What Is the Boiling Point of Isopropyl Alcohol


What Is the Boiling Point of Isopropyl Alcohol?

Isopropyl alcohol, also known as rubbing alcohol, is a common household disinfectant and cleaner. It is a colorless and flammable liquid with a strong odor. One important characteristic of isopropyl alcohol is its boiling point, which affects its various applications. So, what exactly is the boiling point of isopropyl alcohol?

The boiling point of isopropyl alcohol is approximately 82.6°C (180.7°F) at atmospheric pressure. This means that at this temperature, isopropyl alcohol will start to vaporize and turn into a gas. However, it is important to note that the boiling point can vary slightly depending on the purity of the alcohol. Impurities can affect the boiling point, so it is essential to use high-quality isopropyl alcohol for accurate results.

Isopropyl alcohol’s relatively low boiling point makes it useful for a variety of purposes. It evaporates quickly, making it ideal for cleaning surfaces and disinfecting medical equipment. The rapid evaporation also means that it leaves behind minimal residue, making it a popular choice for cleaning electronics and delicate materials.
