Abstract: Toluene alkylation can be enhanced through ultrasonic cavitation to increase the yield of ethyl benzene under lower temperature.Based on single factor experiment,the impacts of the volumetric fraction of toluene and the mass fraction of ethanol on product distribution are investigated.Combined with analysis on cavitation products,the reaction process is deduced.Response surface method is utilized to obtain the optimal process conditions for the synthesis of ethyl benzene from toluene alkylation as follows:the mass fraction of toluene is 20%,ultrasonic power is 850 W,and the ultrasonic time is 90 min.The optimal yield of ethyl benzene reaches 29.54% under the optimal conditions.
