Diethyl Ethylphenylpropanedioate - Preparation Method
Open Data Verified Data
Benzyl Cyanide is reacted with ethanol in the presence of sulfuric acid to form ethyl phenylacetate. After distillation, the obtained ethyl phenylacetate is subjected to condensation reaction with diethyl oxalate and sodium ethoxide, acid-separated by hydrochloric acid, and then subjected to ethylation by bromoethane to form diethyl phenylethylmalonate. Finally, the product is refined by fractional distillation under reduced pressure.

| production method | 1. Derived from diethyl phenylmalonate by ethylation. 2. Benzyl Cyanide reacts with ethanol in the presence of sulfuric acid to produce ethyl phenylacetate. After distillation, the obtained ethyl phenylacetate is subjected to condensation reaction with diethyl oxalate and sodium ethoxide, acid-separated by hydrochloric acid, and then subjected to ethylation by bromoethane to form diethyl phenylethylmalonate. Finally, the product is refined by fractional distillation under reduced pressure. Another production method is the condensation of ethyl phenylacetate with diethyl carbonate and bromoethane. |
