PHENYL ETHYL PROPIONATE FOR SYNTHESIS PRODUCT CODE CASR NO. 188745 SYNONYMS Phenethyl propionate C.I. NO. -- (122-70-3) ATOMIC ORMOLECULAR FORMULA OC 11 H 14 2 ATOMIC ORMOLECULAR WEIGHT 178.23 PROPERTIES -- C 11 H 14 O 2 PARAMETER LIMIT Description Colourless liquid. Solubility Miscible with alcohols and ether. Minimum assay (GC) 0 98.0%.The invention relates to the technical field of chemical synthesis, and particularly relates to a preparation method for synthesis of ethyl 3-ethoxypropionate; the ethyl 3-ethoxypropionate is synthesized by addition reaction of absolute ethanol and ethyl acrylate in the presence of a catalyst in a tubular reactor, the molar ratio of absolute ethanol to ethyl acrylate is 3: 1 to 100: 1, the.Ethyl propionate is a propanoate ester of ethanol. It has a role as a metabolite. Ethyl propionate appears as a clear colorless liquid with a pineapple-like odor.
Ethyl propionate was used to study the effect of its gavage administration on gastric toxicity in male F344 rats. Ethyl propionate, when used for contact dissolution of cholesterol gallstones, shows reduced side effects (attributable to increased blood levels) in piglets when compared to methyl tert-butyl ether.Ethyl propionate is a compound with formula C 2 H 5 (C 2 H 5 COO). It is the ethyl ester of propionic acid. It has a pineapple-like odor. Some fruits such as kiwis and strawberries contain ethyl propionate in small amounts. It is also used in the production of some antimalarial drugs including pyrimethamine.
The invention belongs to the technical field of chemical synthesis, and in particular relates to a method for preparing 3-ethoxy ethyl propionate. The method comprises a synthesizing step and a refining step, wherein the synthesizing step adopts ethanol and ethyl acrylate as raw materials to carry out addition under the action of a catalyst, and the catalyst adopts alkali metal or alkali.
