【Abstract】 The study improved the technical route for manufacturing potassium dihydrogen phosphate from potassium chloride and phosphoric acid . Optimum conditions were determined for the process. Potassium dihydrogen phosphate crystals can be obtained at room temperature by a single reaction.The process has such good features as higherpurity of the product,and lower energy consumption.Therefore,it is expected to be one of the moot economical processes with which the products could be produced industrially on a large scale.\;更多还原
