| Abstract: | A new process has been developed to synthesize N-ethyl-m-toluidine from m-toluidine and bromoethane by catalysis of triphase transfer catalyst (TBAT-PS) and a study of the effect of reaction conditions on the yield of N-ethyl-m-toluidine was also conducted.The yield of N-ethyl-m-toluidine was 93.6% under the optimum reaction conditions, i.e.the consumption of catalyst was 4.4 %, the molar ratio of m-toluidine to bromoethane was 1:1.6, and the reaction time was 6 h. |
