FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to a method for preparing poly-alpha-olefin compound. Method involves combined oligomerization of a mixture containing about from 60 to 90 weight% of 1-dodecene and about from 10 to 40 weight% of 1-decene in the presence of BF3 as a catalyst and alcoholic promoter at temperature in the range about from 20°C to 60°C followed by distilling the mixture and hydrogenation to yield poly-alpha-olefin. Product has kinematic viscosity in the range about from 4 to 6 centistokes at 100°C, loss by Noak mass in the range about from 4% to 9%, viscosity index in the range about from 130 to 145 and fluidity loss temperature in the range about from -60°C to -50°C.
EFFECT: improved method of synthesis.
