Fractionation of Poly1-Decene Based Oil Synthesized with AlCl3/Ethanol Cationic Catalyst in the Presence of Toluene Solvent

Polyα-olefin oil (PAO) was synthesized via cationic oligomerization of 1-decene as monomer, aluminum chloride as catalyst, ethanol as coactivator and toluene as solvent. Oligomer product was fractionated by distillation in vacuum and each fraction was characterized using viscometry, HNMR and GPC techniques. Analyses results showed that the fractions with higher boiling point and molecular weights had lower aromatic contents and higher viscosity index (VI).
