| Abstract: | Dimethyl carbonate(DMC),which is called "Green Chemical",can substitute phosgene for the synthesis of 4-chlorophenyl isocyanate.The effect of reaction conditions on the synthesis of 4-chlorophenyl isocyanate was studied.The results showed that the optimal conditions were as follows: ZnO catalyst 0.06 g,n(DMC)∶n(4-chloroaniline)=8∶1,temperature at 80 ℃ and reaction time of 6 h.The yield of the product is 62.18%. |
| Keywords: | DMC 4-chloroaniline 4-chlorophenyl isocyanate green synthesis |
