Fractionation of Ethyl Acetate and Butyl Acetate
Now there is a solution in which ethyl acetate and butyl acetate are mixed. If you want to separate them, you should use the method of fractionation.

The important thing about fractionation is the difference between the boiling points of the two. The boiling point of ethyl acetate is lower, and the boiling point of butyl acetate is slightly higher. During fractionation, put the mixed liquid in a still and heat it slowly.

At the beginning, the temperature gradually rises, reaching the boiling point of ethyl acetate, which is first vaporized into steam, which is then reformed into a liquid through a condenser and flows into a receiving vessel. At this time, the temperature is maintained near the boiling point of ethyl acetate, and when it is evaporated, the temperature gradually rises again.

When the temperature rises to the boiling point of butyl acetate, butyl acetate vaporizes into steam and is also collected by condensing into a liquid. Therefore, ethyl acetate and butyl acetate can be separated in sequence to obtain their pure products for different purposes. In the fractionation process, it is necessary to pay attention to the control of heat and temperature to obtain the best effect.
