Ethanol to ethyl acetate
Now I want to use ethanol as a material to make ethyl acetate. Ethanol, an organic alcohol, is also active and can react with other substances in various ways.

To obtain ethyl acetate, ethanol needs to be oxidized to form acetic acid first. Often supplemented by a catalyst, ethanol can react with oxygen at a suitable temperature and pressure. The reason for the reaction is that the carbon of the hydroxyl group in ethanol loses hydrogen to obtain oxygen, gradually converts to a carboxyl group, and then forms acetic acid.

Acetic acid is obtained, and then esterified with ethanol. This reaction requires acid as a catalyst, often concentrated sulfuric acid. Under heating conditions, the carboxyl group of acetic acid interacts with the hydroxyl group of ethanol to remove a molecule of water and form ethyl acetate. In the process, concentrated sulfuric acid is not only a catalyst, which increases the rate of reaction, but also has the property of water absorption, so that the equilibrium of the reaction shifts to the right, increasing the yield of ethyl acetate.

The process of preparing ethyl acetate, the control of conditions is of paramount importance. If the temperature is too high, the reactants or volatilization will also increase the side reactions; if the temperature is too low, the reaction rate will be slow and the yield will not be high. And the ratio of raw materials and the amount of catalyst are all related to the effect of the reaction. After fine operation and careful regulation, high-purity ethyl acetate can be obtained to meet the needs of chemical, fragrance and other industries.
