    Physicochemical Property of Hypophosphorous acid liquid

    Hypophosphorous acid CAS 6303-21-5 is a reducing agent. Strong monoacid. The aqueous solution is acidic and can be gradually oxidized in air at room temperature. It will cause combustion when contacted with H-porous agent. Burns by intense reaction with oxidizing agent. By high heat decomposition of highly toxic phosphine gas, or even explosion. Hypophosphorous acid liquid is often added to cool drinks because it is not absorbed. So the danger is small, but especially concentrated hypophosphorous acid can harm the stomach and intestines. The solid acid is disproportionately decomposed to PH3 and H3PO4 when heated to 130-140°C. It is a fairly strong monoprotic acid (K=9×10-2).

    Hypophosphorous acid CAS 6303-21-5

    Colorless oily liquid or easily deliquescent crystals. Hypophosphorous acid Raw Materials is soluble in hot water, ethanol, ether. Soluble in cold water.

    production methodprocess of Hypophosphorous acid liquid

    Ion Exchange Resin MethodApproximately 70g of cation exchange resin moistened with water is loaded into a glass tube and circulated with 5mol/L hydrochloric acid for about 15min, and after sufficient water washing, an aqueous sodium hypophosphite solution with high purity (15g/60mlH2O) is flowed from it, and the column of the resin is first used for 50ml, and then rinsed with 25rnl distilled water. The effluent acid and washings were combined and concentrated by evaporation on a water bath. The concentrated acid was dehydrated in a high vacuum, dryer with P205, cooled and crystallized, filtered and recrystallized to produce Hypophosphorous acid Raw Materials.
