Title:
ANILINE ANHYDRIDE, PREPARATION METHOD THEREFOR, AND POLYAMINOACID GRAFT CHAIN
Document Type and Number:
WIPO Patent Application WO/2022/062288
Kind Code:
A1
Abstract:
Disclosed are an aniline anhydride, a preparation method therefor, and a polyaminoacid graft chain. In the presence of an acid binding agent, an addition-elimination reaction is carried out between N-phenyl amino acid and Boc anhydride to obtain N-phenyl-Boc-glycine; and under a nitrogen atmosphere, the N-phenyl-Boc-glycine is subject to cyclization to obtain the aniline anhydride. The polyaminoacid graft chain can be obtained using the aniline anhydride disclosed by means of chemical grafting and thus be covalently bonded with fiber. The fastness is high, the wearability of fabric is not affected, and the problem of low fastness of water-repellent fabric obtained by coating is solved. The polyaminoacid graft chain is biocompatible, naturally degradable and environmentally friendly, and is consistent with the current trend of developing green chemicals.
