And the article was included in Industrial & Engineering Chemistry Research in 2010.Recommanded Product: Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:

A new group contribution-based models is presented to predict the upper flash point temperature of pure compounds based on a large dataset (1294). This neural network model uses several occurrences of 122 chem. groups in a pure compound to predict its related upper flash point limit. The model squared correlation coefficient, average percent error, mean average error, and root-mean-square error over the main dataset (1294 pure compounds) were 0.99, 1.7%, 6, and 8.5, resp. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Recommanded Product: Ethyl 3-ethoxypropanoate).

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. 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.Recommanded Product: Ethyl 3-ethoxypropanoate

A benzannulation strategy for the synthesis of phenols and heteroaromatic compounds based on the reaction of (trialkylsilyl)vinylketenes with lithium ynolates was written by Austin, Wesley F.;Zhang, Yongjun;Danheiser, Rick L.. And the article was included in Tetrahedron in 2007.Recommanded Product: Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:

(Trialkylsilyl)vinylketenes react with lithium ynolates to generate 3-(oxido)dienylketenes, which undergo rapid 6π-electrocyclization. The ultimate products of this benzannulation are highly substituted resorcinol monosilyl ethers, which are formed via a [1,3] carbon to oxygen silyl group shift. Further transformations of the benzannulation products are described providing efficient access to ortho-benzoquinones and benzofuran, benzoxepine, and benzoxocine ring systems. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Recommanded Product: 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. 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.Recommanded Product: Ethyl 3-ethoxypropanoate

Docking studies of tubulin-targeting C2-substituted 7-deazahypoxanthine analogs of marine alkaloid rigidins led to the design and synthesis of compounds containing linear C2-substituents. The C2-alkynyl analog I was found to have double- to single-digit nanomolar antiproliferative IC₅₀ values and showed statistically significant tumor size reduction in a colon cancer mouse model at nontoxic concentrations These results provide impetus and further guidance for the development of these rigidin analogs as anticancer agents. 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 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.Product Details of 763-69-9

Triphenylphosphine-catalyzed Michael addition of alcohols to acrylic compounds was written by Liu, Hai-Ling;Jiang, Huan-Feng;Wang, Yu-Gang. And the article was included in Chinese Journal of Chemistry in 2007.Reference of 763-69-9 The following contents are mentioned in the article:

A facile PPh₃-catalyzed Michael addition of alcs. to acrylic compounds was described. The reaction was carried out in open air at reflux temperature in the presence of 10 mol% PPh₃. Michael addition of saturated and unsaturated alcs. to acrylonitrile or acrylates was examined The reaction gave β-alkoxy derivatives with isolated yields of 5-79%. PPh₃ is cheaper and more stable than those trialkylphosphines previously used for the similar reactions, and the products can be easily separated from the reaction mixture via distillation 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

Lactones and terpenes were first detected in Chinese liquors. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Category: esters-buliding-blocks).

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. 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

A quant. structure-property relationship is presented to estimate the upper flash point of pure compounds using a multi-linear equation model with 8 parameters. All parameters are solely computed based on chem. structure. To develop this model, >3000 parameters were evaluated using the genetic algorithm multi-variate linear regression method to select the most statistically effective ones. Maximum average absolute relative deviation (mARD), ARD, squared correlation coefficient, and root mean squares of error from database (DIPPR 801) values for 1294 pure compounds were 25.76%, 3.56%, 0.95, and 17.42 K, resp.

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. 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.
