The nature and use
of sodium hydroxide
sodium hydroxide, also known as caustic soda or caustic soda, is an inorganic compound with wide application in the field of chemical production raw materials. Its molecular formula is NaOH, consisting of one sodium ion and one hydroxide ion. Sodium hydroxide has a variety of unique properties that make it play an important role in many chemical processes.

1. the nature of sodium hydroxide

1. physical properties: sodium hydroxide is a white solid, has a strong hygroscopicity, can quickly absorb moisture in the air. Its solubility is very good, soluble in water, ethanol and glycerol, but insoluble in acetone.
2. chemical properties: sodium hydroxide is a strong alkali, has a strong corrosive. It can neutralize with the acid to form the corresponding salt and water. In addition, sodium hydroxide can also react with many non-metallic oxides to form the corresponding acid salts and water.

2. the use of sodium hydroxide

in the field of chemical production raw materials, sodium hydroxide has a wide range of uses, the following is its main application areas:

1. Paper industry: sodium hydroxide in the paper industry is mainly used as a cooking agent, used to remove lignin and hemicellulose in wood, so that cellulose is separated and made into pulp. In addition, sodium hydroxide can also be used to adjust the pH value of the pulp and improve the quality of the pulp.
2. Textile industry: In the textile industry, sodium hydroxide is commonly used in mercerizing and scouring processes. The mercerizing process is to treat the cotton fiber with sodium hydroxide to increase its luster and strength. The scouring process uses sodium hydroxide to remove impurities and natural pigments from the textile.
3. Soap and detergent production: Sodium hydroxide is an important raw material for the production of soaps and detergents. It reacts with grease to produce saponification, which can be further processed into soaps and detergents.
4. Petroleum industry: In the petroleum industry, sodium hydroxide is commonly used in acidification treatment and purification processes. It can react with the acidic substances in the oil to produce salt and water, thereby improving the quality of the oil.
5. Food industry: In the food industry, sodium hydroxide is mainly used to adjust the pH value of food and as an auxiliary agent in food processing. For example, when making pasta and pastries, an appropriate amount of sodium hydroxide can be added to increase the elasticity and color of the pasta.

In general, sodium hydroxide has a wide range of applications in the field of chemical production raw materials, mainly due to its unique physical and chemical properties. However, in the process of using sodium hydroxide, special attention should be paid to its corrosion and safety issues, and operation under suitable conditions should be ensured to ensure the safety and efficiency of production.
