Salts and esters of propionic acid and anions CH3CH2CO2− are known as propionates or propanoates. It is a colourless oily liquid with a rancid smell that produces irritating vapour. Propionic acid is a short-chain saturated fatty acid that consists of ethane attached to the carbon of a carboxy group. Let us know the chemical properties of propionic acid.
