Abstract
Poly-alpha-olefin (PAO) was researched over acidic ionic liquid catalyzed the oligomerization of 1-decene. Ionic liquid used was 1-butyl-3-methyl imidazolium as a cation and aluminum chloride as an anion, which could effectively catalyze oligomerization and had a higher selectivity. The optimum process conditions for the synthesis of PAO were that the reaction temperature was 160°C, the reaction time was 3 h, the mole ratio between AlCl3 and [Bmim]Cl was 2.5:1, and the count of catalyst was 3 wt%. The components of product were analyzed with gas chromatograph, and the test results showed that the conversion of 1-decene was 74%. The product was the mixture of dimer, trimer, tetramer, and pentamer.
