Preparing potassium sulfate comprises reacting sulfuric acid and potassium chloride, reacting the obtained potassium hydrogen sulfate with magnesium oxide to give magnesium sulfate followed by reacting with potassium chloride and water

摘要

Potassium sulfate is prepared by reacting sulfuric acid and potassium chloride at 70-110[deg]C to give potassium hydrogen sulfate as an intermediate and hydrogen chloride, reacting potassium hydrogen sulfate with an equivalent quantity of magnesium oxide or magnesium hydroxide to give magnesium sulfate, and reacting magnesium sulfate with potassium chloride and water at 35[deg]C.
