Potassium Hydrogencarbonate

Potassium Hydrogencarbonate, CAS number is 298-14-6, molecular formula is CH₂O₃·K, molecular weight is 100.114, used for the production of potassium carbonate, potassium acetate, arsenic Potassium acid and other raw materials are also used in medicine, food, fire extinguishing agent and other industries.

Basic Information

Storage method

1. Store in a ventilated and dry warehouse.It should not be stored in the shed or in the open air.Should pay attention to moisture.

2. When transporting, loading and unloading, it should be protected from rain to ensure that it is dry and the packaging is not damaged and polluted.Do not store and transport with acids.

3. In case of fire, water, sand and various fire extinguishers can be used to put out the fire.

The main purpose

1. It is used as raw material for the production of potassium carbonate, potassium acetate, potassium arsenite, etc. It is also used in medicine, food, fire extinguishing agent and other industries.As acidity regulator and chemical leavening agent, my country stipulates that it can be used in all kinds of foods that need to be added with leavening agent, and can be used in moderation according to production needs.It is the raw material for the production of potassium carbonate, potassium acetate and potassium arsenite.Can be used as a fire extinguishing agent for petroleum and chemicals.It can also be used in medicine and baking powder.As acidity regulator and chemical leavening agent, my country stipulates that it can be used in all kinds of foods that need to be added with leavening agent, and can be used in moderation according to production needs.

2. Supplement potassium for the diagnosis and treatment of hypokalemia.

3. Used as alkaline agent, leavening agent, nutritional supplement, excipient and pH regulator.GB2760-90, can be used as processing aid.Can be used for soft drinks, baked goods, etc.

4. Used as an analytical reagent.foaming agent.

Properties and Stability

1. No special combustion characteristics.

2. Stable in air, decomposed when heated to 100-120℃.

It is completely decomposed at 200 ° C and loses carbon dioxide and water to form potassium carbonate.Insoluble in ethanol.At 0°C, the solubility in 100g of water is 22.4g; at 60°C, 100g of water can dissolve 60g of potassium bicarbonate.Its aqueous solution is weakly alkaline, and it will lose CO2 if it is placed for a long time. When it is boiled, it will become an aqueous potassium carbonate solution.In air, the crystals are stable and decompose when heated to 100°C, converting to potassium carbonate.
