中文摘要：
报道了超声波作用下合成二苯甲醇的方法．即以二苯甲酮为原料，锌粉-氢氧化钠为还原剂、乙醇为溶剂，超声波条件下合成二苯甲醇,同时对影响收率诸因素进行考察，确定了最佳反应条件：n（二苯甲酮）：n（锌粉）=1：3（摩尔比），超声波功率为500W，辐射时间为20min时，收率可达90．2％．
英文摘要：
The synthesis of diphenylmethanol under ultrasonic wave irradiation was studied. Using Zn-sodium hydroxide as reducing agent and ethanol as solvent, diphenylmethanol was synthesized from diphenyl ketone. The suitable reaction conditions were as follows： 1.83 g （10.0 mmol） diphenyl ketone, 1.97 g（30.0 retool） Zn,1.97 g （49.3 retool）sodium hydroxide,20 mL 95% ethanol,reaction time is 20 min. The yield of diphenylmethanol was up to 90.2%. This method possessed a series advantages, such as high yield, and shorted experimental time.
