Barium chloride can be used to remove radium from mine water, making it safe for release into the environment. The process involves the addition of barium chloride to the water, which causes the radium to react and form insoluble barium-radium compounds.

These compounds can then be removed from the water through sedimentation or filtration.

Use in Caustic Chlorine Plants

Barium chloride is also used in caustic chlorine plants for brine purification. Brine is a solution of salt in water that is used to produce chlorine gas, caustic soda, and other chemicals.

It is essential to purify brine before using it in the production process to avoid contamination and improve efficiency. Barium chloride is added to the brine, which reacts with impurities and forms insoluble compounds, allowing them to be removed through sedimentation or filtration.

This process improves the quality of the brine and increases the efficiency of the process.

Barium Chloride in Synthetic Chemical Industry

Synthesis of Oil-Based Lubricants

The petroleum industry uses barium chloride in the synthesis of oil-based lubricants. The lubricants produced are chemically stable and can withstand high pressure and temperature, making them ideal for use in machinery and equipment.

Barium chloride acts as a catalyst in the synthesis of these lubricants. The process involves the reaction of barium oxide with long-chain hydrocarbons to produce barium long-chain alkyl sulfonate, which is used as a detergent in lubricants.

The lubricants produced using barium chloride are superior to those produced using other catalysts in terms of performance and stability.

Synthesis of Heat Treatment Salts

Barium chloride is also used in the paint industry for the synthesis of heat treatment salts. Heat treatment salts are used to harden steel components in a process known as quenching.

Barium chloride acts as a raw material in the production of these salts. The process involves the reaction of barium chloride with sulfuric acid to produce barium sulfate and hydrochloric acid.

The hydrochloric acid is then reacted with sodium chloride to produce sodium chloride hydrochloric acid. This solution can be used as a heat treatment salt for hardening steel components.
