Hydrolysis of ethyl acetate and hydrochloric acid
Now there is ethyl acetate, hydrolyzed with hydrochloric acid as a catalyst.

The principle of hydrolysis, ethyl acetate meets hydrochloric acid, and water and ester phase combine. The structure of the ester is separated by this change. Ethyl acetate is produced by the condensation of acetic acid and ethanol. In contact with water and hydrochloric acid, its bond breaks.

In this case, the effect of hydrochloric acid is to promote the speed of the reaction. Although participating in the process, the reaction ended, and its quality and quantity were not changed. Between reactions, ethyl acetate gradually transformed into acetic acid and ethanol.

View the reaction formula: $CH_3COOC_2H_5 + H_2O\ stackrel {HCl} {\ rightleftharpoons} CH_3COOH + C_2H_5OH $. At first, the amount of ethyl acetate is large, and the amount decreases gradually with the reaction; while the amount of acetic acid and ethanol increases gradually. When it reaches equilibrium, the amount of various substances does not change.

In actual operation, temperature control, time control and the proportion of various substances are all important. If the temperature is high, the reaction will increase rapidly, but if it is too high, it may cause side reactions. Under moderate temperature, good results can be obtained. And the appropriate proportion of materials is also related to the whole reaction.

From this perspective, the hydrolysis of ethyl acetate and hydrochloric acid contains physical and chemical principles, which are useful in all things chemical.
