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%.

关键词: 二氧化碳, 邻氯丙醇, 三乙胺, 碳酸钾, 碳酸丙烯酯

Abstract: Synthesis of propylene carbonate from CO2 and o-chloropropanol, which is the intermediate of producing propylene oxide, was studied. Triethylami ne and potassium carbonate exhibited high activity. The cataly tic system of K2CO3-N(Et)3 has higher yield of propylene carbonate than u se of them by single.

Key words: carbon dioxide, o-chloropropanol, triethylamine, potassium carbonate, propylene carbonate
