The melting and boiling point of ethyl acetate is the key to the change of its properties. The melting temperature of ethyl acetate is about -83.6 ° C. At this temperature, the solid-liquid phase is easy to solidify and gradually turn into a liquid. As for the boiling point, it is about 77.1 ° C. When it reaches this temperature, the liquid turns to gas, showing a boiling state, and the molecular thermal motion is dramatic, escaping the liquid phase. The characteristics of this melting and boiling point are of great significance in all things in the chemical industry, such as separation, purification, and control of reaction conditions. Making good use of its melting and boiling point can make the process better and the product better. It is an indispensable element in all kinds of chemical operations.
