【Abstract】 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.更多还原
