Oligomerization of hexene-1 in the presence of catalytic systems on the basis of ionic liquids

Abstract

The results of hexene-1 oligomerization in the presence of recyclable catalysts on the basis of chloroaluminate ionic liquids and in combination with Ti-containing complexes with “grafted ionic liquid” ligands are reported. The possibility has been shown of the selective preparation of products with an oligoalkylnaphthene structure with a narrow molecular mass distribution (M w/M n = 1.03−1.55) characterized by the absence of double bonds. It has been found that the molecular mass of oligomer products can be regulated by changing the molar ratio of the components of the catalytic system.
