Ethanol synthesis of ethyl acetate
If you want to make ethyl acetate, using ethanol as the base is actually the main way of chemistry. Ethanol, an ordinary alcohol, has mild properties and is a good material for synthesis.
The method also requires a catalyst to help the reaction proceed. Sulfuric acid is a commonly used catalyst, which can promote the interaction between ethanol molecules and make chemical bonds easy to break. In this process, the hydroxyl group of ethanol is separated from the hydrogen atom of other ethanol molecules, combined with the oxygen atom, and gradually converted into the structure of ethyl acetate.
When reacting, temperature is also critical. If the temperature is too high, or cause side reactions, the product is not pure; if the temperature is too low, the reaction is slow, time-consuming and laborious.
And this reaction is reversible. To obtain a high yield of ethyl acetate, it is necessary to control the reaction conditions. Or increase the amount of reactants, in order to balance the principle of movement, so that the reaction tends to produce products; or remove the product in time, but also promote the reaction forward.
At the end of the preparation, the product needs to be purified. By distillation, ethyl acetate can be divided into unreacted ethanol and by-products according to the difference in boiling point to obtain pure ethyl acetate. From this point of view, the synthesis of ethyl acetate from ethanol requires fine operation and good control conditions, but it can provide important raw materials for many fields of chemical industry, and its value is not light.
