摘要
介绍了超声化学的原理和实验室常用的超声设备 .评述了超声在均、多相有机反应中的应用 .超声在均、多相反应中除可以提高反应速率 ,有时也可以改变反应路线 .在相转移催化反应体系中 ,超声能够取代相转移催化剂 。
The principle of sonochemistry and ultrasonic apparatus for chemical laboratories are introduced. Applications and uses of ultrasound in homogeneous and heterogeneous organic reactions are also discussed. Ultrasound, in comparison with normal reaction, is able to enhance reaction rates and product yields. Sometimes it may change reaction pathway. Ultrasound may replace phase-transfer catalysts in phase-transfer catalysis reactions and facilitate the reaction.
