FIELD: chemistry.
SUBSTANCE: method includes the initial paraffin wax hydrogenation, which is the wax produced by the Fischer-Tropsch synthesis, characterized by the content of soluble oils in MEK of more than 0.5 wt % and containing at least 0.1 wt % of oxygen containing hydrocarbons, to produce the hydrogenated wax and then the hydrogenated wax deoiling by subjecting the hydrogenated wax to deoiling processing through the fractional crystallization upto reduction in such a way the content of the hydrogenated wax soluble oils in MEK upto less than 0.5 wt % to obtain the purified wax with the average solidification point from 45°C upto 69°C, at determinating by means of the test procedure, set in ASTM D938.
EFFECT: method improves the wax deoiling efficiency.
