammability properties of compounds for the design of inherently safe processes. Many models have been developed to predict the flash point using the DIPPR database. However, for only 740 of the 1628 organic compounds available in the DIPPR database, the data for both flash point and normal b.p. were exptl. determined For the other compounds, at least one of these properties was predicted and therefore is not appropriate for model development. The present study introduces a model to predict the flash points of pure organic compounds using their mol. structures and normal b.ps. The new model exploits the equality of the relative errors observed for the normal b.p. and flash point values predicted using the Joback method. Consequently, the relative error of the predicted normal b.ps. can be used as a scaling factor to modify the predicted flash points. The ability of the model to evaluate the accuracy of a database was investigated. The ratio of the relative error of the predicted flash point to the relative error of the predicted normal b.p. obtained using the Joback method was proposed as a measure to evaluate the accuracy of flash point data. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Electric Literature of C7H14O3).

Excimer laser photofragmentation/fragment detection for analysis of the oxygenated hydrocarbon ethyl-3-ethoxypropionate: implications for atmospheric monitoring was written by Dalyander, P. S.;Hahn, D. W.. And the article was included in Applied Spectroscopy in 2008.Category: esters-buliding-blocks The following contents are mentioned in the article:

The use of ArF excimer laser photofragmentation/fragment detection (PF/FD) is considered for the characterization of gaseous Et-3-ethyoxypropionate (EEP), a representative solvent within the class of oxygenated volatile organic compounds (VOCs). PF/FD measurements of EEP resulted in identification of the resulting photofragments as C₂ and CH, allowing photofragmentation pathways to be proposed for the parent mol. for the 1st time. PF/PD measurements of EEP recorded in the presence of sodium-based aerosol particles resulted in a reduced signal from the EEP, indicating adsorption onto the particulates, thereby demonstrating proof-of-concept that PF/FD can be used to study heterogeneous chem. reactions relevant to atm. chem. Finally, both time-integrated and time-resolved measurements of the EEP photofragmentation signal in varying concentrations of oxygen revealed that oxygen effectively acts as a dynamic quencher of the EEP signal. In consideration of oxygen quenching, care must be taken in calibrating/analyzing data in selected applications of PF/FD for VOC characterization (such as combustion emission monitoring) to account for the potential variability of oxygen concentration This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Category: esters-buliding-blocks).

Target exposure values with regard to repeated dose toxicity in the framework of an easy-to-use workplace control scheme was written by Roller, M.. And the article was included in Schriftenreihe der Bundesanstalt fuer Arbeitsschutz und Arbeitsmedizin, Forschung in 2005.Recommanded Product: Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:

By computer search, about 170 substances were found in the data base IUCLID which satisfied the following conditions: no MAK-value existent, no category 1 or 2 classification of mutagenicity, carcinogenicity or toxicity to reproduction, at least one IUCLID entry of an inhalation study of more than one day duration. Ninety nine of these substances could be grouped into four classes of chronic toxicity after target exposure values were derived with methods similar to the German ARW-concept. The allocation of the substances to the classes of chronic toxicity – based on IUCLID data – was compared with the allocation of the substances to the hazard bands of the British system COSSH Essentials – based on R-phrases. For about 2 thirds of the substances the uncertainty of the target exposure value and the class allocation is limited due to less satisfying input data. Despite the uncertainties, the anal. showed that in the sense of health protection not only R-phrases but also further toxicol. information should be incorporated into simple concepts of control methods, e.g. in terms of target exposure values, if derivation or control of formal occupational exposure limit values is not feasible.
