[Abstract]:The effects of reaction temperature, molar ratio of raw materials, time and mass fraction of sulfuric acid on the product of potassium hydrogen sulfate in anhydrous phase were discussed. Through the single factor experiment, the orthogonal experiment shows that the optimum technological conditions for the preparation of potassium hydrogen sulfate by the reaction of industrial concentrated sulfuric acid with potassium chloride are at 80 鈩，
