Abstract:The purification of manufacturing potassium dihydrogen phosphate (KH 2PO 4) by double decomposition with potassium chloride and wet process phosphoric acid purified by means of recycled melamine (C 3N 6H 6) were studied.The experimental results showed that the ratio of purification was different from stage to stage.The qualities of product KH 2PO 4 met the terms of code HG2321-92.
Keywords:wet  process phosphoric acid  purification  potassium dihydrogen phosphate  crystallization of melamine phosphate
