An efficient green approach for the biocatalytic epoxidation of fatty compounds derived from soyadeodistillate using Fermase CalB enzyme with hydrogen peroxide under acid free conditions is described. To the best of our knowledge this is the first report on the chemoenzymatic epoxidation of fatty esters having branched alkyl chain without using additional acid as an oxygen carrier. After completion of the reaction the immobilized enzyme catalyst was easily recovered by filtration and reused for successive four runs with the marginal loss in catalytic activity.

Oxo-vanadium Schiff base was covalently immobilized onto chemically functionalized graphene oxide (GO) using 3-aminopropyltriethoxysilane as a coupler. The loading of vanadyl Schiff base onto GO nanosheets was confirmed by FTIR, XRD, TGA, and inductively coupled plasma-atomic emission spectroscopy (ICP-AES). The synthesized heterogeneous catalyst was found to be efficient and selective for the epoxidation of fatty acids and esters using t-butyl hydroperoxide (TBHP) as an oxidant. Interestingly, the immobilized catalyst showed a higher catalytic efficiency than the homogeneous vanadyl acetylacetonate. The recycling experiment results indicated that the catalyst was highly stable and maintained very high activity, and selectivity even after being used for six cycles.
