Potassium Carbonate(Food Addictive Grade), CAS 584-08-7 CAS NO.584-08-7

properties:

potassium carbonate may be monoclinic crystal, white powder, granular crystal or round ball. the relative density is 2.428 and the melting point is at 891 degree. it is easily soluble in water forming. slightly alkaline solution. it is. insoluble in alcohol and ether. it has strong hygroscopicity. it easily cakes and turns into potassium bicarbonate through absorbing carbon dioxide when. exposed to the air for long time.

specification: industrial grade. (gb/t 1587-2000)

specification: food additive potassium carbonate(hg2452-93)

packing: plastic bag lined woven bag or paper-plastic laminated bag, net wt 25／50／1000 kg.

storage and transportation: stored in dry and ventilated house away from moisture. don't store in goods yards. or expose to the air. protect the material from rain when loading and unloading.. be sure to keep the package dry and free from contaminant. avoid handling and. transporting together with acid substances. in the event of fire, use water as extinguishing agent.

uses: potassium carbonate is used as raw material in manufacturing electro tube, tv kinescope, computer display. it is applied in optical glass improving clarity, strength and refractive index. it is also applied in electrode avoiding electric arc breaking-off during welding. it is used to produce food additives like potassium sorbate, monopotassium phosphate, etc. potassium carbonate is foliar spray fertilizer and. constituent of compound fertilizer. in dyeing industry, it is used to produce vat dyestuff and discharge of ice dyeing. it is absorbent removing hydrogen sulfide and carbon dioxide; dry powder extinguisher mixed with soda; auxiliary raw material for producing alcohol and acetone; and anti-aging agent in rubber production. its solution is used in boiling and scouring of cotton cloth and wool's degreasing. in addition, it is also used in manufacture of printing ink, photograph-drug, polyester, explosives, electroplating, tanning, ceramic, building materials, crystals and medicine. used in the production of instant noodles, additive of carbonated drinks, have leavening and anticorrosive effect. as material of food additive potassium sorbate potassium dihydrogen phosphate.
