摘  要:
Potassium dihydrogen phosphate as food additives,feed additives and efficient chlorine-free phosphorus and potassium compound fertilizer,and the market demand in our country is rising every year.Based on the improvement of the traditional mannheim technology of potassium sulfate,the new technology of potassium dihydrogen phosphate with potassium chloride and waste sulfuric acid as raw materials is developed.Compared with the traditional preparing technology of potassium dihydrogen phosphate,the new technology has characteristics of simple process,low cost,small investment,and higher resource utilization,the product can be applied in agriculture.
