FIELD: chemistry.
SUBSTANCE: invention relates to petrochemistry. The invention relates to cleaning oil, gas condensate and fractions thereof from mercaptans and hydrogen sulphide by treating starting material with an organic reagent in form of dioxazine R-[N(CH2)3O2]n, where n=1, 2, R is an alkyl, cycloalkyl, aryl, alkyl aryl, oxyalkyl group, which is pre-synthesised by reacting aqueous formaldehyde solution with primary amines R-NH2, and subsequent treatment of the starting material with the obtained reagent, the composition of which further includes tertiary amines N(R')3, where R', for primary and tertiary amines, has values similar to those for dioxazine, wherein tertiary amines in amount of 0.5-2.0 wt % are added to formaldehyde at temperature of 20-80°C.
EFFECT: high degree of purification of oil, gas condensate and fractions thereof from mercaptans and hydrogen sulphide, high content of dioxazine in the reagent, low specific consumption of the reagent for cleaning oil.
