摘　　要：采用乙酰苯胺氯磺化、N-乙基间甲苯胺磺酰胺化和水解三步合成N-乙基-N-对氨基苯磺酰基间甲苯胺。讨论了原料的用量、反应时间和温度对产率的影响。得到最佳的原料配比、反应温度和反应时间等最佳条件,并对反应过程中产生的废水、废气进行的合理化处理。N-Ethyl-N-p-aminobenzenesulfonyl-m-toluidine was synthesized from acetanilide by chlorosulfonation, sulfamidation and hydrolysis.The effects of the amount of raw materials, reaction time and temperature on the yield were discussed.The optimal ratio of raw materials, reaction temperature and reaction time were obtained, and the wastewater and waste gas generated in the reaction process were rationalized.
