The method of ethanol precipitation of ammonium acetate
The method of ethanol precipitation of ammonium acetate is quite important. The method uses ethanol as the medium and ammonium acetate as the quality, and the two are combined to achieve the purpose of purification.

Prepare a clean vessel first, hold an appropriate amount of ammonium acetate solution, and slowly drop into ethanol. When ethanol encounters ammonium acetate, its molecules interact, and the solubility of ammonium acetate gradually decreases, so it appears to precipitate. At this time, the solution gradually becomes turbid, and the particles gradually accumulate. It is like the beginning of a cloud, and then it settles, like dust and sand falling to the ground.

Compound it with a filter to obtain precipitation. However, the precipitation or impurities need to be washed with ethanol many times. In the process of purification, ethanol is like a messenger, carrying impurities away, leaving a pure ammonium acetate precipitate.

When the precipitate is drained, the ethanol evaporates and finally obtains pure ammonium acetate. This method of ethanol precipitation of ammonium acetate is of great benefit to the purification of the product.
