Multi-functional ionic liquid compositions for overcoming polymorphism and imparting improved properties for active pharmaceutical, biological, nutritional, and energetic ingredients

A method for preparing an ionic liquid, comprising:

• a. providing cations and anions, or providing cation precursors and anion precursors, the cation or cation precursor is an herbicidal active selected from the group consisting of carfentrazone, imazapyr, benefin, flumetsulam, metosulam, ametryne, atrazine, cyanazine, diuron, hexazinone, metribuzin, pyridate, terbuthylazine, fluoroxypyr, fenoxaprop-P-ethyl, dimethenamid, flufenacet, mefenacet, metolachlor, S-metolachlor, thenylchlor, fluthiacet-methyl, carfentrazone-ethyl, isoxaflutole, 4-(4-trifluoromethyl-2-methylsulfonylbenzoyl)-5-hydroxy-1-methyl-3-methylpyrazole, glyphosate, pendimethalin, trifluralin, and triaziflam, or an ionic derivative thereof;
• and the anion or anion precursor is selected from the group consisting of halide, sulfate, carbonate, bicarbonate, phosphate, nitrate, nitrite, acetate, PF6−, BF4−, triflate, nonaflate, bis(triflyl)amide, trifluoroacetate, heptafluororobutanoate, and haloaluminate
• b. combining the cations and anions or the cation precursors and anion precursors, thereby producing an ionic liquid that is liquid at a temperature of from about −30° C. to about 125° C.
