Abstract
The degradation of an absorbent solution comprising organic compounds provided with an amine function in aqueous solution is reduced considerably in the presence of a small amount of degradation-inhibiting additives belonging to the class of derivatives of pyrimidine or of triazine, at least one substituent of which contains a sulfur atom. The absorbent solution is employed for deacidifying a gaseous effluent.
