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.
