In chemistry, an ester is a chemical compound derived from an acid (organic or inorganic) in which at least one âOH (hydroxyl) group is replaced by an âOâalkyl (alkoxy) group.[1] Usually, esters are derived from a carboxylic acid and an alcohol.
The equilibrium constant for such reactions is about 5 for typical esters, e.g., ethyl acetate. The reaction is slow in the absence of a catalyst. Sulfuric acid is a typical catalyst for this reaction. Many other acids are also used such as polymeric sulfonic acids.sters are widespread in nature and are widely used in industry. In nature, fats are, in general, triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries.
