N-Butyl oleate

Lipases (E.C. 3.1.1.3.) catalyze the hydrolysis of lipids at an oil/water interface. In a membrane reactor, the enzymes were immobilized both on the side of the water phase of a hydrophobic membrane as well as on the side of the organic phase of a hydrophilic membrane. In both cases, no other means for stabilization of the emulsion at the membrane were required. The synthesis reaction to n-butyl oleate was achieved with lipase from Mucor miehei, which had been immobilized at the wall of a hollow fiber module. The degree of conversion reached 88%, but the substrate butanol decomposed the membrane before the enzyme was deactivated.

In 1995, Kwon, Song, Hong, and Rhee (1995) demonstrated that pervaporation is potentially applicable to the removal of the water produced from various enzymatic processes for the synthesis of several esters. Therefore, they studied the lipase-catalyzed (Lipozyme(R)) esterification reaction of oleic acid with n-butanol in isooctane to produce n-butyl oleate. An R2-type ISU-PVMR, using a dense polymeric membrane of cellulose acetate to remove water, was set. Oleic acid conversion was improved from the equilibrium value of 61.1—91%.
