Method to make an acid catalyst having greater than 20 wt% conjunct polymer
Abstract
A method to make an acidic ionic liquid catalyst, by mixing aluminum chloride in the presence of a hydrocarbon solvent, an organic chloride, and optionally an ionic liquid; wherein the acidic ionic liquid catalyst does not precipitate out solids; and wherein the acidic ionic liquid catalyst has greater than 20 wt % conjunct polymer and a molar ratio of Al to a heteroatom selected from the group consisting of N, P, O, S, and combinations thereof greater than 2.0. Also a method to make the acidic ionic liquid catalyst comprising: a. mixing aluminum chloride in the presence of a hydrocarbon solvent, and an organic chloride, to make an acid catalyst phase comprising a conjunct polymer; b. adding hydrogen chloride to the acid catalyst phase.
