Study on the Synthesis of 2一Nitro-4,5一dimethyl Aniline

摘要/Abstract

摘要:

以3,4-二甲基苯胺为母体,以四氯化碳为溶剂,合成了2-硝基-4,5-二甲基苯胺,用正交实验确定了最佳原料配比n(母体):n(醋酐):n(硫酸)=1.00:1.20:1.13.产品收率81%左右,溶剂回收率95%以上.

Abstract:

2-Nitro一4,5-dimethyl aniline was syntheized by taking 3,4一dimethyl aniline as material and by taking carbon tetrachloride as solvent.The optimal rnole ratio of 3,4-dimethyl aniline to acetic anhydride to sulfuric acid was 1.00:1.20,1.13.The yield of product was about 81%,and the recovery of solvent is over 95%.
