Does Ethylene Glycol Evaporate at Room Temperature?
Ethylene glycol is a clear, colorless, and odorless liquid that’s commonly used as an antifreeze in a variety of applications, such as automobiles, HVAC systems, and industrial processes. Despite it’s widespread use, there’s some confusion among people about whether or not ethylene glycol evaporates at room temperature.
In fact, the vapor pressure of pure ethylene glycol at room temperature is so low that it’s often considered negligible in practical terms.
The vapor pressure of a substance is a measure of the tendency of it’s molecules to evaporate from the surface into the surrounding atmosphere. The higher the vapor pressure, the more readily a substance will evaporate, and the more of it will be present in the atmosphere.
There are several factors that can affect the rate of evaporation of ethylene glycol. These include the temperature and humidity of the surrounding environment, the surface area of the liquid, and the presence of any impurities or contaminants. Higher temperatures and lower humidity levels can increase the rate of evaporation, whereas the presence of contaminants can decrease it.
This can occur, for example, when the liquid is heated or exposed to a high-pressure environment. In some cases, these vapors can be irritating or harmful to human health, especially if they’re breathed in over a prolonged period of time.
