Usually the term ester means the ester of a carboxylic acid. In general, an acid and alcohol generate an ester and water . This is called a Fischer esterification.... The instant invention involves a process for preparing carboxylic acid esters which comprises coreacting a carboxylic acid and an aliphatic mono or polyol by maintaining one of the reactants in a reactor at elevated temperatures and adding the other reactant to the reactor over a period of time.

The standard method for preparing carboxylic acid hydrazides is hydrazinolysis of esters in alcoholic solutions. However, when applied to alpha,beta-unsaturated esters, the main product typically fenol acid and intestinal morphology pdf The benzilic acid rearrangement is formally the rearrangement reaction of 1,2-diketones into ?-hydroxy–carboxylic acids using base. This reaction receives its name from the reaction of benzil with potassium hydroxide to form benzilic acid.
