Abstract: Disclosed are double salt ionic liquids that include at least one organic cation and at least two metal halide anions. Methods of making the double salt ionic liquids can include combining two or more metal halide containing salts, wherein the metal halide containing salts include at least one organic cation and at least two metal halide anions. The reaction between the two or more salts at any ratio allows fine tuning, rate of dissolution, solubility, and bioavailability of the double salt ionic liquids. The ionic liquids disclosed herein can be used as a catalyst for catalyzing a chemical reaction. The chemical reaction can be an acid catalyzed chemical reaction such as a Lewis acid catalyzed reaction, a Beckmann rearrangement reaction, a Meyer-Schuster rearrangement reaction, a heterocyclic synthesis, a reaction for biodiesel production, a mercury-catalyzed type reaction, or a hydrogen-fluoride catalyzed type reaction.
