The Preparation of Potassium Bisulfate and Ammonium Potassium Sulfate

论述了硫酸氢钾及硫酸钾铵的制备 ,硫酸和氯化钾反应得硫酸氢钾并释放HCl气体 ;硫酸氢钾和碳酸氢铵反应得硫酸钾铵和CO2 气体。HCl气制盐酸 ,CO2 气制液态二氧化碳。该工艺原料综合利用好 ,生产成本低 ,经济效益好。

The preparation of potassium bisulfate and ammonium potassium sulfate are described in the paper.Potassium bisulfate and HCl gas are produced by the reaction between sulfuric acid and potassium chloride.The ammonium potassium sulfate and CO 2 gas are preparated by the reaction between potassium bisulfate and ammonium bicarbonate.Hydrochloric acid and liguid carbon dioxide are manufactured respectively from HCl gas and CO 2 gas.The technology is characterized by good comprehensive utilization of the raw materials,low costs of production and high economic benefit.
