A process for producing hypophosphorous acid (H 3 PO 2) by reacting, in the absence of a catalyst and under an acidic condition, phosphine with an aqueous solution of hydrogen peroxide to produce an acid solution.The acid solution is then contacted with an non-transition metal hydroxide, oxide or carbonate, e.g. From time to time, however, it is recommended that this analysis for sodium hypophosphite be done independently to assure the bath is at its optimum concentration. According to traditional treatment PH 3 is converted to H 3PO 4, which is economically wasteful and may even cause pollution. Sodium Hypophosphite Material Safety Data Sheet (MSDS) Download MSDS. The process consists of several basic stages, as follows: preparation of initial components for SH synthesis and their supply to main reactor (R-4); synthesis of sodium hypophosphite; separation of sodium hypophosphite as the end product (R-6); heat energy supply and cooling , .The aim of preparation stage is to make NaOH–Ca(OH) 2 suspension and to prepare phosphorous-containing sludge. Useful Links. Depending on criteria, EN baths will normally last from 4–10 MTOs before their performance degrades beyond acceptable limits and the bath must be discarded.
