有机锡催化碳酸乙烯酯与丁二酸二甲酯耦合反应
Coupling reaction of dimethyl succinate and ethylene carbonate using organotin catalyst
摘要
Abstract
A simple and ecient route for simultaneously synthesis of poly(ethylene succinate) (PES) and dimethyl carbonate (DMC) from ethylene carbonate (EC) and dimethyl succinate (DMSu) has been demonstrated in the presence of organotin catalyst. The effect of reaction parameters such as catalyst dosage,n(EC)/n(DMSu), reaction time,etc, on synthesis of PES and DMC was investigated. A reaction mechanism has been discussed with organotin catalyst. The results showed that Bu2SnO exhibited higher activity when the reaction time, catalyst dosage,n(EC)/n(DMSu), reaction temperature were 4 h, 0.75%( mol), 1 and 230℃, respectively in the standard atmosphere pre-polymerization step, and reaction pressure and reaction temperature were≤400 Pa and 210℃, respectively in the vacuum condensation step. The DMC yield was up to 70.08% and the intrinsic viscosity of PES was up to 0.622 dl·g−1.关键词
