Study on the synthesis of sodium sulphate-hydrogen peroxide-sodium chloride adduct (I)—Effect of the ratio of raw materials on the yield of the adduct

The influence of mass ratio of sodium chloride to sodium sulphate on the yield and mass fraction of H_2O_2 in the product is studied by single factor optimization with 30%H_2O_2 mass fraction solution at the temperature of 288K. It is concluded that the optimum mass ratio of sodium chloride to sodium sulphate isl : 8. The yield of the product is 31. 44g and the mass fraction of H_2O_2 in the product is 9.5%9.7% when adding 4g NaCI and 32g Na_2SO_4 to 25 mL 30~ H_2O_2 solution, and the product granule is fine. The mathematical model, which describes dependence of the yield on the adding mass of the sodium sulphate and sodium chloride, is obtained by bivariate non-linear regression, and the calculated results of the model are in good agreement with the experimental data and the maximum deviation is less than 5%.
