摘　　要：通过格氏试剂法合成了3种有机锡催化剂二(三氟甲苯)氧化锡((PhCF3)2SnO)、二苯基氧化锡(Ph2SnO)和二甲苯基氧化锡(PhCH3)2SnO,研究了有机锡催化剂对BPA与DBC反应的影响.采用红外(IR)及X射线光电子能谱分析(XPS)对合成的催化剂进行了结构表征,并通过气相色谱(GC)及气相色谱质谱联用(GCMS)对合成的聚碳酸酯中间体进行分析.结果表明:以(PhCF3)2SnO为催化剂时,聚碳酸酯中间体(双酚A二丁基碳酸酯DbC(1))的产率及对其的选择性均较高,均高于以Ph2SnO和(PhCH3)2SnO为催化剂时得到的DbC(1)的产率及选择性.Organic tin oxide catalysts（PhCF3）2SnO, Ph2SnO and （PhCH3）2SnO were successfully synthesized by using Grig-nard reagent method, and the reactions between BPA and DBC over the synthesized organic tin oxide catalystswere also studied. The structure of the synthesized catalysts were characterized by X-ray photoelectron spec-troscopy （XPS）and Fourier transform infrared spectroscopy （FT-IR） , and the reaction products were ana-lyzed by GC and GC-MS. The results showed that when the （PhCF3）2SnO was used as catalyst, the yieldand selectivity of two-butylcarbonate-ended-BPA（DbC（1）） were higher than those obtained over Ph2SnO and（PhCH3）2SnO.
