"On the Volatilization of Ethyl Acetate at Room Temperature"

Ethyl acetate is also an organic compound. It is lively and has a special aroma. It is often heard that the world is suspicious: Ethyl acetate can evaporate at room temperature?

According to the physical characteristics, the boiling point of ethyl acetate is about 77 ° C, which is higher than room temperature. However, it has a certain vapor pressure. At room temperature, although it does not reach the boiling point, the molecule still has enough energy to escape the liquid phase and cause volatilization.

When ethyl acetate is placed in an open container, at room temperature, it can be seen that its amount gradually decreases, because the surface molecules gain energy, break free from the attractive force between molecules, and escape into the gas phase. This volatilization rate is related to many factors. If the ambient temperature increases, the kinetic energy of the molecules increases, and the volatilization accelerates; the air circulation is good, taking away the volatile molecules, causing the concentration of ethyl acetate in the gas phase to be difficult to reach saturation, and also promoting volatilization.

And its volatilization is affected by the surface area of the container. If the surface area is large, more molecules have the opportunity to escape and evaporate faster. In addition, factors such as air humidity, although slightly affected, cannot be ignored. When the humidity is high, there are many water molecules in the gas phase, or there is an obstacle to the escape of ethyl acetate molecules.

In summary, ethyl acetate can indeed evaporate at room temperature. When we use it, we need to pay attention to its characteristics, keep it properly, prevent it from being lost, and avoid the safety of volatilization.
