Abstract
Process in which double potassium-ammonium sulfate is produced from potassium chloride and sulfuric acid was studied. A thermal analysis of the compound KNH4SO4 was made and the melting and decomposition points of double potassium-ammonium sulfate were determined. An X-ray phase analysis revealed the processes occurring when double potassium-ammonium sulfate is calcined at temperatures of 330, 370, and 580°C. The chemical processes in which double potassium-ammonium sulfate decomposes to give ammonium hydrosulfate were examined.
