Abstract
The invention discloses a preparation method of an allyl amine mixture. The preparation method includes following steps: S1, pouring a catalyst into a reation kettle, adding a certain amount of ammonium hydroxide, rising temperature, and adding chloropropene for ammonolysis reaction; S2, holding the temperature of the step 1, and adding liquid caustic soda; S3, rectifying a reaction product to evaporate water and excessive ammonia; S4, at corresponding temperature, collecting fraction-monoallyl amine; S, at corresponding temperature, collecting fraction-diallyl amine; S6, at corresponding temperature, collecting fraction-trially amine; S7, adding caustic soda flakes into a collected fraction mixture, and performing liquid separation to obtain. The preparation method is mild in reaction condition, ammonium hydroxide is used to replace ammonia in existing methods, and complex ventilation equipment is not needed, so that production cost is saved; by adding the caustic soda flakes, water absorbing effect can be realized, purity of the allyl amine mixture prepared by the method can be effectively improved, and the preparation method is simple to operate, high in yield and worthy of popularization.
