1、Chemical Name: Potassium Bicarbonate
2、Molecular Formula: KHCO3
3、Molecular Weight: 100.11
4、CAS: 298-14-6
5、Character: It is colorless monoclinic crystal. The density is 2.17. It’s stable in air. It’s soluble in water with a very weak alkaline reaction. It’s hardly soluble in ethanol. It’ll decompose to Potassium Carbonate, water and Carbon Dioxide at 100-120 ℃.
6、Usage: In food industry, it is used to replace baking powder or yeast, and used to make pure Potassium Carbonate, etc. It’s also used as pH regulator, swelling agent and used in mineral beverage, infant formula powder and maternal formula powder.
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.
