Sodium hydroxide (NaOH), also known as lye and caustic soda, is a caustic metallic base. It is used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents and as a drain cleaner.

Pure sodium hydroxide is a white solid available in pellets, flakes, granules, and as a 50% saturated solution. It is hygroscopic and readily absorbs carbon dioxide from the air, so it should be stored in an airtight container. It is very soluble in water with liberation of heat. It also dissolves in ethanol and methanol, though it exhibits lower solubility in these solvents than does potassium hydroxide. Molten sodium hydroxide is also a strong base, but the high temperature required limits applications. It is insoluble in ether and other non-polar solvents. A sodium hydroxide solution will leave a yellow stain on fabric and paper.

Uses:Caustic soda is used very widely in chemical experiments, in addition to used as reagent, because it has strong moisture absorption and deliquescence, also can be used as alkaline desiccant.


chemical industry

Caustic soda is the production of polycarbonate, super absorption polymer, zeolite, epoxy resin, sodium phosphate, sodium sulfite and sodium salt of one of the important raw materials.
pulp and paperCaustic soda in the papermaking industry plays an important role. Because of its basic characteristics, it is used in the process of boiling and bleaching sheet.
food industryCaustic soda can be widely used in the following production process: the container of the cleaning processes; Starch processing process; The preparation of carboxymethyl cellulose process; The manufacturing process of sodium glutamate.
water treatmentCaustic soda is widely used in water treatment. In the sewage treatment plant, the sodium hydroxide by neutralization reaction, reduce the water hardness. In the field of industry, is the regeneration of the ion exchange resin regeneration agent.
synthetic fibers and textilesIn the textile industry, caustic soda is used for final processing and fiber dyeing. Main use: fiber mercerization as a legal person.
metal technologyCaustic soda is used to deal with bauxite.
soap and washingMain use: soap: making soap is the oldest and most widely used caustic soda, in the process of manufacture of soap, caustic soda is used to neutralize fatty acids. Detergent: caustic soda is used to produce all kinds of detergent.
food preparationFood uses of caustic soda include washing or chemical peeling of fruits and vegetables, chocolate and cocoa processing, caramel coloring production, poultry scalding, soft drink processing, and thickening ice cream. Olives are often soaked in sodium hydroxide for softening; Pretzels and German lye rolls are glazed with a sodium hydroxide solution before baking to make them crisp
