In this work the performance of the classical catalytic system VO acac 2/tert-butylhydroperoxide was eVO acac 2/tert-butylhydroperoxideolydienes.
The catalytic activities of the prepared catalysts were evaluated through the epoxidation of cyclohexene using TBHP as oxidant.
These samples were characterized (with XRD, ICP, nitrogen adsorption, FT-IR, ESCA, and TEM) and evaluated for the epoxidation of propylene with two alkyl hydroperoxides.
The catalytic performance of each catalyst was evaluated by following the epoxidation of styrene, employing tert-butyl hydroperoxide as the oxidant and CH3CN as the solvent.
The interest in the epoxidation of vegetable oils is constantly growing in the chemical industry.
Less promising results were obtained in the epoxidation of (R -limonene.
Especially, in the epoxidation of α-methylstyrene, both the conversion and enantiometric excess (ee) could exceed 99%.
This indicates that surface titanol groups might be involved in the epoxidation of trans-stilbene.
ABA1 encodes zeaxanthin epoxidase which plays a role in the epoxidation of zeaxanthin to antheraxanthin and all-trans-violaxanthin in the ABA biosynthetic pathway.
In that light, the epoxidation of unsaturated fatty acids is very interesting as it can provide diverse side chains arising from the mono- or di-epoxidation of the unsaturated fatty acid.
