Oligomerization of low-molecular-weight olefins in ambient temperature molten salts

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]...

Description
Summary: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.
