Industrially, ethanol is produced by reacting ethene with steam. This reaction is carried out at 300 ^{\circ}C and 60 atmospheres. C$_2$H$_4$(g) + H$_2$O(g) ⇌ C$_2$H$_5$OH(g) A catalyst is employed in this reaction. The forward reaction gives out heat.

A carboxylic acid and an alcohol combine to make an ester and water. Under some conditions, the process can be carried out in reverse, so an ester reacts with water to give a carboxylic acid X and an alcohol Y. An equilibrium is established. $\text{CH}_3\text{CH}_2\text{COOCH}_3 + \text{H}_2\text{O} \rightleftharpoons X + Y$ The forward reaction absorbs heat.
