Dipotassium phosphate-Dipotassium phosphate-Dipotassium-DKP CAS No.: 7778-77-0 HS Code: 2835240000103 EINECS No.: 231-834-5 Chemistformula: K2HPO4, K2HPO4.3H2O Molecular weight: 174.18, 228.22 Standard of execution (Standard): HG/T4510-2013 (IG), GB25561-2010 (FG) Characteristics: white crystalline or amorphous white powder, soluble in water, water solution is slightly alkaline, slightly soluble in alcohol, moisture absorption, high temperature self-soluble. The relative density is 2.338, and the internal dewatering of the molecules is converted into potassium pyrophosphate at a relative density of 204 degrees C. The pH of 1% aqueous solution is about 9. Properties: white crystal or formless powder. It is soluble in water easily, slightly soluble in alcohol. Strong absorption of moisture. When anhydrous product temperature to 204 degrees C. It will be dehydrated into intosium pasium pyrophosphate. The PH of 1% aqueous solution is about 9.

It is the raw material for the manufacture of potassium pyrophosphate and is used for boiler water treatment. Used as a buffer in chemical analysis for phosphating treatment of metals and as an electroplating additive. Potassium phosphate regulator for the corrosion inhibitor fermentation industry. For medicine (penicillin, streptomycin culture agents) industry, microorganisms, bacteria culture agents, antibiotic media nutrients. It can also be used as an iron-stripping agent, pH regulator, etc. for talcum powder. The food industry is used as raw materials, fermentation agents, flavorings, puffers, mild alkalines of dairy products, yeast food ingredients, which are sometimes added to milk tea powder. It can also be used as a feed additive. Uses: Fertilizer: Used as a high efficient, K and P compound water de be fertilizer, also as a basic raw raw for NPK fertilizers. The raw material for producing potassium pyrophosphate. Food Industry: Used as additive in the coffee creamers substitute and as-far in-all powdered materials (agler (emulsifier) in non-dairy creamers, bodybuilding drinks. For the for the ethifof of the pasta with with alkaline materials, the sing, the agent, the agent, the leavening agent, the leavening agent, the mild agent, yeast starter, the eddy as buffering agent. Also used as feed additives. Pharmaceutical Industry: Used as a singin in the culture of the culture to produce antibiotics, animalcule, Bacteria culture and as a in certain pharmaceuticals. Also be used as talc iron removal agent, pH regulator. General: Put antifreeze solutions as a buffer and sequestrate. Used in boiler water treatment. Easy as a buffer in chemical analysis, as a phosphating treatment of metals and as an electroplating additive.
