potassium dihydrogen phosphate cas no.778-77-0 molecular formula KH2PO4 purity 96% 98% package 27kg plastic woven bag appearancepower EINECS Number: 231-913-4Molecular formula structure or KH2PO4Molecular weight or atomic weight 136.09Density: 2.338Melting point 252.6Physical and chemical properties: colorless crystals or white crystalline Quartet powder. The relative density of 2.338. Melting point 252.6 . Soluble in water (90 when 83.5g/100ml water), acidic aqueous solution, 1% potassium dihydrogen phosphate solution pH value of 4.6. Not soluble in alcohol. There deliquescence. Heated to 400 , melting formed a transparent liquid, after cooling partial curing of opaque glassy potassium phosphate.Uses: industry as a buffer to develop agents; agriculture as a high phosphorus and potassium fertilizer; food-grade improvements as a food additive Preparation or source(1) from the appropriate role of the proportion of phosphoric acid and potassium carbonate derived. (2) slowly adding calculated amount of potassium hydroxide solution in phosphate occurred and in the reaction of potassium dihydrogen phosphate solution, and then by bleaching, filtration, concentration, cooling, precipitated crystals, and then centrifugal separation, drying was finished.Specifications Industrial grade: in line with HG2321-92; Food Grade: Meet FCC • 1981; Packing 25Kg, plastic woven bag;Purposes: Technical Requirements:
