Phosphate esters are biologically important (nucleic acids belong to this group) and are used widely in industry as solvents, plasticizers, flame retardants, gasoline and oil additives, and insecticides. Ethanoic acid + ethanol ⇆ ethyl ethanoate + water with sulphuric acid as a catalyst CH 3 COOH + C 2 H 5 OH ⇆ CH 3 COOC 2 H 5 + H 2 O • Describe the structure of the ester, ethyl ethanoate. Here dilute acid is used as an acid catalyst. Esters that are have fragrant odours are used as a constituent of perfumes, essential oils, food flavourings, cosmetics, etc. They are used to manufacture synthetic fibers such as polyester and plastics. Note: These reactions are exactly the reverse of those used to make an ester from a carboxylic acid and an alcohol.The only difference in that case is that you use a concentrated acid as the catalyst.
