Article Preview

Abstract:

In this study, SbCl3 as catalyst to benzaldehyde, ethyl acetoacetate and urea as raw material in the ultrasonic radiation synthesis of 3,4-Dihydropyrimidin-2(1H)-ketone. According to the orthogonal design optimization experiment, optimization method ultrasonic extraction technology, and ultimate pass to get the best synthetic condition for: material ratio 1.0,1.0,1.5(mol), ultrasonic power 100 w, ultrasonic time 2 hours, ultrasonic temperature 65°C, the yield is 61.08%.
