Pemasok yang Diaudit Chemical Name: Dextrose Anhydrous
Potassium carbonate has anhydrous or crystalline product containing 1.5 molecules. Anhydrous is white granular powder, crystalline product is white translucent small crystals or granules, odorless, with strong alkaline smell, relative density 2.428 (19ºC), melting point 891ºC, solubility in water is 114.5g/l00mL (25ºC) ), easy to absorb moisture and deliquescence in humid air. Dissolved in 1mL of water (25ºC) and about 0.7mL of boiling water, after the saturated aqueous solution is cooled, a glassy monoclinic crystal hydrate is precipitated, the relative density is 2.043, the crystal water is lost at 100ºC, the pH value of 10% aqueous solution is about 11.6, insoluble in ethanol and ether.

Potassium carbonate can be used in glass, printing and dyeing, soap, enamel, preparation of potassium salt, ammonia decarbonylation, also used in color TV industry, mainly used in food as leavening agent.
It is mainly used to analyze reagents. Such as high purity analysis, emission spectrum analysis. Can also be used for silicate and insoluble sulfate flux, organic liquid absorbent and electroplating, fertilizer, photography industry.
Used for glass, printing and dyeing, soap, enamel, preparation of potassium salt, ammonia decarbonylation, color TV industry, food as leavening agent; As gas adsorbent, dry powder fire extinguishing agent, rubber antioxidant, etc. Used for rinsing and processing exposed photosensitive materials.
It is used in the manufacture of the glass shell of the picture tube in the electronic industry, the decarbonization of fertilizer production, the manufacture of potassium salt, the analytical reagent, the flux, and the preparation of various potassium salts; Used for analysis of reagents, reference reagents and fluxes for molten silicates and insoluble sulfates.
Desiccant in chemical experiments. Its water absorption capacity is moderate, can form with two crystallized water potassium carbonate (K2CO3·2H2O), but the interaction with water is slow. Suitable for dry alcohols, esters and other neutral organic matter and general alkaline organic matter such as amine, alkaloid and so on. But can not be used as acids, phenols or other acidic substances desiccant.
Alkaline agent and dough improver, and can inhibit the acid of noodles, can be used for noodle food, according to the production needs of appropriate use. Used to produce optical glass, can improve the glass transparency, strength and refraction coefficient.
