Potassium hydroxide (Potassium Hydroxide, referred to as KOH) is an important inorganic chemical raw materials, widely used in the field of chemical production. In this paper, the nature and use of potassium hydroxide are introduced in detail.

1. the nature of potassium hydroxide

potassium hydroxide is a white solid, with strong alkaline and corrosive. It is easily soluble in water and gives off a lot of heat when dissolved. The aqueous solution of potassium hydroxide has a greasy feeling, because it has a strong alkaline, can make oil and other organic decomposition.

potassium hydroxide is highly corrosive and has a corrosive effect on metals, glass, ceramics and other substances. Therefore, when storing and using potassium hydroxide, it is necessary to select suitable containers and equipment to avoid losses caused by corrosion.

2. the use of potassium hydroxide

1. chemical production

potassium hydroxide in chemical production has a wide range of applications, mainly used in the manufacture of various potassium salt, potassium fertilizer, potassium glass and so on. In addition, potassium hydroxide can also be used as a raw material for electrolytic production of metal potassium.

2. Food industry

Potassium hydroxide is often used as a food additive in the food industry, mainly to adjust the pH. For example, potassium hydroxide needs to be used to adjust the pH of the dough when making pasta, biscuits and other foods to improve the taste and quality of the food.

3. pharmaceutical manufacturing

potassium hydroxide in pharmaceutical manufacturing also has an important application, commonly used as raw materials and preparations of auxiliary raw materials. For example, in the production process of some drugs, it is necessary to use potassium hydroxide to adjust the pH value of the drug solution to ensure the stability and effectiveness of the drug.

4. detergent

potassium hydroxide has a strong cleaning ability, is often used to make a variety of cleaning agents. For example, some detergents, detergents and other cleaning products contain potassium hydroxide components, which can remove grease, stains and other dirt.

In short, potassium hydroxide, as an important inorganic chemical raw material, has a wide range of applications in the field of chemical production raw materials. Because of its strong alkalinity and corrosiveness, special attention should be paid to safety when using it to avoid harm to human body and environment.
