ABSTRACT:
An electrodialytic distillative process for recovery of anhydrous hydrogen fluoride from an aqueous solution of fluosilicic acid and hydrogen fluoride wherein the concentration of hydrogen fluoride in said solution is such that hydrogen fluoride cannot be recovered therefrom by distillation, which comprises subjecting the solution to electrodialysis thereby increasing the total acids concentration in said solution to equal to or greater than about 46 weight percent, and thereafter recovering anhydrous hydrogen fluoride by distillation.
