FIELD: chemistry.
SUBSTANCE: invention refers to a method for production of low-viscous, waxy synthetic poly-alfa-olefin base oils including co-oligomerization reaction of ethylene with octane-1 or decene-1 in presence of a catalyst at constant temperature and ethylene pressure, fractioning of the obtained liquid product and isolation of the target oil fraction while co-oligomerization reaction being carried out at a temperature of 150-180°C and ethylene pressure of 4.0-6.0 MPa in batch reactor with mixing at the rate of 500-550 r.p.m; sulphated aluminum oxide is used as a catalyst, and oil fraction with vapor boiling temperature of more than 250°C is isolated at atmospheric pressure.
EFFECT: increased output of the target oil fraction (up to 91,4 wt %), lowered kinematic viscosity at temperature of 100°C (to 2,0-3,5 mm2/s) and solidification temperature (below minus 65°C) of synthetic poly-alfa-olefin base oils which may be used as the base for hydraulic oils for space-rocker hardware operated at low temperatures.
