Extraction of acetic acid from water with ethyl acetate

Nowadays, acetic acid is extracted from water with ethyl acetate. The extraction method takes advantage of the difference in solubility of the solute in different solvents to transfer the solute from one phase to another.

Water and ethyl acetate are incompatible with each other, and the solubility of acetic acid in the two is different. When ethyl acetate and water containing acetic acid are mixed and shaken, and left to stand for stratification, acetic acid is highly soluble in ethyl acetate, so it is transferred from the aqueous phase to the ethyl acetate phase to achieve the purpose of separation and extraction.

During operation, pay attention to the cleanliness and dryness of the instrument used, so that impurities such as waterproof separation can interfere with the extraction effect. The mixing oscillation process should be moderate to ensure that sufficient contact is conducive to the transfer of acetic acid, but not too violent emulsification phenomenon, which affects the stratification.

When standing for stratification, be patient and wait to make the two phases distinct. After stratification, carefully separate the upper and lower layers of liquid, collect the acetic acid-rich ethyl acetate phase, and then further treatment can be carried out according to demand, such as distillation and other means to obtain pure acetic acid, and recover ethyl acetate for recycling. In this way, the process of extracting acetic acid from water with ethyl acetate can achieve good results and achieve the goal of separation and purification.
