Method to make an acidic ionic liquid catalyst having greater than 20 wt% conjunct polymer

Abstract

A method to make an 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.

What is claimed is: 
     
         1 . A method to make an acidic ionic liquid catalyst that is effective for catalyzing a reaction, comprising:
 a. mixing an 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 a hydrogen chloride to the acid catalyst phase to make the acidic ionic liquid catalyst;   wherein the acidic ionic liquid catalyst has greater than 20 wt % of the conjunct polymer and a molar ratio of a compound containing Al to a compound containing a heteroatom selected from the group consisting of N, P, O, S, and combinations thereof greater than 2.0.   
     
     
         2 . The method of  claim 1 , wherein an amount of the hydrogen chloride is adjusted to provide product selectivity to the reaction. 
     
     
         3 . The method of  claim 1 , wherein the acidic ionic liquid catalyst does not precipitate out solids. 
     
     
         4 . The method of  claim 1 , wherein the acidic ionic liquid catalyst comprises greater than 25 wt % of the conjunct polymer. 
     
     
         5 . The method of  claim 1 , wherein the molar ratio is 5 or greater. 
     
     
         6 . The method of  claim 5 , wherein the molar ratio is 10 to about 1000. 
     
     
         7 . The method of  claim 6 , wherein the molar ratio is greater than 1000. 
     
     
         8 . The method of  claim 1 , wherein the reaction is alkylation, isomerization, hydrocracking, polymerization, dimerization, oligomerization, acylation, acetylation, metathesis, copolymerization, dehalogenation, dehydration, olefin hydrogenation, or combinations thereof. 
     
     
         9 . The method of  claim 8 , wherein the reaction is isoparaffin/olefin alkylation. 
     
     
         10 . The method of  claim 1 , wherein the hydrocarbon solvent is isopentane. 
     
     
         11 . The method of  claim 1 , wherein the acidic ionic liquid catalyst has no heteroatom-containing compounds comprising N, S, O, or P.
