Ester is the condensation product of an Carboxylic acid and alcohol in organic chemistry.In condensation two molecules combine such that the eleimination of small molecule like water takes place. Or it could be said that ester are dehydration product of alcohol and carboxylic acid. Reaction could be written as : RCOOH (Carboxylic acid) + HO-R' (alcohol) â RCOOR' (Ester ) Esters can be identified by the presence of -COO- linkage in the organic compound.
Esterification. Esterification is a chemical reaction used for making esters. The reaction in which a Caboxylic acid combines with an alcohol in the presence of a catalyst (commonly concentrated sulfuric acid) to form an ester [CH 3 COOC 2 H 5 ] is called Esterificatin reaction. It is a reversible reaction. The esters so formed are fruity in odor. They are sweet smelling compound. For example, acetic acid esterification in excess Ethanol in the presence of concentrated H 2 SO 4 as a catalyst results in an ester (ethyl actate) as well as carboxylic acids, with the removal of water molecule. Due to this, esterification reaction is also called ' Dehydration reaction '.
