Sodium hydroxide (NaOH) is used in a wide range of applications. Used in the production of paper, soap and dyes, rayon, smelting metal, oil refining, cotton fabric finishing, the purification of coal tar products, as well as food processing, wood processing and machinery industry, etc.
The chemical experiment
It can be used for chemical experiments. In addition to being used as a reagent, it can also be used as an alkaline desiccant due to its strong water absorption and dampness.  acid gases can also be absorbed (for example, in the experiment of sulfur burning in oxygen, sodium hydroxide solution can be put into a bottle to absorb the toxic sulfur dioxide).
The neutral and alkaline gases are mixed with CO dissipation, which can be divided by NaOH, and can be generated by NaOH.
CO ₂ naoh + 2 = Na + H ₂ CO ₃ ₂ O; Nahco3 H2O + CO2 + Na2CO3 = 2
The chemical industry
Sodium hydroxide is widely used in the national economy and is needed in many industrial sectors. The sector that USES sodium hydroxide most is the manufacture of chemicals, followed by the manufacture of paper, aluminium, tungsten, rayon, rayon and soap. In addition, in the production of dyes, plastics, pharmaceutical and organic intermediates, old rubber regeneration, sodium metal, the electrolysis of water and inorganic salt production, producing borax, chromium salt, manganese acid salt, phosphate, etc., also want to use a large amount of caustic soda. Meanwhile, sodium hydroxide is one of the important raw materials for the production of polycarbonate, super absorbent polymer, zeolite, epoxy resin, sodium phosphate, sodium sulfite and a lot of sodium salt.
Soap: making soap is the oldest and most widespread use of caustic soda.
Sodium hydroxide has been used in traditional daily life. Today, soap, soap and other types of washing products still account for about 15 percent of the demand for caustic soda.
The main components of fats and vegetable oils are triglycerides (triglycerides), whose alkaline hydrolysis formula is:
(RCOO)3C3H5 (oil) +3NaOH=3(RCOONa) (sodium advanced fatty acid) +C3H8O3 (glycerol)
This reaction is the principle of soap production, hence the name saponification reaction.
R groups may be different, but the resulting r-coona can be used as soap. Common R- s are:
C17H33- : 8-17 c enyl. R-COOH is oleic acid.
C15H31- : n-15 alkyl. R-COOH is palmitic acid.
C17H35- : normal 17 - alkyl group. R-COOH is stearic acid.
Detergent: sodium hydroxide was used in the production of all kinds of detergent, and even now the washing powder (the composition such as sodium dodecyl benzene sulfonic acid) is created by a large amount of caustic soda, caustic soda is used in the sulfonation reaction after neutralizing excess fuming sulfuric acid.
Sodium hydroxide plays an important role in the papermaking industry. Because of its alkaline nature, it is used to cook and bleach paper.
The raw materials for paper making are wood or grass plants, which contain a considerable amount of non-cellulose (lignin, gum, etc.) in addition to cellulose. Adding dilute sodium hydroxide solution can dissolve the non-cellulosic components and separate them, so as to make the pulp with cellulose as the main component. 
Artificial fibers and textiles
Synthetic fibers such as spun rayon, wool, rayon, etc., are mostly viscose fiber, they are using cellulose, sodium hydroxide, carbon disulfide (CS2) as the raw material made of viscose, jet, made by condensation.
In the textile industry, sodium hydroxide is used for fiber treatment and dyeing, and for mercerizing cotton fiber. After the cotton fabric is treated with caustic soda solution, the wax, grease, starch and other substances covering the cotton fabric can be removed, and the silky color of the fabric can be increased to make the dyeing more even. 
Petroleum products also contain some acidic substances after sulphuric acid washing, which must be washed with sodium hydroxide solution and then washed before refined products can be obtained. 
The food industry
China's hygienic standard for the use of food additives (GB 2920-1996) stipulates that it can be used as processing AIDS and used appropriately according to production needs.
Sodium hydroxide can be widely used in the following production processes: cleaning of containers; Starch processing; Preparation of carboxymethyl cellulose; The manufacturing process of sodium glutamate. 
Sodium hydroxide is widely used in water treatment. In wastewater treatment plants, sodium hydroxide can reduce the hardness of water by neutralization reaction. In the industrial field, it is a regeneration agent of ion exchange resin. Sodium hydroxide has strong alkalinity and high solubility in water. Since sodium hydroxide is relatively soluble in water, it is easy to measure the amount of sodium hydroxide and can be used in various fields of water treatment.
Sodium hydroxide is used in water treatment of the following topics: elimination of water hardness; Adjust the pH of water; Neutralizing wastewater; Removal of heavy metal ions from water by precipitation; Regeneration of ion exchange resin.
Sodium hydroxide is used to treat bauxite, which contains alumina, the raw material for making aluminum. Alumina can be purified from concentrate by sodium hydroxide.
Reaction equation: Al2O3+2NaOH+H2O=2Na[Al(OH)4] or Al2O3+2NaOH=2NaAlO2+H2O 
Sodium hydroxide is also used to extract tungsten-refining raw materials from wolframite:
4 fewo4 + 8 naoh + 2 h2o + O2 = 4 na2wo4 + 4 fe (OH) 3
Sodium hydroxide is also used to make zinc alloys and zinc ingots.
