FIELD: mining.
SUBSTANCE: invention refers to method of refining oil, gas condensate and oil fractions from mercaptans by means of catalyst alkali-free liquid phase oxidising de-mercaptanisation at temperature 20-50°C using as catalyst a homogenous liquid composition containing 15-20 wt % of copper chloride or bromide (II), 30-50 wt % of alcohol C1-C3 or mixture of the said alcohols, 15-45 wt % of solvating organic additive from row of alkylsulphoxides and alkylamides of linear or cyclic structure, water to 100% - the rest.
EFFECT: increased efficiency of refining.
