Abstract (en)
[origin: WO2009156618A1] The degradation of an absorbent solution comprising organic compounds provided with an amino functional group, in aqueous solution, is substantially reduced in the presence of a small amount of degradation-inhibiting agents having a thiocarbonyl functional group which are defined by the general formula: Formula (I). The absorbent solution is used to deacidify a gaseous effluent.
