Method for preparing aliphatic amine compound
-
Paragraph 0071-0073, (2020/05/14)
The invention discloses a method for preparing an aliphatic amine compound, comprising the following steps: using furfuryl amine or a furfuryl amine derivative as a raw material, and carrying out hydrogenolysis in the presence of a supported metal catalyst to obtain the aliphatic amine compound. According to the method disclosed by the invention, the aliphatic amine compound is prepared by catalyzing hydrogenolysis of the biomass-based furfuryl amine and the derivative thereof for the first time. The catalyst has high activity and high product selectivity. According to the method, a biomass-based compound is used as a raw material to prepare the aliphatic amine compound, and the requirements of sustainable development and green chemistry are met. The aliphatic amine compound prepared by the method has high selectivity, and is convenient for separation and purification of products. After the reaction of the method is finished, the catalyst is easy to separate and can be recycled, so that the method has a good application prospect.

Paragraph 0025; 0027; 0037; 0039, (2019/10/23)
The invention discloses a synthetic method 6-amino-1-hexanol. According to the synthetic method 6-amino-1-hexanol, chlorosulphonyl isocyanate and 1, 6-hexanediol are taken as main raw materials, one-pot method is adopted to synthesize 6-amino-1-hexanol. The synthesis route comprises following steps: 1, under the catalyst effect of a tertiary amine, chlorosulphonyl isocyanate and a primary alcoholare reacted to generate a Burgess reagent, 1, 6-hexanediol is added to generate an intermediate 6-hydroxyhexyl carbamic acid; and 2, the intermediate 6-hydroxyhexyl carbamic acid synthesized in step is subjected to projecting group removing directly without separation so as to obtain target product 6-amino-1-hexanol. The synthetic method is low in cost, simple in reaction conditions, few in reaction steps, short in time, and high in purity and yield of finished product 6-amino-1-hexanol.
