WebSummary. This reaction is also known as the Fischer esterification. Esters are obtained by refluxing the parent carboxylic acid with the appropraite alcohol with an acid catalyst. The equilibrium can be driven to completion by using an excess of either the alcohol or the carboxylic acid, or by removing the water as it forms. WebEsters of carboxylic acid can be analysed analogously to the hydrocarbons according to standard Karl Fischer methods. Long-chain compounds require the addition of solubilisers, e.g. long-chain alcohols or chloroform. Unsaturated compounds can usually be …
