Barium hydroxide is an inorganic compound with strong alkaline and corrosive properties. In the field of chemical production raw materials, barium hydroxide is widely used in various chemical reactions and processing processes. This article will detail the properties and uses of barium hydroxide.

1. the nature of barium hydroxide

1. physical properties
barium hydroxide is a white crystalline powder, with strong hygroscopicity. It is easily soluble in water and gives off a lot of heat when dissolved. The melting point of barium hydroxide is low, about 78 ℃, and the boiling point is high, reaching 780 ℃.

2. chemical properties of
barium hydroxide is a strong base, has a strong corrosive. It can neutralize with the acid to form the corresponding salt and water. In addition, barium hydroxide can also react with some non-metal oxides, salts, etc.

2. the use of barium hydroxide

1. Chemical production
In chemical production, barium hydroxide is used as a catalyst, desiccant and absorbent for many chemical reactions. It can be used to manufacture various chemicals, such as fertilizer, plastic, rubber, paint, etc.

2. Petroleum industry
In the petroleum industry, barium hydroxide is used to increase the pH of crude oil to promote the emulsification and demulsification of crude oil. In addition, it can also be used to remove metal ions and acid gases from oilfield wastewater.

3.
of the pharmaceutical industry Barium hydroxide in the pharmaceutical industry can be used as raw materials for the treatment of gastric acid, ulcers and other diseases. In addition, it can also be used to prepare some external medicines and disinfectants.

4. Food industry
In the food industry, barium hydroxide is used as a food additive, which can be used to adjust the pH of food and improve the taste of food. However, it should be noted that barium hydroxide has certain toxicity, and its dosage and use conditions must be strictly controlled.

In short, barium hydroxide has a wide range of uses in the field of chemical production raw materials, but because of its strong alkaline and corrosive, special attention should be paid to safety measures and operating procedures.
