Abstract
The synthesis methods of isophorone diisocyanate were summarized,the synthetic method was compared in detail,and advantages and disadvantages of that with phosgene,urea or dimethyl carbonate as raw material for synthesis of isophorone diisocyanate were analyzed. The isophorone diisocyanate synthesis of dimethyl carbonate method and using a new catalyst was optimized mainly. The reaction condition was mild,the conversion rate was higher,energy consumption was lower,and product and the catalyst was easy to separate.
