The properties and uses of isopropanol play an important role in the field of raw materials for chemical production. As a common organic compound, isopropanol has many unique properties, so it has been widely used in various chemical processes. This article will discuss the properties and uses of isopropanol in detail.

1. properties of isopropyl alcohol

1. Physical properties
isopropyl alcohol is a colorless and transparent liquid with a special smell. It has a boiling point of 82.4°C, a melting point of -89.5°C and a density of 0.785g/cm³. Isopropanol is miscible with water and miscible with a variety of organic solvents.

2. chemical properties of
isopropanol with alcohol generality, can occur esterification, oxidation, dehydration and other reactions. In addition, isopropanol is also reductive and can be oxidized to acetone.

2. the use of isopropyl alcohol

1. solvent and cleaning agent
isopropyl alcohol has excellent solubility and cleaning ability, so it is widely used as a solvent and cleaning agent. In the chemical, pharmaceutical, electronic and other industries, isopropyl alcohol is often used to clean equipment, remove oil and so on.

2. Chemical raw materials
Isopropyl alcohol can be used as chemical raw materials for the production of various chemicals. For example, isopropyl alcohol can be oxidized to form acetone, and acetone can be further reacted to obtain methyl methacrylate.

3. Additive
isopropyl alcohol can be used as a gasoline additive, which can increase the octane number of gasoline, reduce engine carbon deposits, and improve combustion performance.

4. Antifreeze
The freezing point of isopropyl alcohol is low, so it can be used as an antifreeze to prevent equipment from freezing at low temperatures.

5. Disinfectant
isopropyl alcohol has a bactericidal effect and is widely used as a disinfectant and antiseptic, such as medical devices, surgical appliances, etc.

3. the production
of isopropanol There are two main methods for the production of
isopropanol: one is through the propylene hydration method, and the other is through the acetone reduction method. Among them, propylene hydration method is a commonly used method in industrial production, which uses propylene, water and catalyst as raw materials, and performs hydration reaction under certain temperature and pressure to generate isopropanol.
Precautions for storage and use of
4. isopropyl alcohol

1. Precautions for storage
isopropyl alcohol should be stored in a cool, ventilated and dry place, avoiding direct sunlight and high temperature. In addition, because isopropyl alcohol is flammable, it should be kept away from fire and heat sources.

2. use precautions
in the use of isopropyl alcohol, should pay attention to avoid contact with eyes and skin, if accidentally contact, should immediately rinse with water. In addition, since isopropyl alcohol is volatile, it should be used in a well-ventilated environment.

In conclusion, isopropanol, as a common organic compound, has a wide range of uses. In the field of chemical production raw materials, isopropanol has attracted much attention because of its unique properties and wide range of uses. During use, attention should be paid to storage and use safety to avoid harm to the human body and the environment.
