Oligomerization of C12-C14 internal olefins by using pentaerythritol-modified aluminum chloride catalyst was studied. Effects of aluminum trichloride amount,modifier amount, reaction time,reaction temperature on the yield of poly-internal-olefins (PIO) synthetic lubricant were investigated. The best reaction conditions was determined as follows:mass fraction of the aluminum chloride catalyst 2%, the amount of modifier pentaerythritol 0.25%, reaction temperature 85 ℃,reaction time 4h. Under above conditions,poly-olefins lubricant was synthesized from mixture of C12-C14 internal olefins. The viscosity of synthesized product was 7.15 mm2·s-1 at 100 ℃. The yield of poly-olefins lubricant with viscosity index 133 and solidifying point-39℃was 78%.
