A STUDY ON THE SYNTHESIS OF METHYL ACRYLATE FROM ACRYLONITRILE Esterification of acrylamide sulfate and Separation of distillate by extraction

ACRYLONITRILE로부터 METHYL ZCRYLATE 합성에 관한 연구 Acrylamide sulfate의 에스테르 반응과 유출분의 추출분이.

There are many industrial methods for the synthesis of methyl acrylate. According to Goodrich's patent, acrylamide sulfate is obtained by synthesis. Then, on it's esterification the injecting condition of methanol is investigated and the several inhibitors are used. And methyl acrylate in condensed distillate is separated by extraction. Consequently, it is better that reaction time is 4 hr at 140°C, and the yield is increased with amount of methanol. Ferrous sulfate is superior to the Goodrich's hydroquinone as an inhibitor, and water is suitable as the other component of extraction.
