Esterification of oleic acid with ethanol catalysed by 12-tungstophosphoric acid supported on alumina

Ester of organic acids and alcohols form an industrially important class of substances.They are mainly produced as components of esterification reactions.Esterification as well as transesterification reactions has been largely applied to the production of biodiesel,which may be defined as alkyl este...
