Study of Organic Solvent Hydrophobicity on Lipase Catalyzed Reaction Esterification

The paper studies the effect of hydrophobicity of nonpolar organic solvents (cyclohexane, n-hexane and isooctane) on lipase-catalyzed esterification of glycerol with oleic acid catalysed by immobilized 1, 3-specific Mucor miehei lipase. The esterification was carried out with and without molecular sieves in a batch stirred-tank reactor (BSTR). Enzyme selectivity was in function of solvent hydrophobicity and related to the system with molecular sieves, where the equilibrium was shifted toward the production of diolein.
