The aim of this study was to evaluate the chem. composition and the larvicidal activity of Brunfelsia uniflora leaf and flower extracts against Aedes aegypti larvae. Twenty-four compounds were found in the leaf extract, and the major compounds were phytol (23.1%), 9,12,15-octadecatrienoic acid, Et ester (21.3%), and hexadecanoic acid, Et ester (12.8%). In the flower extract, twenty-four compounds were also identified and the major compounds were α-amyrin (35.7%), β-amyrin (16.4%), and (EE)-geranyl linalool (9.6%) by gas chromatog. coupled to mass spectrometry. The larvicidal activity was evaluated by larval immersion test. The lethal concentrations (LC) obtained from leaf extract were LC₅₀ = 4.89 and LC_99.9 = 11.14 mg/mL and from flower extract were LC₅₀ = 3.82 and LC_99.9 = 11.03 mg/mL, and the pos. control presented LC₅₀ = 0.40 and LC_99.9 = 1.14 mg/mL. Thus, B. uniflora extracts are promising alternatives to control A. aegypti larvae. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Related Products of 763-69-9).

Graft copolymer of sodium carboxymethyl cellulose and polyether polyol (CMC-g-TMN-450) improves the crosslinking degree of polyurethane for coated fertilizers with enhanced controlled release characteristics was written by Wang, Yang;Sun, Mingxue;Qiao, Dan;Li, Juan;Wang, Yajing;Liu, Weiyi;Bunt, Craig;Liu, Hongxia;Liu, Jinlong;Yang, Xiangdong. And the article was included in Carbohydrate Polymers in 2021.Quality Control of Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:

Novel superhydrophobic sodium CM-cellulose (CMC) modified polyurethane (MPU) was developed as the membrane material for controlled-release fertilizer (CRF) by crosslinking polymerization of 4,4′-diphenylmethane diisocyanate (MDI) and CMC-based modified polyol (CMP) which was made by grafting CMC onto polyether polyol (TMN-450). The modified polyurethane coated fertilizer (MPUCF) was prepared by using MPU as the membrane material through a fluidized bed device. Anal. results of 13C NMR showed that the coatings of PUCF and MPUCF were prepared by connecting hydroxyl to isocyanate groups to form a carbamate. MPU had lower water absorption rates than PU, and MPUCF coating showed excellent hydrophobicity. Scanning electron microscope (SEM) revealed that MPUCF coating surface was much more smooth and flat than that of PUCF. Furthermore, the nitrogen (N) release longevity of MPUCF can increased to 140 days when the coating rate was 5%. It is concluded that MPU was an excellent superhydrophobic coating material for CRF. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Quality Control 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. Polyesters are important plastics, with monomers linked by ester moieties. 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.

Hydrotreatment Upgrading of Bio-oil from Torrefaction of Pubescens in Alcohol over Pd/NbOPO₄ was written by Li, Jindong;Lv, Xiaoyan;Wang, Yue;Li, Qiuxing;Hu, Changwei. And the article was included in ACS Omega in 2018.Safety of Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:

Pd/NbOPO₄ multifunctional catalyst was prepared and used for catalytic hydrotreatment upgrading of bio-oil, which was obtained from low-temperature torrefaction (LTT) of pubescens and contained mainly lignin oligomers. The upgrading temperatures were investigated at 220-280 °C. Pd/NbOPO₄ exhibited good performance for the effective depolymerization of oligomers with increasing temperature It was revealed that both Bronsted acid sites and Lewis acid sites existed on NbO_x, which contributed to the cleavage of the C-O-C bond. Furthermore, esterification, hydrogenation, and O-alkylation of monomeric derivatives also occurred simultaneously during the depolymerization process. After hydrotreatment upgrading, the average mol. weight of bio-oil decreased from Mw = 320 Da (M_n = 298 Da) to Mw = 273 Da (M_n = 254 Da) and the bio-oil quality was improved dramatically. The oxygen content decreased from 29.53 to 9.78 wt %. The upgraded bio-oil obtained at 280 °C had a heating value of 40.48 MJ kg^-1, which was much higher than that of the original bio-oil (26.96 MJ kg^-1). This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Safety of Ethyl 3-ethoxypropanoate).

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. 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.

