研究了超临界二氧化碳中α-氨基酸催化二氧化碳与环氧化物环加成反应合成环状碳酸酯,发现组氨酸的催化活性最高.在二氧化碳压力为8MPa、反应温度130℃、反应时间48h、组氨酸加入量为0.8mol%的条件下,二氧化物可以顺利的与各种环氧化物反应,以高的选择性和产率生成相应的环状碳酸酯. It was found that the catalytic activity of histidine was the highest when the α-amino acid was used to catalyze the cycloaddition reaction of carbon dioxide with epoxide to form cyclic carbonate. Under the conditions of carbon dioxide pressure of 8MPa, reaction temperature of 130 ℃ and reaction time of 48h, Under the condition of adding 0.8mol% of alanine, the dioxides can react with various epoxides smoothly and produce the corresponding cyclic carbonates with high selectivity and yield.
