Formation of higher molecular weight hydrocarbons with relatively high yields has been achieved during the passage of low molecular weight olefins (ethylene, propylene) through low-temperature ionic melts. Three ionic melts were investigated: AlCl[sub 3]/ButPyrCl, AlCl[sub 3]/PyrHCl, and AlCl[sub 3]/ImCl. The main products of ethylene and propylene oligomerization were C[sub 3]-C[sub 6] hydrocarbons. Formation of higher products (C[sub >6]) was observed after prolonged operation. A tentative correlation between the acidic properties of the melts and their catalytic efficiency toward olefins oligomerization is proposed.
