摘要
以间二甲苯为原料,浓硫酸作磺化剂,在碱性或酸性条件下对产物进行分离,得到3,5-二甲基苯磺酸.通过IR和1H-NMR对化合物的组成和结构进行了表征,探讨优化了反应条件,该方法具有操作简便、反应快、产率较高的特点.
Using the antioxidant intermediate compound m-xylene as the raw material, and concentrated sulfuric acid as the sulfonating agent, under alkaline or acidic conditions, the product was separated, and then obtained 3, 5--dimethyl benzene sulfonic acid. The composition and structure of the compounds were characterized by IR and ^1H-NMR, investigated the optimization of the reaction conditions, This method has the features of easy operation, fast response, and high production.
