Calcium Chloride Drying Agent

Calcium Chloride Drying Agent

A drying agent is a chemical used to remove water from an organic compound that is in solution.Used as a desiccant for drying gases and liquid hydrocarbons within many industries due to its high affinity and capacity for absorbing water.

Why calcium chloride can be as an drying agent/desiccant?

Calcium chloride (CaCl2) is a white powder, granule, flake. Due to its certain characteristics of calcium ions, it can be combined with some water to form crystal water CaCl2·nH2O, n=1,2,4,6 Calcium chloride (CaCl2) has a high solubility in water. 100 °g of water can dissolve 59.5 g of calcium chloride at 0 ° C, and 100 g of water can dissolve 159 g of calcium chloride at 100 ° C. It can form hydrates containing 1, 2, 4, and 6 crystal waters, and their temperature ranges are: CaCl2•6H2O is lower than 29°C; CaCl2•4H2O, 29~45°C; CaCl2•2H2O, 45~175°C; CaCl2•H2O, above 200 °C. The great solubility of calcium chloride determines its ability to absorb moisture (drying) in a solid state and is not easily reacted with other substances, so CaCl2 can be used as a calcium chloride desiccant.

Calcium Chloride Desiccant (CaCl2) Application: Suitable for drying of hydrocarbons, olefins, acetone, ethers and neutral gases.

Calcium chloride desiccant (CaCl2) can not be dried: it forms complexes with alcohols, phenols, amines, amides and some aldehydes and ketones, so it can not be used to dry these compounds. Its industrial products may contain alkaline substances, so they cannot be used. To dry the acid.

Calcium chloride desiccant is the desiccant with the highest moisture absorption rate on the market. It is not only safe and environmentally friendly, but also contains no DMF. It is made of green, non-toxic and harmless calcium chloride and food grade adhesive. Calcium chloride fully meets the requirements of FDA, EPA, EFSA and other food applications, 100% without DMF.

Calcium chloride is particularly suited for use as a desiccant because of its hygroscopic qualities. Substances that have these qualities work to induce or to sustain a condition of dryness in a local vicinity, which is typically a sealed container.

In its most common application, calcium chloride drying agent comes in solid form, and works as an absorbent. Other types of desiccants commonly used for specialized purposes may come in liquid or gaseous form as well. These types of desiccants commonly work via other processes, such as by chemically bonding the molecules in water.
