摘　　要：以多聚磷酸为脱水剂,二苯亚砜分别与二苯硫醚,二苯基醚和联苯反应制备了三种芳取代三苯基硫鎓盐。该反应条件温和,反应温度为40～50℃,时间为6～8h。其中4(苯硫基)三苯基硫六氟磷酸盐的收率为87.6%。对三种硫鎓盐的紫外光谱和红外光谱进行了详细的研究。三种硫盐对环氧树脂具有良好的固化性能。Three kinds of aryl-substited tri-benzyl sulfonium salts [(4-phX)phSph_2]PF_6[X=S,O] were prepared by the condensation of biphenyl sulfoxide with biphenyl sulfide, biphenyl ether of 1,1'-biphenyl using PPA as dehydrating agent. The reaction conditions were rather mild (temperature between 40～50 ℃,reactive time 6～8 h). The yield of 4-(phenylthio) triphenylsulfonium hexafluorophosphate was 87.6%. These three sulfonium salts are good curing agents for epoxy resin..
