The properties and uses
of calcium chloride in the field of raw materials for chemical production
1. the properties of calcium chloride

calcium chloride is an inorganic compound with various properties. First of all, calcium chloride is a white crystalline powder with strong hygroscopicity and can absorb moisture in the air. Secondly, calcium chloride has good solubility and can be dissolved in organic solvents such as water, ethanol and acetone. In addition, calcium chloride also has good thermal stability, can be stable at high temperatures.

2. the use of calcium chloride

calcium chloride has a wide range of uses in the field of chemical production raw materials, mainly used in the following aspects:

1. desiccant

calcium chloride has strong hygroscopicity, can be used as a desiccant. In chemical production, it is often necessary to dry some gas or liquid to remove the moisture. Calcium chloride can be used as a desiccant to effectively absorb the moisture in it and achieve the purpose of drying.

2. Refrigerant

Calcium chloride can be used as a refrigerant. In some low temperature experiments, it is necessary to use a refrigerant to reduce the temperature. Calcium chloride has good thermal stability and can exist stably at low temperatures, so it can be used as a refrigerant.

3. Chemical raw material

Calcium chloride can be used as a chemical raw material for the production of some chemical products. For example, calcium chloride can react with sodium carbonate to produce calcium carbonate and sodium chloride, thereby producing chemical products such as soda ash and table salt.

4. food additive

calcium chloride can be used as a food additive, mainly used to adjust the taste and texture of food. For example, calcium chloride can be added to tofu to increase the hardness and elasticity of tofu and improve the taste.

In short, calcium chloride has a wide range of uses in the field of chemical production raw materials, and can be used as desiccants, refrigerants, chemical raw materials and food additives.
