COMPOSITION HAVING RING STRUCTURE AND TERMINAL AMINE GROUPS, AND USE THEREOF AS FLUE GAS ABSORBENT

摘要

Disclosed is a flue gas absorbent composition which contains a compound and water. The compound has a ring structure and includes terminal primary amine groups and substituted a- carbon atoms neighboring the amine groups. Further, a use of a solution of a compound having a ring structure and terminal amine groups as a flue gas absorbent is disclosed. The absorbent com¬ position includes a ring-structure compound having superior absorption ability when compared to conventional absorbents, thereby exhibiting excellent properties, i.e., flue gas absorption rate improved by 50 to 100% and flue gas absorption capacity improved by 200 to 400%, as compared with currently used absorbents such as monoethanolamine (MEA) and 2-amino-2-methyl-propanol (AMP).
