TH18485A - Method for making hypophosphorous acid - Google Patents

Abstract

The revealing is a method of making hypophosphorous acid from sodium. Hypophosphite by Phapha-dihydrated water separation action of each substance The aqueous flakes of sodium hypophosphite can be incorporated into the Existing processes for producing sodium Hypophosphite, which is used to manufacture products of sodium processes. Hypophosphite as a starting material In the process of hypophosphorus acid and Dissolve sodium, less hypophosphite from hypophosphite acid treatment, which contains some hypophosphorus acid, used to adjust PH in sodium hypophosphite process.

Claims (2)

1.Method for making hypophosphorous acid and sodium. Hydroxide from sodium hypophosphite, which consists of a dewatering action That diallized with electricity to the aqueous solution of the said sodium hypophosphite. 2. Method according to claim 1, which is performed to separate the water that has been alized With such electricity in the cell Structured electrolyte Anode-A-AM- [S-CM-B-BM-A-AM] n-S-CM-B-cathode, where CM is the cation exchange membrane, B is the base part with aqueous solution. Of the sodium hydroxide product, BM is the exchange membrane. The bipolar ion, A is the tag:
