摘要：对碳酸二甲酯和双酚A酯交换反应合成聚碳酸酯预聚体的反应精馏工艺进行了研究,分别考察了催化剂种类、加料方式、催化剂用量、原料配比和反应时间对反应的影响。结果表明:常压下,以(Bu2SnCl)2O为催化剂,反应温度140～180℃,催化剂用量n(Cat)∶n(BPA)=0.02,原料配比n(DMC)∶n(BPA)=4.5,反应12h,BPA的转化率可达82.36%。
The prepolymer of bisphenol A polycarbonate was synthesized by reactive distillation of dimethyl carbonate and bisphenol A. The catalyst concentration, the ratio of DMC to BPA and reaction time was studied. It found that the catalyst concentration was 0.02, the mole ratio of DMC to BPA was 4.5, the reaction time was 12 h, the conversion of BPA was 82.36%.
