绿色化学在异氰酸酯合成中的应用

Application of green chemistry in synthesis of isocyanates

介绍了近十年来异氰酸酯在绿色合成中的研究进展。分析了绿色原料、反血工艺、催化剂及友好溶剂四方面的优点及不足,阐述了其反应机理,并对非光气法合成异氰酸酯的前景做了展望。同时,分别介绍了脱水剂选择和摧化剂选用的研究进展。最后,指出发展绿色合成异氰酸酯的可行性和重要性。

The recent development of isocyanates by using green synthesis is summarized. The merits and the shortages of the synthesis in green rawmaterial,reactiontechnology,catalyst and solvent are introduced,and the reaction mechanism are also discussed. Further studies about synthesizing isocyanates by using the non-phosgene method are also discussed. While the choose of the dehydration agent and catalyst introudured. At last the importance and the feasibility is indicated.
