Sodium hydroxide is produced by electrolysis of sodium chloride (salt). In this process, the salt is electrolyzed in a water solution to produce sodium hydroxide and chlorine gas. The sodium hydroxide is then purified.
Areas of Use:
Chemical Industry: Sodium hydroxide is used in the production of many chemical products. It is also used in the production of soaps, detergents and cleaning products.
Water Treatment: Sodium hydroxide is used to adjust pH in water treatment plants.
Paper and Pulp Industry: It is used for bleaching in paper and cellulose production.
Oil Refineries: Oil refineries use sodium hydroxide for the extraction and processing of hydrocarbons.
Food Industry: Sodium hydroxide is used in the processing of some food products, especially to regulate components of foods such as molasses and cereals.
