FIELD: chemistry.
SUBSTANCE: inhibitor is obtained by mixing elementary sulphur with alkanolamine, selected from monoethanolamine, diethanolamine or methyldiethanolamine, in the presence of an activator. As the activator applied is hydrazine and/or symmetrical dimethylhydrazine and/or N,N-diethylhydroxylamine. The claimed absorbent for gas purification from acid components contains an inhibitor in a quantity of 0.01-0.5 wt % counted per sulphur.
EFFECT: increase of the thermal stability and reduction of the corrosion activity of alkanolamine absorbents.
