Ester interchange, between ethyl alcohol

Such interchanges include the molecular rearrangement of completely esteri-fied esters of glycerol and mixtures of fatty acids, such as vegetable and animal oils—e.g., cottonseed oil or tallow the ester-ester exchange between aromatic carboxylic acid esters of a monohydric alcohol, such as o-CeH (C02CH3)2, and aliphatic carboxylic acid esters of a polyhydric alcohol, such as triacetin or between monohydric alcohol esters of aliphatic carboxylic acids—e.g., ethyl stearate —and fatty acid esters of polyhydric alcohol—e.g., tributyrin or triolein.
