isopropyl alcohol boiling point and melting point respectively?

Isopropyl alcohol (chemical formula: C- H-O), also known as 2-propanol, is a common organic chemical substance, widely used in chemical industry, medicine, electronics, disinfection and other fields. Understanding the physical properties of isopropyl alcohol is very important for its correct use in practical applications. In particular, the boiling point and melting point, two key physical parameters, not only affect its storage and transportation, but also determine its stability and reactivity in different environments. What is the boiling point and melting point of isopropanol?

Isopropyl alcohol boiling point

The boiling point of isopropanol is 82.6°C. The boiling point is the temperature at which a substance changes from a liquid to a gaseous state. Under standard atmospheric pressure, isopropanol will boil at 82.6°C. This boiling point is very important for many chemical processes, especially in distillation, solvent use, etc. For isopropyl alcohol, its boiling point is lower than that of water (100°C), which means that it can volatilize quickly at a lower temperature, so it is necessary to pay attention to temperature control during use to avoid excessive volatilization.

The boiling point is usually related to the interaction force between molecules. Isopropanol molecules contain a hydroxyl (-OH) group, which allows the formation of hydrogen bonds between molecules, and the boiling point of isopropanol is relatively high compared to other molecules without hydrogen bonds. Its boiling point is closely related to its molecular structure and polarity.

Isopropyl alcohol melting point

The melting point of isopropanol is -89.5°C. The melting point is the temperature at which a substance changes from a solid to a liquid. Isopropanol has a lower melting point due to the presence of weaker van der Waals forces and hydrogen bonds between its molecules. When the temperature drops to -89.5°C, isopropanol changes from liquid to solid.

The characteristics of low melting point make isopropyl alcohol in low temperature environment will not easily freeze, suitable for use in cold areas. For example, in some coolant, disinfectant and other products, the low melting point of isopropyl alcohol as a solvent or auxiliary helps it to maintain a liquid state at low temperature and ensure the stability of its function.

The Boiling Point and Melting Point of Isopropanol for Application

What is the boiling and melting point of isopropyl alcohol? This is important for many application scenarios. In the chemical industry and in the laboratory, understanding these physical properties of isopropyl alcohol can help optimize the conditions of use. Its low melting point and boiling point make it widely used in solvents, detergents and chemical synthesis. Especially in the process of gas absorption, dissolution, extraction, etc., isopropanol can maintain a liquid state at a lower temperature and play a good dissolution effect.

Isopropyl alcohol is highly volatile, so it is necessary to pay attention to fire prevention and safety issues when using it. Especially in high temperature environments, isopropyl alcohol may quickly evaporate and form flammable gases, thereby increasing the risk of fire. Therefore, knowing its boiling point and melting point helps to control safety in use.

Conclusion

Through the analysis of this article, we know that the boiling point and melting point of isopropyl alcohol are respectively, and the answer to this question is 82.6°C and -89.5°C respectively. Understanding the physical properties of isopropyl alcohol not only helps to optimize its use in industry, but also ensures its safety in different environments. In daily life, we can also choose suitable isopropyl alcohol products according to these characteristics to maximize its effectiveness.