The study evaluates the contribution of the fructose and glucose’s degradation for the Madeira wine’s features. The browning index, antioxidant activity and volatile organic compounds developed by the glucose and fructose model systems simulating thermally processed sweet Madeira wines were assessed. Sixteen different fructose/glucose model systems were prepared in synthetic wine and stored at 50 °C for 4 mo. Then, three model wines were also submitted to 70 °C for 1 mo. The browning index and the antioxidant activity ranged between 0.00 and 0.27 AU and 3.0-65.3 mg(GAE)/L, resp. The development of several volatile organic compounds was demonstrated (up to 47). The identified compounds were mostly furans, with 5-hydroxymethylfurfural as the most abundant. For the first time, it was shown that the origin of sotolon in sweet wine can be associated with the acid-catalyzed fructose degradation mechanism. Other 2(5H)-furanones were also identified. It could be concluded that part of the browning, antioxidant activity and aroma compounds developed in sweet fortified wines is associated with the thermal degradation of fructose in acid medium. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Recommanded Product: Ethyl 3-ethoxypropanoate).

Recently we have developed new class of non-ionic oxime sulfonate PAG. The compounds generate various kinds of sulfonic acids, such as n-propane, n-octane, camphor and p-toluene sulfonic acid under Deep-UV exposure and are applicable for chem. amplified (CA) photoresists. The application-relevant properties of the compounds such as solubility in propylene glycol monomethyl ether acetate (PGMEA), Et lactate, Et 3-ethoxypropionate, and 2-heptanone, UV absorption, thermal stability with or without poly(4-hydroxystyrene) (PHS), storage stability in a neat form or in PGMEA solution with or without additives, sensitivity in a model resist formulation, dissolution inhibition efficiency during the development process and volatility were evaluated. The compounds exhibit good solubility in PGMEA, high sensitivity in pos. tone CA resist formulations, with Deep-UV exposure, and no significant volatility. Especially it was found that the compounds are superior in terms of thermal stability and storage stability, i.e., high thermal stability up to 188 degree(s)C in a phenolic matrix, and no change during storage in PGMEA at 60 degree(s)C for 5 mo.

Influence of Microwave Heating on Chemical Properties of Liquefied Lignocellulosic Residues was written by Briones, Rodrigo;Serrano, Luis;Sequeiros, Ane;Labidi, Jalel. And the article was included in Industrial & Engineering Chemistry Research in 2013.Quality Control of Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:

The chem. composition of liquid products obtained from liquefaction of several agro-industrial wastes was analyzed and the effects of microwave treatments were investigated, evaluating changes in chem. composition, structure, and phys. properties, looking forward to exploring new utilization routes or processing paths for these liquid products. Gas chromatog.-mass spectrometry (GC-MS) showed that the chem. components of liquefied products can be divided into several groups: furans, alcs., and esters and acid derivatives The microwave evaluation showed that irradiation at constant power levels affects the compositions of liquefied products. Fourier transform IR (FT-IR) spectroscopic anal. showed increases in the absorption bands of carbonyl and CH groups, which suggests that microwaves induced more intensive oxidation of hydroxyl groups into carbonyl groups. Elemental anal. indicated higher carbon and lower oxygen contents and higher heat heating value (20 MJ/kg) in treated products with respect to untreated samples. The use of liquefied products as a new energy source has advantages such as their liquid state, convenient energy value, and renewability.

193-nm multilayer imaging systems was written by Meador, James D.;Holmes, Doug;DiMenna, William;Nagatkina, Mariya I.;Rich, Michael D.;Flaim, Tony D.;Bennett, Randy;Kobayashi, Ichiro. And the article was included in Proceedings of SPIE-The International Society for Optical Engineering in 2003.Name: Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:

This paper highlights the performance of new materials that have been developed for use in 193-nm trilayer microlithog. The products are embedded etch masking layers (EMLs) and bottom antireflective coatings (BARCs). Both coatings are spin applied from organic solvent(s) and then thermoset during a hot plate bake. The EMLs (middle layers) are imaging compatible with JSR, Sumitomo, and TOK 193-nm photoresists. Best-case trilayer film stacks have given 100-nm dense and semi-dense L/S. Plasma etching, selectivities and solution compatibility performance of the EMLs meet or exceed proposed product targets. In addition, the EMLs exhibit both solution and plasma etching properties that should lead to successful rework processes for photoresists. The multilayer BARCs offer good thick film coating quality and contribute to excellent images when used in trilayer applications. Combining the EMLs, which are nearly optically transparent (k = 0.04) at 193-nm, with the new trilayer BARCs results in outstanding Prolith simulated reflectance control. In one modeling example, reflectance is a flat line at 0.5% on five different substrates for BARC thicknesses between 300 and 700-nm. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Name: Ethyl 3-ethoxypropanoate).

