摘　　要： 利用单因素优选法,研究了288K下用30％的过氧化氢制备硫酸钠—过氧化氢—氯化钠加合物时,氯化钠和硫酸钠的原料配比对产品产量及产品中过氧化氢质量分数的影响。结果表明,氯化钠和硫酸钠的最优质量配比为1:8。在25mL过氧化氢中加入4g NaCl,32g Na_2SO_4,此时产品产量为31.44g,产品中过氧化氢质量分数为9.5％～9.7％,产品颗粒较细。利用二元非线性回归得到了产品产量与硫酸钠和氯化钠加入量关系的数学模型,模型的计算结果与实验值吻合较好,最大偏差为5％。 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%.
