Abstract
Phosgenation reaction is the main technology to produce isocyanate in industrialization scale at present,which has advantages of mature process and high yields. However,there are still existing some potential hazards in safety and environmental protection because of phosgene and HCl as reactant and product in phosgenation reaction. This paper analyzed firstly the intrinsic defects of phosgenation reaction technology,combined with the phosgenation mechanism,and summarized the present states of improvements to the defects and concluded that two shortcomings of the technology can be solved step by step. Next,this paper retrospected the development history of phosgenation technology and summarized the internal mechanism of phosgenation progress based on reaction engineering,as well as presented the development tendency of phosgenation process. Finally,this paper briefly introduced some non-phosgenation technologies and agreed with that some of them will replace the present technology in the future but not in a short term while we compared the each features. Therefore,the further researches on phosgenation technology are necessary in promoting the technology of isocyanate industry and for the energy-saving and cost-reducing.关键词