And the article was included in Eurasian Chemico-Technological Journal in 2009.Related Products of 763-69-9 The following contents are mentioned in the article:

The trend in the development and manufacturing of Complementary Metal Oxide Semiconductor (CMOS) image sensors is to miniaturize pixels on the chips and hence to improve their imaging characteristics by providing a higher image resolution As CMOS technol. scales down into submicron regions, the conventional color filters are no longer suitable for generating the desired optical d. The major drawback of the conventional color filters produced from pigment-based pos. tone photosensitive compositions, is the heterogeneous dispersion of pigments in photoresist composition resulting in color irregularities due to coarse particles of the pigments. One of the most perspective ways to solve this problem is a replacing the pigment with a dye as a coloring agent and thus, increasing solubility of the latter to obtain a homogeneous colored photoresist composition In this paper, several novel red dye-containing materials are synthesized and tested to provide a red-colored photosensitive composition This red-colored photosensitive composition is very promising for application as color filters for CMOS image sensors with high resolution and high level of integration architecture.

Ranking of aquatic toxicity of esters modelled by QSAR was written by Papa, Ester;Battaini, Francesca;Gramatica, Paola. And the article was included in Chemosphere in 2005.Computed Properties of C7H14O3 The following contents are mentioned in the article:

Alternative methods like predictions based on quant. structure-activity relationships (QSARs) are now accepted to fill data gaps and define priority lists for more expensive and time consuming assessments. A heterogeneous data set of 74 esters was studied for their aquatic toxicity, and available exptl. toxicity data on algae, Daphnia and fish were used to develop statistically validated QSAR models, obtained using multiple linear regression (MLR) by the OLS (ordinary least squares) method and GA-VSS (variable subset selection by genetic algorithms) to predict missing values. An ester aquatic toxicity index (ESATIN) was then obtained by combining, by PCA, exptl. and predicted toxicity data, from which model outliers and esters highly influential due to their structure had been eliminated. Finally this integrated aquatic toxicity index, defined by the PC1 score, was modeled using only a few theor. mol. descriptors. This last QSAR model, statistically validated for its predictive power, could be proposed as a preliminary evaluative method for screening/prioritizing esters according to their integrated aquatic toxicity, just starting from their mol. structure. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Computed Properties of C7H14O3).

Ethyl 3-ethoxypropanoate (cas: 763-69-9) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. 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.Computed Properties of C7H14O3

Molecular modeling of the standard state heat of formation was written by Bagheri, Mehdi;Yerramsetty, Krishna;Gasem, Khaled A. M.;Neely, Brian J.. And the article was included in Energy Conversion and Management in 2013.Formula: C7H14O3 The following contents are mentioned in the article:

The standard heat of formation is a basic thermophys. property required in determining enthalpies of reaction and in thermodn. stability analyses. Further, the enthalpies of formation are important in investigating bond energies, resonance energies and the nature of chem. bonds. Therefore, the development of accurate structure-based estimation methods for large varieties of chem. species is greatly beneficial in enhancing capability in process and product development. In this work, quant. structure-property relationship (QSPR) models were developed for a structurally diverse DIPPR dataset of standard heats of formation comprising 1765 pure compounds involving 82 chem. classes. We have employed both linear and nonlinear QSPR modeling techniques. The linear approach involves the use of constricted binary particle swarm optimization (BPSO) for feature selection and multiple-linear regression. In the nonlinear approach, the optimum network architecture and its associated inputs are identified using a wrapper-based feature selection algorithm combining differential evolution and artificial neural networks. Model predictions for the root-mean-square error of the BPSO and nonlinear approaches were 138 and 97 kJ/mol, resp. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Formula: C7H14O3).

Ethyl 3-ethoxypropanoate (cas: 763-69-9) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. 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.Formula: C7H14O3
