对氨基-N,N-二甲基苯胺制备

1. 以二甲苯胺为原料，经亚硝化，还原而得，反应式如下：

工艺过程：（1）亚硝化将稀盐酸及二甲基苯胺搅匀冷却至5℃以下，加亚硝酸钠溶液进行亚硝化，加毕，放置，过滤结晶，用1：1盐酸洗，再用盐酸与酒精的混合液再洗涤一次，抽干，得亚硝化物。（2）还原将上述粗品有水搅拌成糊状，再加工业浓盐酸，外面用冰水冷却，慢慢加入锌粉，加入温度不宜超过45℃。（3）提取加氢氧化钠溶液至碱性后，再用苯提取，苯溶液用无水碳酸钾干燥，用水浴回收苯，再减压蒸馏收集成品。其它制法由甲基橙还原或由对硝基二甲基苯胺用硫化钠或硫化钾还原而制得。工业上用香兰素萃取后废液为原料，经中和、萃取、蒸馏而得。该品对皮肤有刺激性，毒性比对苯二胺大8倍。

2. 其制备方法是用N，N-二甲苯胺与亚硝酸钠和盐酸进行亚硝化，再在铁粉和盐酸存在下进行还原，得到的N，N-二甲基对苯二胺盐酸盐用碱中和得产品。
也可以从香豆素生产中的废水用氨水中和至pH=7～8，加热至约40℃，沉淀8～12h，清除沉淀渣，用苯萃取中和液，然后减压脱苯即得N，N-二甲基对苯二胺。
