Study on the Preparation of Sodium Sulfate-Hydrogen Peroxide-Sodium Chloride Adduct

A new stable cyclic process for preparation of sodium sulphate-hydrogen peroxide-sodium chloride adduct was proposed in this paper. After a small amount of mother liquid was removed, calculated amount of sodium sulfate,sodium chloride and hydrogen peroxide of high concentration was added to the mother liquid. The components of mother liquid, amount of solid product and its hydrogen peroxide content are approximately the same in five cycles. In the stable cyclic process, the mother liquid was utilized sufficiently. The product was placed in dry oven and the temperature was kept at 423K for 3 hours. Decomposition fraction of the product for each cycle was less than 2.3%,so the product was of high stability.
