对氨基-N,N-二甲基苯胺生产方法的改进

Improvement on Production Process of p-Amino-N,N-dimethylaniline

阐述了采用液碱(苛性钠溶液)代替氨水生产对氨基-N,N-二甲基苯胺的方法。与传统的氨水法相比,液碱法具有产品收率高、污染小、质量稳定及有利于后续处理单元操作的优点。

A improved process of p-amino-N,N-dimethylaniline applied caustic soda solution as materials was introduced. Compared with the process with ammonia liquor, this new process had many advantages of high yield, small pollution and stable quality.
