실험 절차

A mixture of 20 g of 3-bromophenol, 92 g of ethyl acrylate and 1.8 ml of Triton B (35% in methanol) was boiled at reflux overnight. After distilling off the excess acrylate at normal pressure, the residue was distilled in a high vacuum. There were obtained 16.7 g of ethyl 3-(m-bromophenoxy)propionate as a colorless oil, boiling point 107°-110° C./67 Pa.
