碳酸氢钾KHCO3 98.5%

Property:Potassium Bicarbonate is colorless and transparent crystal. The relativedensity is 2.17. It is stable in the air. It is soluble in water, forming aslightly alkaline solution, but insoluble in alcohol. The solution can notreact with magnesium salt yielding precipitate of alkaline salt. It begins todecompose at 100°Cand completely decomposes and turns into Potassium Carbonate losing carbondioxide and water at 200°C.CAS RN:298-14-6Specification: Technical Grade QWH-J02-02-92INSPECTIONITEMUNITSTANDARDPurity% Min98.5Moisture% Max0.5PH valueMax8.8Iron% Max0.002Chloride(asKCL)%Max0.05Appearance-whiteSpecification:Fine GradeINSPECTIONITEMUNITSTANDARDPurity%Min99.0Chloride(asKCL)% Max0.02Sulphide(asK2SO4)% Max0.03Iron% Max0.001Insolublematter in water% Max0.02Moisture% Max0.5AppearancewhitePacking:Plastic woven bag or kraft paper bag inner with plastic bag, in 25/50kg net.Handling and Storage:Store in dry and ventilated house away from moisture.
