Brief Overview

 

Calcium Chloride was first discovered by an English chemist, Sir Humphrey Davy (1778-1829) in 1808. The compound has the formula CaCl2 and it is a deliquescent salt that occurs in seawater. It is also known as the common salt and it is crystalline, lumpy, or flaky in nature. CaCl2 exists in many forms such as dehydrate, monohydrate and hexahydrate forms.

 

Manufacturing Process

 

There are several methods to manufacture calcium chloride:

 

Method 1: Solvay Process: High purity limestone is reacted with salt brine to produce soda ash and calcium chloride according to the chemical equation below

CaCO3 + 2NaCl ---> Na2CO3 + CaCl2

 

Method 2: Reaction of HCl and Limestone (or other source of Calcium) to produce large quantities of CaCl2.

Food Industry

 

  • Used as a sequestrant and firming agent with E509.
  • Commonly used as an electrolyte in sports drinks, for canned vegetables and firming soybean curbs into tofu. Additionally, it is used to flavour pickles because of its extremely salty taste.
  • In brewing beer, calcium chloride is sometimes used to correct mineral deficiencies in the brewing water.

 

Chemical Industry:

 

  • Commonly used in industrial production and laboratories as a dehydrating and drying agent
  • Mainly used to dry gases (nitrogen, oxygen, hydrogen etc.)
  • Also used as a dehydrating agent in the production of alcohols, esters, ethers and acrylic resins.

 

Other Applications:

 

  • Used to remove ink in waste paper processing.
  • Used as a sizing agent and fire retardant in textile production, as well as a fog-clearing agent in harbors, dust collector for roads etc.
  • Used as a precipitant in producing lake coloured pigments.
