Ethyl Cyanoacetate Reactions

Abstract

Ethyl cyanoacetate is a chemical intermediate that has been frequently used. The esterification of cyanoacetic acid and absolute ethanol with a mixed catalyst yielded ethyl cyanoacetate (the same proportion of silicotungstic and p-toluene sulfonic acid as catalyst). The influence factors of the amount of catalyst, n (cyanoacetic acid): n (absolute ethanol), reaction time and reaction temperature on the esterification rate was investigated by orthogonal experiment of four factors and three levels. The product was analyzed by gas chromatography to determine the optimum reaction conditions
