| Abstract: | Ten substituted phenyl isocyanates were obtained with bis(trichloromethyl)carbonate and substituted aniline.Factors such as mole ratio of raw materials,the solvent and the initiators were also studied.The results show that the yield of substituted phenyl isocyanates are 69.7%～92.4% when the reaction conditions are as follows:the mole ratio of bis(trichloromethyl)carbonate to substituted aniline is 1 ∶2,the initiator is triethylamine,the solvent is toluene,1,2-dichloroethane or ethyl acetate,the reaction time is 3.5～5.5 h. |
