The synthesis of ammonium acetate
The ancient method of synthesizing ammonium acetate is based on the properties of the research substance, and it is clever to use the technique. From the beginning of its method, it is necessary to choose pure materials. Ammonium is often derived from ammonium salts, and its properties should be stable and pure; the preparation of acetic acid should also be clean and free of impurities, so that the base material can be obtained.

At the beginning of the production, ammonium salt and acetic acid should be placed in utensils according to an appropriate ratio. The degree of the ratio is related to the success or failure of the synthesis. More is surplus but useless, less is combined but insufficient, and the measurement must be carefully reviewed. Then, the temperature is moderate. If the temperature is high, the reaction is too fast, and it is easy to produce impurities; if the temperature is low, it should be slow, time-consuming and ineffective. Therefore, it is often dried slowly with a gentle fire, so that the materials in the vessel gradually melt.

In the meantime, it is necessary to stir frequently to make the materials uniform, and the speed and uniformity should be rapid. The stirring equipment, or bamboo and wood, or copper and iron, are all clean and free of staining the materials. When it should be finished, observe its color, smell its taste, and observe its shape. The color should be clear, and the taste should be compatible. If the shape is crystallized, it is good.

If you want to get a pure product, use the method of lustre to remove its impurities. The choice of lustre is fine and dense, so that the impurities cannot be exceeded, and the pure product can be stored. After lustre, place it in a ventilated and dry place, and wait for it to dry, and ammonium acetate is formed. It is also widely used, and has its effect in medicine and work, which is the result of ingenious craftsmanship.
