ABSTRACT:
Disclosed is a method of making hypophosphorous acid from sodium hypophosphite by performing electrodialytic water splitting upon an aqueous solution of sodium hypophosphite. The process can be tied into an existing process for producing sodium hypophosphite wherein the product of the sodium hypophosphite process is used as a starting material in the hypophosphorous acid process and the depleted sodium hypophosphite solution from the hypophosphorous acid process, which contains some hypophosphorous acid, is used to adjust the pH in the sodium hypophosphite process.
