METHOD OF PRODUCING HIGH-VISCOSITY POLY-ALPHA-OLEFINS Russian patent published in 2016 - IPC C10M107/10 C08F210/14 C07C2/22

Abstract RU 2578595 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing high-viscosity poly-through oligomerisation of alpha-olefin in the presence of aluminium chloride catalyst used in the form of complex with toluene or ethylbenzene and vinyl acetate. Method is characterised by that the alpha-olefin used is a fraction C₈, C₁₀, C₁₂, C₁₄ or mixture thereof, the number of aluminium chloride is 1.5-2.2 wt% of the amount of alpha-olefin and not less than 27.5 wt% in complex with toluene or ethylbenzene and vinyl acetate, oligomerisation is carried out at temperature not higher than 100°C in isothermal conditions.

EFFECT: conducting the process for oligomerisation of alpha-olefin in the declared conditions enables to obtain Poly-Alpha-olefins with viscosity at 100°C of not less than 19 mm²/s, which can be used as components of grease for aircraft and as basic components of motor oils.
