1、Chemical Name: Potassium Carbonate
2、Molecular Formula: K₂CO₃
3、Molecular Weight: 138.21
4、CAS: 584-08-7
5、Character: It is a white granular powder that crystallizes into small white translucent crystal particles. Odorless, with a strong alkali smell. It absorbs moisture easily in wet air. Soluble in water, aqueous solution is alkaline. Insoluble in ethanol and ether.
6、Usage: It is used as pH regulator, nutrient, processing aid and spice. When added into noodle and wonton processing properly, it could endow the product with unique flavor, color and resilience (Often combined with sodium carbonate, etc.). It is also used in mineral drinks.
7、Packing: It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.
8、Storage and Transport: It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substances.
