摘要:

研究了不同配位基团的有机锡化合物对甲基苯基碳酸酯(MPC)歧化合成碳酸二苯酯(DPC)反应的催化性能. 探究了电子效应和空间位阻对MPC歧化反应活性的影响, 结果表明, 有机锡化合物作为Lewis酸, 与锡原子配位基团的吸电子效应和空间位阻影响相应催化剂的酸性从而影响其反应活性, 电子效应的影响大于空间位阻的影响. 氧化氢氧丁基锡[BuSnO(OH)]催化剂具有最好的催化性能, 在BuSnO(OH)与MPC摩尔比为0.02, 180 ℃及反应2.5 h条件下, MPC的转化率达到89.7%, DPC选择性为99.3%.

Abstract:

The catalytic performances of organotin compounds for the disproportionation of methyl phenyl carbonate(MPC) to diphenyl carbonate(DPC) were investigated. The electronic effect and steric hindrance for the disproportionate reactivity of MPC to DPC catalyzed by organotin compounds were discussed. The results show that the organotin compound is used as Lewis acid to catalyze the disproportionation of MPC, the electronic effect and steric hindrance of the coordinating groups affect the acidity of active tin centers and therefore influence the reactivity. Moreover, the influence of electronic effect is greater than that of the steric hindrance. Butyltinhydroxide-oxide[BuSnO(OH)] catalyst exhibits the best catalytic performance. Under the optimum reaction conditions[n(Cat.)/n(MPC)=0.02, 180 ℃, 2.5 h], the conversion of MPC is up to 89.7% and the selectivity of DPC is 99.3%.
