Product Description Sodium Hydroxide (NaOH) Product Description1. Product OverviewSodium Hydroxide, also known as caustic soda or lye, is an inorganic compound with the chemical formula NaOH. It is a highly caustic alkali that is widely used in numerous industries. Sodium hydroxide appears as white solid pellets, flakes, or granules, and is readily soluble in water with strong exothermic reactions, producing an alkaline solution. It is odorless, highly hygroscopic, and possesses strong alkalinity, making it one of the most important basic chemicals in industrial production.Common names include Caustic Soda, Lye, Sodium Hydrate, and Caustic Alkali. It is classified under CAS No. 1310-73-2 and has a molecular weight of 39.997 g/mol.2.

It reacts with amphoteric metals like aluminum and zinc, releasing h-ydrogen gas. It also absorbs moisture and carbon dioxide from the air, forming sodium carbonate over time. 3. Manufacturing ProcessThe most common industrial methods for producing sodium hydroxide include:Membrane Cell Process: Produces high-purity sodium hydroxide by electrolysis of sodium chloride solution using ion-exchange membranes. This method is energy-efficient and environmentally friendly.Diaphragm Cell Process: Uses a porous diaphragm to separate the anode and cathode chambers, producing sodium hydroxide with slightly lower purity but lower production costs.M-e-r-cury Cell Process: Now largely phased out due to environmental concerns, this method used m-e-r-cury cathodes to produce high-purity caustic soda.In all cases, the by-products include c-hlorine gas and h-ydrogen gas, which are often utilized in other industrial applications.4.
