Paragraph 0032, (2017/02/24)
The invention discloses a backing tests the past intermediate 3-amino-2-chloro acrolein preparation method. The method is to rice polishings chloric acid as the starting material, the methyl aniline with rice polishings chloric acid reaction, got the midbody 7 ; intermediate 7 intermediate hydrolysis of the organic acid in 8, intermediate 8 in ammonia water reaction to obtain the 3-amino-2-chloro acrolein. The invention adopts the methyl aniline as solid, low toxicity, nucleophilicity than aniline is strong, has high yield; the invention greatly simplifies the operating steps, the production cost is reduced, more favorable to commercial reaction; post-treating process of the present invention is more simple, the on the basis of the impurity removal efficiency is improved, further reducing the complexity of the operation of the process.
