FIELD: chemistry.
SUBSTANCE: method of obtaining linear alfa-olefin oligomers in reactor, which contains liquid and gas phases, which are in equilibrium through surface of separation of gas/liquid phases, includes stages of catalytic oligomerisation of ethylene in presence of complex of nickel, palladium, cobalt, titanium, zirconium, hafnium, vanadium, chrome, molybdenum or tungsten into oligomer of alfa-olefin with average molecular weight from 50 to 350 with release of heat, and removal of heat in hear-exchanger, which is not in direct contact with liquid phase, using at least part of gas phase as cooling medium.
EFFECT: efficient prevention of heat-exchanger clogging-up.
