FIELD: chemistry.SUBSTANCE: invention relates to purification of wide fraction of light hydrocarbons (WFLH) from mercaptan compounds. Invention deals with method, in which mercaptan compounds interact with water solution of alkali, which is preliminarily mixed with alkylbenzyldimethylammonium chloride, where alkyl C-Cis taken in quantity 0.001-0.15 wt % in terms of hydrocarbon phase. Invention also relates to absorbent for purification of wide fraction of light hydrocarbons from mercaptan compounds.EFFECT: increased degree of removal of mercaptan compounds from WFLH, first of all with higher molecular weight (Cand higher).2 cl, 2 tbl, 4 ex |
