Paragraph 0042-0047, (2021/11/26)
The invention belongs to the field of fine chemical engineering, and relates to a novel method for producing 2-amino-1, 3-propylene glycol by a JIT method, the novel method is composed of a catalytic chlorination reaction and a catalytic amination reaction, glycerol is chlorinated by hydrogen chloride under the catalysis of zinc chloride to obtain 2-chloro-1, 3-propylene glycol, and the 2-chloro-1, 3-propylene glycol is subjected to a catalytic reaction by urotropin to obtain 2-chloro-1, 3-propylene glycol.
