Synthesis of Ethyl Crotonate by Microwave Catalysis Shao Shixiang, Zhang Tingting, Chen Huanxin, Fan Jinyan, Meng Qing (Department of Biotechnology and Chemical Engineering, Tianjin Institute of Technology, Tianjin 30019) Abstract Ethyl crotonate was synthesized by esterification of crotonic acid with alcohol in the presence of microwave system. The optimal conditions of the microwave catalysis were determined by means of orthogonal experimental design. Several experimental factors such as reaction time, alcohol-acid ratio, were discussed. The result showed that the reaction rate could be accelerated by microwave impulse.
