Oligomerization of 1-Butylene to Lubricant Catalyzed by Bis(tetramethyl cyclopentadienyl) Zirconium dichloride/MAO

摘要

Oligomerization of 1-butylene catalyzed by Bis(tetramethylcyclopentadienyl) Zirconium dichloride/MAO was investigated in detail under different conditions including reaction temperature, Al/Zr molar ratios, co-catalysts, concentration of catalyst to determine the optimal reaction conditions. The work shown that oligomer of 1-butylene in this catalyst system featured a kind of base oil of lubricant with pour point of -22°C, kinematic viscosity of 2999 mm~2/s at 40°C and 2530 mm~2/s at 100°C, viscosity index of 258 and a moderate average molecular weight. In addition, the oligomer obtained was characterized by 1H-NMR and IR.
