Desiccant Of Calcium Chloride

JIUXU INDUSTRIAL (HK) CO., LIMITED | Updated: May 02, 2018

Granular anhydrous calcium chloride is often used as a desiccant to fill the drying pipe. The dried kelp (or sea grass ash) with calcium chloride can be used for the production of soda ash. Some household dehumidifiers, such as DampRid, use calcium chloride to absorb moisture in the air. Calcium chloride can also be used as a drying agent or dehydrating agent for gases and organic liquids. As calcium chloride is neutral, it can dry acid or alkaline gases and organic liquids, and can also dry these gases in a small amount of gas such as nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide, carbon dioxide, nitrogen dioxide and so on. But it can not be used to dry ethanol and ammonia, because ethanol and ammonia react with calcium chloride to form alcohols CaCl2? 4C2H5OH and ammonia CaCl2? 8NH3 respectively. Anhydrous calcium chloride can also be used as an air hygroscopic agent for household products. Anhydrous calcium chloride as a absorbent has been approved by the FDA for first aid, and its role is to ensure the drying of the wound.

The anhydrous calcium chloride is spread on the sand and stone pavement, and the moisture absorption of the anhydrous calcium chloride is used to keep wet air in the air when the air humidity is below the dew point to keep the road surface moist, thus controlling the rise of the dust on the road.
