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（GC-MS）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 catalysts were 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 yield and selectivity of two-butylcarbonate-ended-BPA(DbC(1)) were higher than those obtained over Ph2SnO and (PhCH3)2SnO.
