FIELD: chemistry.
SUBSTANCE: invention is used in propellant production for transport, which has low impurity level of sulphur and/or azote. Hydrocarbon material in oxidation zone is engaged with immiscible phase which contains acetic acid, water and oxidising agent that contains hydric dioxide and hydrogen acid. After separation, hydrocarbon phase containing oxygenated impurities are delivered to infusion zone in which part of remaining oxygenated impurities are extracted with the help of acetic acid aqueous solution. Infusion flow is delivered to separation zone for acetic acid reduction and, optionally, for the second delivering into oxidation and infusion zones.
EFFECT: simplification of the method and degree increase of cleaning.
