Caustic Soda, chemically known as Sodium Hydroxide (NaOH) and commonly referred to as lye, is a highly caustic, white, crystalline, and odorless inorganic compound. It is water-soluble and forms a strong alkaline solution, but remains insoluble in ether and other non-polar solvents.
Recognized for its aggressive reactivity and corrosive properties, it decomposes proteins and organic materials on contact, making proper handling essential.
As detailed in Ullmann’s Encyclopedia of Industrial Chemistry, caustic soda is manufactured through the evaporation of sodium hydroxide solution to minimize water content. Efficient energy utilization is achieved using advanced multistage evaporation equipment.
Caustic Soda is a key raw material across a broad spectrum of industries. Common uses include:
Due to its corrosive and reactive nature, caustic soda must be handled with appropriate safety gear. Direct contact may result in severe chemical burns. Always consult the Safety Data Sheet (SDS) prior to handling.
