摘　　要：研究了一种以二氧化碳和邻氯丙醇为原料合成碳酸丙烯酯的新方法,并比较了几种无机碱和有机胺的催化活性.结果表明,碳酸钾与三乙胺的催化活性较高.与两者单独使用相比,K2CO3-N(Et)3体系的催化效果更好,在优化条件下,邻氯丙醇转化率高达98%,碳酸丙烯酯选择性为95%.A new route of synthesis of propylene carbonate （PC） from CO2 and o-chloropropanol was studied. Catalytic activity of several inorganic solid bases and an organic amine was compared. The results show that potassium carbonate and triethylamine both exhibit high activity. The catalytic system of K2CO3-N（Et）3 has higher PC yield than that of either K2CO3 or N（Et）3 itself. Under the optimal reaction conditions, 98 % o-chloropropanol conversion and 95 % PC selectivity were obtained on K2CO3-N（Et）3.
