The formation of ethyl acetate
The formation of ethyl acetate of Fuzimine should be investigated. Its formation is often based on acetic acid and ethanol, with sulfuric acid as a catalyst, and co-heating.

Acetic acid, with carboxyl group; ethanol, containing hydroxyl group. When heated, under the catalysis of sulfuric acid, the carboxyl group and hydroxyl group combine to remove a molecule of water to form ethyl acetate. The reaction formula is as follows:
$CH_ {3} COOH + C_ {2} H_ {5} OH\ underset {\ Delta} {\ overset {H_ {2} SO_ {4}} {\ rightleftharpoons}} CH_ {3} COOC_ {2} H_ {5} + H_ {2} O $

This reaction is reversible. To increase the yield of ethyl acetate, you can add the amount of one reactant, or go to the water produced by the reaction. Sulfuric acid is used as a catalyst to increase the reaction speed, but it is strong, so use it carefully.

Also, the temperature of the reaction is also important. If the temperature is suitable, the reaction speed and yield are good; if the temperature is high, the side reaction will cause damage to ethyl acetate; if the temperature is low, the reaction will be delayed and the yield will be low.

When preparing, the device is also heavy. A reflux device is commonly used to return the untreated reactants and increase the rate of raw materials. After the reaction is completed, pure ethyl acetate can be obtained by the method of separation and distillation.

In short, the formation of ethyl acetate depends on the selection of substances, the help of catalysts, the control of temperature and the goodness of the method.
