Quick Details
Specifications
Appearance is white crystalline or amorphous white powder, soluble in water, aqueous solution is slightly alkaline, slightly soluble in alcohol, has the water absorbability, high temperature autolysis. Relative density 2.338, 204 ℃ when the molecular internal dehydration into potassium pyrophosphate. 1% aqueous solution of the pH value of 8.9.
White crystalline or amorphous powder. Soluble in water, aqueous solution is slightly alkaline. Slightly soluble in alcohol. Has the water absorbability. After burning into pyrophosphate.
White crystalline or amorphous powder. Soluble in water, aqueous solution is slightly alkaline. Slightly soluble in alcohol. Has the water absorbability. After burning into pyrophosphate. 3 quality standard Enterprise standard Q/HG The molecular weight of 228.22 The rate of consumption neutralization 85% phosphoric acid (H3PO4) 0.561 Potassium hydrogen phosphate Caustic potash (92% KOH) 0.594
Solid caustic potash match into 30% aqueous solution, the clarification, filter to remove impurities, join the corrosion reaction tank after measurement, in just the right amount of 50% phosphoric acid solution, mix slowly in 90 ~ 100 ℃ under the neutralization reaction, reaction end point control pH8.5 ~ 9.0 (using phenolphthalein as indicator is red just so far). Heating to 120 ~ 124 ℃ for enrichment, meet the requirements to solution concentration range after filtration to remove insoluble substance.
