Ethyl acetate is an ester that is synthesized from acetic acid and ethanol in the presence of strong acids like sulfuric acid in an esterification reaction. The two reactants and the H2SO4 catalyst are heated under reflux for approx. 40 min.
CH3CH2OH + CH3COOH → CH3COOCH2CH3 + H2O
Because the reaction is reversible and produces an equilibrium, yield is low unless driven to the right by removal of water. The yield can also be increased by using an acid chloride, acetyl chloride (CH3COCl), instead of the carboxylic acid. This is usually performed in the presence of a base such as pyridine (to remove HCl) and since it does not result in an equilibrium more of the ester is produced. It is unstable in the presence of strong bases like sodium hydroxide or strong acids like hydrochloric acid, and it is hydrolyzed back into ethanol and acetic acid, especially at elevated temperature.

Sneak-Peek of Global Oneness Community
Hi friend! The Global Oneness Community, the place for information and sharing about Oneness is not really launched yet (you will see there is still some clean up to do) ...but it is now open for a sneak-peek! And if you wish - please register and become one of the very first members to do so! Jonas
