The esterification reaction of ethyl acetate

The esterification reaction of ethyl acetate with fudemine should be investigated in detail. Acetic acid and ethanol, catalyzed by concentrated sulfuric acid and heated, can produce this reaction.

The reaction formula is: $CH_ {3} COOH + C_ {2} H_ {5} OH\ underset {\ Delta} {\ overset {concentrated sulfuric acid} {\ rightleftharpoons}} CH_ {3} COOC_ {2} H_ {5} + H_ {2} O $. Among them, concentrated sulfuric acid is the catalyst, which can promote the reaction rate and has the property of water absorption, which can shift the equilibrium to the right and increase the yield of ethyl acetate. The purpose of heating is to increase the energy of molecules to speed up the reaction rate, and to make the resulting ethyl acetate evaporate, which is conducive to the positive balance movement.

When reacting, pay attention to the order of operation. Add ethanol first, then slowly add concentrated sulfuric acid, and oscillate while adding to prevent local overheating. After cooling, add acetic acid. In the device, use a saturated sodium carbonate solution to collect ethyl acetate. This is because the sodium carbonate solution can absorb unreacted acetic acid, dissolve ethanol, and reduce the solubility of ethyl acetate, which is convenient for stratification and separation to collect pure ethyl acetate.

Looking at this reaction, it is a typical esterification reaction in organic chemistry. It is of great value in industrial production and daily applications, and can be used for the preparation of fragrances, solvents, etc., which is of far-reaching significance in the field of chemistry.
