title: Production of glycerides from glycerol and fatty acid by immobilized lipases in non-aqueous media.
abstract: Immobilized Mucor miehei lipase catalyzes synthesis reactions between glycerol and oleic acid. No organic solvent is necessary to solubilize the substrates, which allows for the use of a reaction medium solely composed of the necessary substrates. Water produced in the reaction evaporates due to the high temperature used for the process. A conversion of 86% of oleic acid into triolein is obtained when using the substrates in stoichiometric amounts. Varying the ratio of glycerol over oleic acid allows for the preferential synthesis of one of the glycerides. Some batch reactors have been set up using different means of removing the water: spontaneous evaporation, molecular sieves, vacuum, and dry air bubbling.
