摘　　要：以苯乙酮为原料,氯化亚砜(Cl2OS)为催化剂,在超声的条件下,合成三苯基苯,并探讨了超声功率,超声时间等因素对三苯基苯合成的影响,确定了合成反应的最佳条件为:超声功率60Hz,超声时间40min。在此条件下,收率可达83%～86%,与常规回流法相比,达到同等的产率,反应时间缩短了20min。目标物分子的结构经1H NMR和IR分析确证。1,3,5-triphenylbenzene was synthesized using acetophenone as raw material and thionyl chloride as catalyst.The effects of the ultrasound power and ultrasound time on the yields were discussed.Under the optimum reaction conditions, i.e., the ultrasound power is 60Hz, and ultrasound time of 40rain,the yield of 1,3,5-triphenylbenzene was 83%-84%.Compared with the conventional reflus method,it has reached the same yield and the reaction time has reduced 20 minutes.The structure of molecular was characterized by IH NMR and IR.
