| Abstract: | Author introduces the production method of K2SO4 by KC1 and CaSO4 under existing condition of ammonia water. The experiment indicates that the optimal production conditions are: The granularity of calcium sulfate is more than 180 mesh, initial concentration of ammonia water is 36% - 40% , reaction temperature iso - 10 oC, time is 90 - 120min, moreover adding of potassium chloride is gradual, potassium sulfate with concentration of 99.1 % and 99.8 can be produced by one step method and two steps method. |
