【Abstract】 The optimal synthetic conditions of high efficient herbicide, 1,2,4-triazole-sulfonic acid, 1-[diethyl(amino)carbonyl]-2,4,6-trimethylphenylester were studied in this short paper, and the obtained optimal conditions included: triazole intermediate: trimethylhydroxybenzene: triethylamine = 1∶1.05∶1.5, the reaction temperature of 30℃ and the reaction time of 3 h. Besides, the fundamental application of 1,2,4-triazole-sulfonic acid, 1-[diethyl(amino)carbonyl]-2,4,6-trimethylphenylester as the high efficient herbicide was also investigated. This chemical is easy synthesized and the yield can reach about 95%, and it can widely and easily kill unwanted plant and to be easily processed.更多还原
