摘要

A composite amine absorbent is an absorbent dissolved in water for absorbing CO 2 or H 2 S in gas, or both of them, which comprises:
1) at least one amine compound, and
2) a disulfide compound as an oxidative degradation inhibitor for the absorbent,
wherein the disulfide compound is a compound represented by the following Chemical Formula (I).
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒR 1 -S - S-R 2 ·· ·€ƒ€ƒ€ƒ€ƒ€ƒ(I)
in the formula, R 1 or R 2 is any one of an alkyl group with 1 to 4 carbon atoms, a hydroxyethyl group, a carboxyethyl group, a cyclohexyl group, and a dibutylthiocarbamoyl group.
