ABSTRACT: This paper reports a kinetic model for the self-epoxidation of oleic acid with toluene as solvent and Novozym 435 (a commercially available preparation of immobilized Can-dida antarctica lipase) as catalyst at 30°C. The effects of various parameters on the conversion and rates of reaction...

| Summary: | ABSTRACT: This paper reports a kinetic model for the self-epoxidation of oleic acid with toluene as solvent and Novozym 435 (a commercially available preparation of immobilized Can-dida antarctica lipase) as catalyst at 30°C. The effects of various parameters on the conversion and rates of reaction were stud-ied. Both the initial rate and the progress curve data were used to fit an ordered bi-bi model. At low temperatures, the rate of epoxidation was faster than the rate of deactivation of the en-zyme by hydrogen peroxide. |
