Polyolefin lubricating oil is one of the important synthetic lubricants.The copolymerization of cyclohexene and 1-12 olefins had been studied with aluminium chloride-isopropanol complex as the catalyst.The infLuence of various kinds of technological conditions, such as consumption quantity of the catalyst,molar ratios of the isopropanol to A1C13, reaction temperatures and reaction time on the yields of the products were studied.The optimum process conditions had been established as A1C13 mole fractions of 4%,isopropanol/A1C13 molar ratio of 0.5,reaction temperature of 50~60 °C and reaction time for 6h.Under these conditions, the influence of proportions of olefin materials on the properties of the products had been studied.The experimental results showed that, 1 : 2 was the best molar ratio of raw materials,the viscosity at 100 °C was 6.10 mm2/s,the viscosity index was 157,the condensation point was -35 °C ,and the yield of synthetic oil was 86%.The products had some advantages, such as lower viscosity, lower solidifying point and higher viscosity index, which proved the product was a kind of high quality polyolefin synthetic lubricant.%聚烯烃润滑油是重要的合成润滑油之一.采用AlCl3作催化剂对环己烯与1-十二烯烃的共聚反应进行了研究.考察了催化剂AlCl3的用量、n(异丙醇)∶n(AlCl3)、反应温度和反应时间对产品收率的影响.确定了最佳工艺条件,即x(AlCl3)=4％,n(异丙醇)∶n(AlCl3)=0.5,反应温度50～60℃,反应时间6h.在最佳工艺条件下,调节环己烯与1-十二碳烯的混合比例进行了实验,研究了产品的物化性能.实验结果表明:采用n(1-十二烯烃)∶72(环已烯)=2∶1时,可以合成100℃粘度为6.10 mm2/s,粘度指数为157,凝点为-35℃的聚烯烃合成油,收率为86％.具有粘度低、凝点低、粘度指数高的显著特点,是高质量的聚烯烃合成油.
