Ethyl Ester Extraction
In ancient times, those who desire exquisite purification methods, among all kinds of techniques, quite heavy ethyl ester extraction techniques.

Ethyl ester extraction, the method uses ethyl ester as a medium and can be mixed into the mixture. Looking at the material, if there are various substances mixed, put it in a container and pour an appropriate amount of ethyl ester. Ethyl esters are mild in nature and are different from other substances.

At the beginning, stir it well to make the material fully contact with ethyl ester. The mixture is left to stand, like a still water, and then it changes quietly. Due to the different densities of ethyl ester and other substances, the solubility is also different, and the substances are gradually divided. The desired essence is mostly soluble in ethyl ester, like a pearl in the arms, which is different from impurities.

Then use a liquid separator to carefully separate. Take the upper or lower liquid (depending on the density of ethyl ester and the dissolved essence), and then distill and other methods to remove ethyl ester and leave the essence. In this way, pure things can be obtained, which can be used in medicine, chemistry and other industries. The effect is remarkable, and it is a good way to purify.
