ESTERIFICATION PROCESS

The present disclosure relates to a process of esterification in presence of a catalyst. The catalyst of the present disclosure is an aryloxy based phosphoric acid having general formula [{ArO}2P(O)OH] and is represented by the structure: wherein, Ar represents aryl compounds. The process of esterification is carried out by the reaction of a carboxylic acid and an alcohol in a fluid medium in the presence of the aryloxy based phosphoric acid catalyst resulting in the corresponding ester. The process of the present disclosure is simple and results in a product having a comparatively higher purity.

Electrogenerated N-heterocyclic carbene in ionic liquid: An insight into the mechanism of the oxidative esterification of aromatic aldehydes

An N-heterocyclic carbene (NHC), generated by cathodic reduction of BMIm BF4, mediates the oxidative esterification of aromatic aldehydes with organic bromides in the corresponding ionic liquid as solvent. The product recovery by simple extractive work-up with diethyl ether allowed the ionic liquid to be recycled up to 9 times for subsequent electrolyses, with no significant loss in the product yield. The isolation of an intermediate, whose structure was confirmed by synthesis and transformation into the ester, provided the key for a mechanistic insight into the reaction.
