The method of making ethyl acetate from ethanol
If you want to start with ethanol to make ethyl acetate, it is the key to chemistry. Ethanol is active and can be the essence of various reactions.

The method is often accompanied by a catalytic agent. Those with acids as catalysts, such as sulfuric acid, are added to the mixture of ethanol and acetic acid. The properties of sulfuric acid can promote the reaction of the two and increase the rate. The hydroxyl group of ethanol interacts with the carboxyl group of acetic acid to remove one molecule of water to form ethyl acetate. This reaction is reversible. In order to obtain more ethyl acetate, it is often necessary to adjust the various conditions of the reaction.

Controlling its temperature is very important. If the temperature is too high, the side reaction will start and the product will be impure; if the temperature is too low, the reaction will be slow and the yield will not be high. It is appropriate to adjust the temperature, between about hundreds of degrees Celsius, so that the reaction speed and the product are good.

Furthermore, the ratio of materials also needs to be considered. The amount of ethanol and acetic acid, when the stoichiometric ratio is slightly increased by a certain amount, can shift the balance to the right and obtain more products. If the amount of acetic acid is increased, the reaction can proceed more towards the formation of ethyl acetate.

When the reaction is carried out by a reflux device, the volatilization and fugitive dispersion of the reactant and the product can be reduced, and it can be kept in the system, so that the reaction is sufficient. And add stirring at times to make the material mix uniformly and the reaction

After the reaction is completed, the product is divided by distillation. The boiling point of ethyl acetate is different from that of ethanol and acetic acid. According to the difference in boiling point, pure ethyl acetate can be obtained. In this way, ethyl acetate can be obtained by various operations based on ethanol.
