Beschreibung
Zusammenfassung:	FIELD: petroleum chemistry. ^ SUBSTANCE: invention relates, in particular, to methods for treatment of petroleum, gas condensate and their fractions from mercaptans and hydrogen sulfide. Method is carried out by treatment of the parent raw with organic reagent wherein dioxazines of the structural formula: are used wherein R means alkyl, aryl, oxyalkyl, alkylaryl groups; or their mixtures by preliminary adding tertiary amine N(R')3 to the reagent composite wherein R; means alkyl, aryl, oxyalkyl groups; in the amount 0.01-0.05 wt.-%. Reagent is taken in the amount 0.25-0.05 per 1 mole of mercaptan of hydrogen sulfide sulfur. Raw is treated at 10-40°C. ^ EFFECT: enhanced degree of raw treatment, decreased consumption of reagent. ^ 3 cl, 1 tbl
