Ethyl acetate is a common organic solvent with low polarity and high solubility, so it is often used as an extractant in chemical experiments. Ethyl acetate extraction is a commonly used separation method, mainly used to separate the target product from the mixture.

The principle of ethyl acetate extraction is mainly to use the difference in solubility of the target product in ethyl acetate to extract the target product from the mixture. The specific extraction steps are as follows:

  1. Mix the mixture to be separated with ethyl acetate and stir evenly.
  2. Let the mixture stand for a while and let it separate into layers. At this time, the target product will dissolve from the mixture into ethyl acetate.
  3. Separate the lower layer mixture and the upper layer ethyl acetate. Usually, pouring or centrifugal separation can be used.
  4. Evaporate or distill the upper layer ethyl acetate to obtain the purified target product.

Ethyl acetate has certain toxicity, so safety should be paid attention to during operation. In addition, specific extraction conditions (such as temperature, pressure, time, etc.) need to be adjusted according to actual conditions. At the same time, for some special mixtures, other extractants or auxiliary methods may be needed to achieve better separation effects.

Extraction and separation equipment is indispensable in the implementation of ethyl acetate extraction and separation process. Extraction and separation equipment mainly includes centrifugal extractors, mixer settlers, extraction towers, etc. Zhengzhou Tiei Extraction is a supplier of liquid-liquid extraction and separation equipment. It independently innovates and develops CWL-M high-efficiency new centrifugal extraction technology, which not only has high extraction and separation efficiency, good separation effect, less entrainment, but also has low power, which is only one-third of the power of traditional centrifugal extractors. The equipment adopts a fully enclosed design and continuous operation. It is currently an extraction and separation equipment with good extraction effect in domestic and foreign applications.
