摘　　要：以离子液体Et3NHCl-AlCl3催化1-C14烯烃齐聚制备润滑油基础油(不同粘度级别的中粘度PAO),考察了反应温度和反应时间对齐聚反应的影响。结果表明,在25~75℃下反应1~4 h,由1-C14烯烃齐聚可制备高性能的润滑油基础油;齐聚物主要是由三聚、四聚、五聚体组成的混合物,粘度υ100℃=20.3~35.2 mm2/s,粘度指数153~183,倾点-26^-36℃,相对分子质量742~836。Oligomerization of 1-tetradecene is studied to make lubricant base oil with Et3NHCl-Al Cl3 catalyst. The medium viscosity grades PAO have been synthesized. The effects of the reaction temperature and reaction time on oligomerization were investigated. The results show that the reaction for 1 ~ 4 h at 25 ~75 ℃,1-tetradecene can also be used to make high performance lubricant base oil and the oligomer is a mixer mainly composed of trimer and tetramer and pentamer of 1-tetradecene,and possessed medium viscosity( υ100 ℃= 20. 3 ~ 35. 2 mm2/ s),high viscosity index( 153 ~ 183),low pour point(-26 ^-36 ℃),moderate relative molecular mass( 742 ~ 836),which is a desired component for lubricant base oil.
