摘　　要：在间歇高压釜中考察了超声波作用下HZSM-5催化环己烯水合反应的反应特征,研究了超声波对于环己烯水合反应的超声效应。结果表明,功率为900 W的超声波对于HZSM-5催化的环己烯水合反应具有最好的促进作用,一定反应条件下环己烯的转化率由6.1%提高到了8.6%,超声功率太低无法提供足够的空穴气泡,超声功率太高则会限制超声波的能量传递。The reaction behavior of cyclohexene hydration catalyzed by HZSM-5 was investigated with ultrasound in a batch stirring autoclave, and effect of the ultrasound on the hydration reaction was studied. The results showed that the ultrasound with an acoustic power of 900 W gave the best enhancement effect for cyclohexene hydration catalyzed by HZSM-5, and the cyclohexene conversion was increased from 6.1% to 8.6% under certain reaction conditions. It was proved that lower power ultrasound could not provide enough cavitation bubbles and higher power ultrasound should restrict the transmission of the ultrasonic energy in the reaction system.
