What is the Boiling Point of Methyl Alcohol?

The boiling point of methyl alcohol is approximately 64.7°C (148.5°F) at standard atmospheric pressure. This relatively low boiling point makes methyl alcohol highly volatile, meaning it can easily evaporate at room temperature. This property is crucial in various applications, from industrial processes to laboratory settings.

Factors Affecting the Boiling Point of Methyl Alcohol

Several factors can influence the boiling point of methyl alcohol. Understanding these factors is essential for handling and using methyl alcohol safely and effectively.

Pressure: The boiling point of methyl alcohol decreases with a decrease in atmospheric pressure. At higher altitudes, where the atmospheric pressure is lower, methyl alcohol will boil at a lower temperature.
Impurities: The presence of impurities can alter the boiling point. Pure methyl alcohol has a specific boiling point, but impurities can cause it to boil at a different temperature.
Temperature: The ambient temperature can affect the rate of evaporation, which in turn influences the boiling point. In colder environments, methyl alcohol may evaporate more slowly.

Applications of Methyl Alcohol

Methyl alcohol's unique properties, including its boiling point, make it suitable for a wide range of applications. Some of the most common uses include:
