从N-乙基邻甲苯胺合成过渡液中分离N,N-二乙基邻甲苯胺

Separating N,N Diethyl o methyl aniline from Synthetic Residue of N Ethyl o methyl aniline

从Ｎ－二乙基邻甲苯胺合成过渡液（含Ｎ，Ｎ－二乙基邻甲苯胺１２％）中用苯磺酰氯分离出Ｎ，Ｎ－二乙基邻甲苯胺，其提出率为８１．６７％。由此破坏了剩余过渡液中的共沸组成，为过渡液中其他组分的回收利用创造了条件。

This paper reports a method of using benzene sulfonechloride to separate N,N diethyl o methyl aniline from synthetic residue of N ethyl o methyl aniline.We have gotten 81.67% N,N diethyl o methyl aniline from the residue.
