Document Type and Number:
WIPO Patent Application WO/2018/176205
Kind Code:
A1
Abstract:
The present invention relates to aliphatic amine, a preparation method therefor, and applications thereof and especially applications in curing agents. The method for preparing aliphatic amine comprises: allowing reaction components containing amino acid and an amine compound capable of dissolving the amino acid, to have reactions, so as to obtain the aliphatic amine, the ratio of the content of the amino acid and the amine compound being 1:10000-1:1, preferably 1:100-1:2 and most preferably 1:10-1:2. The method for preparing aliphatic amine provided in the present invention has a high reaction rate, a high amino acid conversion rate, a high purity of an aliphatic product, a long catalyst life and easy purification of a reaction product.
