In addition to ethyl acetate in the compound
The method of removing ethyl acetate from the compound
There are three methods.

First, the method of distillation. The boiling point of ethyl acetate is 77.1 ° C, which is lower than that of most compounds. If the boiling point of the compound is suspended from it, distillation can be performed. The compound containing ethyl acetate is placed in a distiller and slowly heated to near the boiling point of ethyl acetate. The ethyl acetate is first vaporized and liquefied through a condenser tube. When collected, the compound remains in the container. This can be divided into two.

Second, the method of extraction. Find a solvent that is miscible with ethyl acetate and insoluble or unreactive with the compound. Place the mixture in a separation funnel with the solvent and shake it to dissolve the ethyl acetate into the solvent. After static layering, the solvent and compound containing ethyl acetate can be obtained by liquid separation, and then the solvent and ethyl acetate can be separated by distillation or other methods.

Third, the method of adsorption. Choose activated carbon, silica gel and other adsorbents, and the mixture is co-placed with the adsorbent. The adsorbent has adsorption properties for ethyl acetate, and ethyl acetate can be left to make the compound purer. After filtering and other methods to remove the adsorbent, the compound of ethyl acetate can be obtained.

All these methods have their own suitability. When selected according to the nature, amount and actual situation of the compound, the purpose of removing ethyl acetate is achieved, so that the compound is pure.
