<p>Absorbent solution (A) comprises: (a) at least one amine; (b) water; and (c) at least one degradation-inhibitor compound to reduce the degradation of the amine, where the degradation-inhibitor compound has phenyl structure (I). Absorbent solution (A) comprises: (a) at least one amine; (b) water; and (c) at least one degradation-inhibitor compound to reduce the degradation of the amine, where the degradation-inhibitor compound has phenyl structure of formula (I). R1-R6 : A, B1, C1, D, E, F1 or G; A : -NO 2group; B1 : H; C1 : -W1-X group; W1 : O or S; D : -C(=O)-O-V1; X, V1, Y1 : H, 1-12C hydrocarbyl, alkali or alkaline earth element, monovalent or multivalent metal, ammonium cation (NH 4 +>) or resulting from protonation of an amine function or phosphonium cation; E : -S(=O) 2-O-Y1; F1 : 1-12C hydrocarbyl group; G : phenyl group of formula (II); Z : covalent bond, O, S, N-R12 unit or linear or branched 1-20C hydrocarbyl group; and R12 : H or 1-12C hydrocarbyl group. Provided that: one to three radicals of R1-R6 corresponds to the definition of A; at least three radicals of R1-R6 are B1-G; up to three radicals of R1-R6 corresponds to the definition of C1; up to three radicals of R1-R6 corresponds to the definition of D; up to three radicals of R1-R6 are E; up to three radicals of R1-R6 corresponds to the definition of G; one to three radicals of R7-R11 corresponds to the definition of A; at least three radicals of R7-R11 are B1-F1; up to three radicals of R7-R11 corresponds to the definition of C1; up to three radicals of R7-R11 corresponds to the definition of D; and up to three radicals of R7-R11 corresponds to the definition of E.
