摘　　要：以AlCl3-乙酰丙酮络合物为催化剂,1-辛烯为原料齐聚合成了聚α-烯烃合成润滑油。考察了AlCl3物质的量分数、n(AlCl3)∶n(乙酰丙酮)、反应温度及反应时间对聚α-烯烃合成润滑油收率和性能的影响。结果表明,最佳工艺条件为AlCl3物质的量分数4%,n(AlCl3)∶n(乙酰丙酮)=2∶1,反应温度25℃,反应时间4 h,此条件下,可以合成黏度指数为173和凝点-40℃的聚α-烯烃合成润滑油。Poly-alpha-olefins synthetic lubricant（PAO） was synthesized with aluminium chloride-acetylacetone complex as the catalyst,and 1-octene as the raw material.The influence of mole fractions of AlCl3,molar ratio of AlCl3 to acetylacetone,reaction temperature and reaction time on the yield and properties of the PAO was investigated.The results showed that PAO with viscosity index of 173 and condensation point of-40 ℃ was synthesized under the optimum process condition as follows： AlCl3 mole fraction 4%,n（AlCl3）∶n（acetylacetone）=2∶1,reaction temperature 25 ℃ and reaction time 4 h.
