Post  bejoy on Wed Jan 03, 2018 12:22 am

Esters are compounds that belong to the organic functional group which has and also forms sweet smelling compounds. The formula for ester is generally denoted by RCOOR’, where R and R’ are alkyl groups or an aryl groups that are produced by the reaction of an alcohol and an acid. When it is heated along wth a hydroxide some esters decay to generate soap and glycerin it is known as saponification. Certain fats and oils are mixtures of distinct esters, such as stearin, palmitin and linolein, produced from the alcohol,glycerol and fatty acids. Natural ester occurs in organic acids in fruits and flowers that give a distinguishing odor.

Preparation of esters

The common method of preparing esters is by Fischer Etherification. This process involves mixing a carboxylic acid and with alcohol in the occurrence of dehydrating agent.

The reaction is as follows
RCO2H + R’OH = RCO2R’ + H2O
