Laboratory report on esterification abstract: this report presents the process of producing an ester, specifically isopentyl acetate esters are derivatives of carboxylic acids in which the acyl carbon bears an alkoxy substituent (-or) instead of the hydroxyl substituent (-oh) of the acid esters tend to have pleasant, fruity odors. Esterification is a straightforward reaction that utilizes several key techniques in synthetic organic chemistry one direct approach, known as the fischer esterification reaction, involves the acid-catalyzed condensation of an alcohol and a carboxylic acid, yielding an ester and water.
This was first demonstrated in 1862 by berthelot and saint-gilles (32), who found that when equivalent quantities of ethyl alcohol and acetic acid were allowed to react, the esterification stopped when two-thirds of the acid had reacted. Since we only had a 75 minute period to complete this lab, we needed to speed up the process of esterification – therefore, we used sulfuric acid to do so conclusion: as already covered, esterification is a chemical reaction used for making esters. Lab report 10 – esterification: preparation of methyl benzoate the purpose of this lab was to generate an ester through acid-catalyzed esterification of a carboxylic acid with an alcohol, a process known as fisher esterification an ester is a derivative of a carboxylic acid.
