Abstract
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.
