Abstract
THIS INVENTION RELATES TO A PROCESS FOR THE ALKYLATION OF AROMATICS BY REACTING AN AROMATIC HYDROCARBON WITH AN OLEFIN IN THE PRESENCE OF AN IONIC LIQUID COMPRISING (A)A COMPOUND OF THE FORMULA RNMX3-N WHEREIN R IS A C1-C6 ALKYL RADICAL, M IS ALUMINIUM OR GALLIUM, X IS A HALOGEN ATOM AND N IS 0, LOR 2 AND, (B) A HYDROCARBYL SUBSTITUTED IMIDAZOLIUM HALIDE OR A HYDROCARBYL SUBSTITUTED PYRIDINIUM HALIDE WHEREIN AT LEAST ONE OF THE SAID HYDROCARBYL SUBSTITUENTS IN THE IMIDAZOLIUM HALIDE IS AN ALKYL GROUP HAVING 1-18 CARBON ATOMS. THE PROCESS ALLOWS READY SEPARATION OF REACTION PRODUCTS FROM THE IONIC LIQUID AND IMPROVES SELECTIVITY TO ALKYLATED PRODUCTS.
