Disclosed are methods for making a phosphonium sulfonate salt of generic formula (1): wherein each X is independently a halogen or hydrogen, provided that the molar ratio of halogen to hydrogen is greater than- about 0.90; p is 0 or 1 and q and r are integers of 0 to about 7 provided that q+r is less than 8 and that if p is 1 then r is greater than zero; and each R is the same or different hydrocarbon radical containing 1 to about 18 carbon atoms.

A process that can be used for manufacturing a tetraalkylonium perfluoroalkylsulfonate is provided. The process comprises contacting a tetraalkylonium halide with a metal perfluoroalkyl sulfonate to produce a mixture; allowing the second mixture to produce an aqueous upper layer and a separate lower liquid layer; separating the lower liquid layer from the upper aqueous layers to produce a product layer; optionally washing the product layer with 1 to 10 volumes of water, based on the volume of the product layer at a temperature of about 50° C. to about 100° C. to produce a washed product layer; and drying the product layer or washed product.
