摘要
聚α-烯烃是高品质的润滑油基础油。使用AlCl3-季戊四醇络合催化剂,对1-辛烯齐聚反应进行研究,考察催化剂物质的量分数、季戊四醇与A1Cl3物质的量比、反应温度和反应时间对聚烯烃收率及不同聚合物选择性的影响。结果表明,1-辛烯齐聚合成聚α-烯烃最佳工艺条件:AlCl3物质的量分数为2%,季戊四醇与AlCl3物质的量比为0.5,反应温度为50℃,反应时间为4 h,聚烯烃收率约为93.4%,合成的聚α-烯烃产品中润滑油的理想组分三聚体和四聚体选择性较好。
Poly-alpha-olefins are high quality lubricants base oil. Using aluminum chloride-pentaerythri- tol complex as the catalyst, the oligomerization of 1-octylene was studied. The effects of molar fractions of the catalyst, molar ratio of the pentaerythritol/AlCl3 , reaction temperature and reaction time on the yield of poly-alpha-olefins and the selectivity to polymer were investigated. The results showed that poly-alpha-ole- fins yield of 93.4% was attained under the optimal process condition of synthetic lubricant as follows ： using 1-octylene as the raw material, AlCl3 molar fraction 2% , pentaerythritol/AlCl3 molar ratio 0.5, reac- tion temperature 50 ℃, reaction time 4 h. The product of poly-alpha-olefins was mainly consisted of tri- mers and tetramers, which were the ideal lube components and had better selectivity.
