| Abstract: | A method for preparation of chlorimuron-ethyl from.Ethyl2-sulfamoylbenzoate and bis(trichloromethyl) carbonate as starting material.Ethyl2-sulfamoylbenzoate reacts with bis(trichloromethyl) carbonate to give ethyl2-methoxycar-bonylsulfamoylbenzoate.Chlorimuron-ethyl will be obtained after reaction of the above product with 2-amino-4-chloro-6-methoxypyrimidine.This is an economica method to prepare chlorimuron-ethyl in high yield and good purity,avoiding the shortcoming of the tradition route.The total yield reaches 76.7% based on ethyl2-sulfamoylbenzoate and the purity is 92.12%. |
| Keywords: | chlorimuron-ethyl bis(trichloromethyl) carbonate soybean herbicide compound |
