One of the most common applications is the chloralkali process.

Explanation:

Chloralkali process involves the formation of caustic soda and vinyl polymer (PVC) by the process of electrolysis of brine (salt water).

Electrolysis of brine or salt water (sodium chloride and water) generates chlorine gas and sodium hydroxide solution.

The sodium hydroxide solution can be concentrated up by removing some of the water, to create 50% NaOH, or caustic soda, which has many applications in the chemical and allied industries.

The chlorine is drawn off, and reacted with ethylene to create 1,2-dichloroethane, or Ethylene Dichloride. This is converted into vinyl chloride monomer (VCM) by thermal cracking, and the vinyl chloride monomer is reacted to form polyvinyl chloride (PVC), which is used to fabricate all kinds of things (window and door frames, pipes, parts of cars, wire and cable insulation, building insulation, etc. etc.)
