What is Esterification?
The chemical reaction between a carboxylic acid and an alcohol to form an ester and water. It is a reversible, acid-catalyzed reaction (Fischer esterification). The equilibrium is shifted toward ester formation by removing water or using excess of one reactant.

The chemical reaction between a carboxylic acid and an alcohol to form an ester and water. It is a reversible, acid-catalyzed reaction (Fischer esterification). The equilibrium is shifted toward ester formation by removing water or using excess of one reactant.
Esterification produces: flavour esters (isoamyl acetate = banana, ethyl butanoate = pineapple), plasticisers (phthalate esters), solvents (ethyl acetate), polymers (polyesters: PET, Dacron), biodiesel (transesterification of triglycerides), and pharmaceutical esters (aspirin, cocaine).
Concentrated H₂SO₄ catalyst is corrosive and a dehydrating agent. Many carboxylic acids and acid chloride/anhydride alternatives are irritants or corrosive. Volatile esters are flammable. Reflux setups require proper clamps, cooling, and ignition source exclusion.
The formula or notation for Esterification is: ROH + RCOOH ⇌ RCOOR' + H₂O (H⁺ catalyst)
