Synthesis of acrylic monomers based on renewable raw materials. Part II. Synthesis of acrylic esters was written by Komon, Tomasz;Jamroz, Malgorzata E.;Niewiadomski, Piotr;Malanowski, Michal;Kijenski, Jacek. And the article was included in Polimery (Warsaw, Poland) in 2012.Recommanded Product: Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:
The esterification reaction of acrylic acid with ethanol and l-butanol in the presence of heterogeneous solid catalysts such as: sulfonated ion-exchange resins based on styrene-divinylbenzene (Amberlyst) or perfluoroethylene (Nafion) matrix, silicotungstic acid supported on silica, tungstic oxide or zirconium sulfate supported on zirconium oxide and mesoporous cellular foam with arylsulfonic groups, was investigated. The reactions were carried out in a solvent. The highest catalytic activities per unit weight of catalyst were observed for Amberlyst, Nafion NR50 and silicotungstic acid supported on silica, while the lowest activities were seen for Nafion SAC-13 and zirconium catalysts. The activity values (per proton) of solid acids were significantly different from those calculated by weight of catalyst and reached the highest value for Nafion SAC-13 composite. 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 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. 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
