The acidic formation of ethyl acetate is an exothermic process with an estimated 16–40 kJ. mol-1 activation energy. The enthalpy of ethyl acetate formation in the liquid form is approximately -480 kJ.
What happened when ethyl acetate is hydrolysed in presence of acid?
When ethyl ethanoate is heated under reflux with a dilute acid such as dilute hydrochloric acid or dilute sulfuric acid, the ester reacts with the water present to produce ethanoic acid and ethanol.22 jan. 2023
What is the product of the hydrolysis of ethyl acetate?
Ethyl acetate is rapidly hydrolyzed to ethanol and acetic acid.
