Bachine, also known as sodium hydroxide or caustic soda, is an inorganic compound with strong alkalinity. In the field of raw materials for chemical production, pertine has a wide range of uses, mainly due to its unique chemical properties. This article will discuss in detail the nature and use of pertine.

1. the nature of

1. physical properties: pearl alkali is usually a white solid, has a strong hygroscopicity, can quickly absorb moisture in the air. It has a high melting point of about 318 ℃ and a boiling point of 1390 ℃. Pertine is readily soluble in water and releases a large amount of heat when dissolved.
2. chemical properties: pearl alkali is a strong alkali, has a strong corrosive. It can neutralize with the acid to form the corresponding salt and water. In addition, the pearl alkali can also react with many non-metal oxides, salts and other compounds.

2. the use of

1. chemical production: pearl alkali in chemical production has a wide range of uses, can be used as raw materials to produce a variety of chemical products. For example, it can be used in the production of pulp, soap, detergents, dyes, plastics, etc.
2. Food processing: pearl alkali in food processing can be used as acidity regulator and preservative. It can adjust the pH of food and extend the shelf life of food.
3. pharmaceutical manufacturing: pearl alkali in pharmaceutical manufacturing can be used as raw materials for the production of various drugs, such as antibiotics, vitamins and so on.
4. Water treatment: pearl alkali has a good effect in water treatment. It can neutralize acidic substances in water, adjust the pH of water, and achieve the purpose of purifying water quality.

In short, the pearl alkali in the field of chemical production raw materials has a wide range of uses, to promote the development of the chemical industry is of great significance. In the process of using pearl alkali, it is necessary to pay attention to its strong alkalinity and corrosiveness, and take necessary protective measures to ensure production safety.
