Calcium Chloride
The Cost-Effective Choice for Your Drying Process |
Calcium chloride in its anhydrous form is an economical drying agent and very important for drying processes in laboratories. Those are for example: drying of liquids and neutral gases. It is also a very good drying agent for a wide variety of solvents.
Calcium chloride is suitable for drying acetone, ethers, numerous esters, aliphatic, olefinic, aromatic and halogenated hydrocarbons, and neutral gases. Since calcium chloride is also available in granular form, it is often used in drying tubes.
Note: Calcium chloride is not suitable for drying ammonia, amines, alcohols, phenols, aldehydes, ketones and some esters because these substances are bound by CaCl2.
Calcium chloride has a drying capacity up to 98%. It binds the water through crystallization and can be regenerated by warming. Regenerate at 250°C for at least 1 hour.
