Title:
IMINE GUANIDINE DERIVATIVE CONTAINING FURAN SKELETON, AND PREPARATION AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/101160
Kind Code:
A1
Abstract:
Disclosed are an imine guanidine derivative containing a furan skeleton, the derivative comprising 2,5-furan diimine guanidine, an acceptable 2,5-furan diimine guanidine salt, and a solvate thereof. Also disclosed are a preparation method for 2,5-furan diimine guanidine, and the use thereof as an acidic gas absorbent and an anionic precipitant. The 2,5-furan diimine guanidine of the present invention can be conveniently regenerated and recycled after absorbing acidic gases, and the regenerating energy consumption thereof is low, the cost is reduced and the efficiency is improved, and the preparation method therefor is simple, the reaction conditions are mild, the reaction time is short, the yield is high, and the cost is low, and it is easy to realize large-scale preparation.
