在超声波作用下合成三苯甲醇，比较了含水量不同的乙醚，以及是否使用碘引发对反应的影响。结果表明，超声波对该反应具有很好的催化作用，并不一定要使用碘引发反应，虽然无水乙醚能够获得最高的产率，但是即使有水存在，三苯甲醇也能获得较高的收率，因此超声波催化对该反应有很好的促进作用。%This paper describes the synthesis of triphenylcarbinol under ultrasonic irradiation . The water content in reagent of ether and the use of iodine in the reaction are compared .The results show that the ultrasonic wave has a catalytic role on this reaction and the use of iodine initiation is not indispensable . Although water-free ether has a comparably higher yield ,triphenylcarbinol can be obtained at quite high rate even in the presence of water .Therefore ,the ultrasonic catalysis can effectively improve the reaction .
