N-乙基-N-苄基苯胺合成工艺研究

Synthetic Process of N-ethyl-N-benzylaniline

Ｎ－乙基苯胺、氯化苄和Ｉ２一次投入反应瓶，搅拌，升温至１００℃，反应４０分钟，滴加ＮａＯＨ溶液，间隔２０分钟测ｐＨ值，４小时滴碱完毕，保温２小时，静置分离，洗涤后得粗品，再经减压蒸馏即得成品。

N-ethyl anilin, benzyl chloride and I 2 are added into the flask, raised to 100℃, reacted for 40 min, followed by dropping of NaOH solution, pH measurement at an interval of 20 min, dropping of alkali within 4 hours. And then, the mixture is kept temperature for 2 hr, stilled for separation, cleaned to get the crude product, and finally distilled under reduced pressure to obtain the title product.
