NaOH Inorganic raw material sodium hydroxide in different forms and purities
Product Introduction:
Sodium hydroxide, with the chemical formula NaOH, commonly known as caustic soda, caustic soda, or caustic soda, is a highly corrosive strong alkali that is generally in the form of flakes or particles. It is easily soluble in water (releases heat when dissolved in water) and forms an alkaline solution. It also has deliquescence, which makes it easy to absorb water vapor (deliquescence) and carbon dioxide (deterioration) from the air.
NaOH is one of the essential chemicals in chemical laboratories and is also a common chemical product. Pure product is a colorless and transparent crystal. Density 2.130g/cm ³. Melting point 318.4 ℃. Boiling point 1390 ℃. Industrial products contain small amounts of sodium chloride and sodium carbonate, which are white opaque crystals. There are block shaped, flake shaped, granular, and rod-shaped forms. Sodium hydroxide with a formula of 40.01 can be used as an alkaline cleaning agent in water treatment. It is soluble in ethanol and glycerol, but insoluble in propanol . It also has a corrosive effect on carbon sodium at high temperatures. It undergoes disproportionation reaction with halogens such as chlorine, bromine, iodine, etc., and neutralizes with acids to generate salts and water.

Product Usage:
Sodium hydroxide (NaOH) has a wide range of applications. Used for papermaking, soap, dyes, artificial silk, aluminum production, petroleum refining, cotton fabric finishing, purification of coal tar products, as well as food processing, wood processing, and machinery industry.
1.chemical experiment
Can be used for chemical experiments. In addition to being used as a reagent, due to its strong water absorption and deliquescence, it can also be used as an alkaline desiccant (unlike concentrated sulfuric acid, sodium hydroxide can only be used as a desiccant in the solid state and can only dry non acidic gases). It can also absorb acidic gases (such as in experiments where sulfur burns in oxygen, sodium hydroxide solution can be bottled to absorb toxic sulfur dioxide)
2.Industrial aspect
Sodium hydroxide is widely used in the national economy, and many industrial sectors require it. The department that uses sodium hydroxide the most is the manufacturing of chemical drugs, followed by papermaking, aluminum refining, tungsten refining, artificial silk, artificial cotton, and soap manufacturing. In addition, in the production of dyes, plastics, pharmaceuticals, and organic intermediates, the regeneration of old rubber, the electrolysis of metal sodium and water, and the production of inorganic salts, a large amount of caustic soda is also used to produce borax, chromium salts, manganese salts, phosphates, etc.
3.chemical industry
The characteristics of sodium hydroxide determine that this product is an indispensable and important substance in a large number of chemical reactions. Sodium hydroxide is one of the important raw materials for the production of polycarbonate, superabsorbent polymers, zeolites, epoxy resins, sodium phosphate, sodium sulfite, and a large amount of sodium salts.
4.papermaking
Sodium hydroxide plays an important role in the paper industry. Due to its alkaline nature, it is used in the process of boiling and bleaching paper pages.
5.food industry
Sodium hydroxide can be widely used in the following production processes: container cleaning process; The processing of starch; The preparation process of carboxymethyl cellulose; The manufacturing process of monosodium glutamate.
6.water treatment
Sodium hydroxide is widely used in water treatment. In sewage treatment plants, sodium hydroxide can reduce the hardness of water through neutralization reaction. In the industrial field, it is a rejuvenator for ion exchange resin regeneration. Sodium hydroxide has strong alkalinity and relatively high solubility in water. Due to the relatively high solubility of sodium hydroxide in water, it is easy to measure the dosage and is conveniently used in various fields of water treatment.
7.Artificial fibers and textiles
In the textile industry, sodium hydroxide is used for the final treatment and dyeing of fibers. Main application: Mercerization treatment for synthetic fibers
8.Aluminum smelting
Sodium hydroxide is used to process bauxite, which contains alumina, which is the raw material for producing aluminum (aluminum is the second most commonly used metal in the world). Sodium hydroxide is also used in the production of zinc alloys and zinc ingots.
9.Washing supplies
Sodium hydroxide has always been used for traditional household purposes. Until today, the demand for caustic soda for soap, soap, and other types of washing products still accounts for about 15% of caustic soda.
Soap: Making soap is the oldest and most widespread use of caustic soda, which is used to neutralize fatty acids during the soap making process.
Detergent: Sodium hydroxide is used to produce various detergents, and even today's laundry detergent is made from a large amount of caustic soda, which is used to neutralize excess fuming sulfuric acid after sulfurization reaction.
Bordeaux and copper sulfate are the main components of Bordeaux mixture.
