Esterification is when an alcohol and a carboxylic acid react together in order to create an ester. It can also be created when either acyl chlorides and alcohols react, or when acid anhydrides and alcohols react[1].
The ester is named by counting the carbons on the alkyl chain as the first part of the name, followed by counting the carbons on the carboxyl chain for the second part of the name[2].
For example: CH3COOCH2CH2CH2 is named propyl ethanoate. As this is comprised from propanol and ethanoic acid.
Esterification can also happen in a reaction between phosphoric acid and an alcohol, this forms phosphate esters[3]. A second alcohol can then react with the phosphate ester which forms a phosphodiester[4].
