Esters are formed by the condensation reaction between an alcohol and a carboxylic acid. This is known as esterification. In a condensation reaction, two Master Organic Chemistry Reaction Guide. Conversion of carboxylic acids to esters using acid and alcohols (Fischer Esterification). Description: 1-reaction of carboxylic acid with alcohol to make ester fischer esterification.gif.

Esters are produced when carboxylic acids are heated with alcohols in the presence of an acid catalyst. The catalyst is usually concentrated sulphuric acid. Dry hydrogen chloride gas is used in some cases, but these tend to involve aromatic esters (ones containing a benzene ring). SQA Chemistry.

Okay, get ready for a little organic chemistry. I know, I can hear some of you saying, “But it’s summer.

Dry hydrogen chloride gas is used in some cases, but these tend to involve aromatic esters (ones where the carboxylic acid contains a benzene ring). SQA Chemistry. 2. Nature's chemistry (d) Esters, fats and oils. An ester is a molecule containing an ester link: ─COO─. Esters are used as flavourings and fragrances as many have pleasant, fruity smells. Esters are also used as solvents for non-polar compounds that do not dissolve in water.
