Greener and sustainable method for alkene epoxidations by polymer-supported Mo(VI) catalysts
conference contribution
posted on 2009-08-04, 10:11 authored by Krzysztof Ambroziak, Rene Mbeleck, Basu Saha, David C. SherringtonA polybenzimidazole supported Mo(VI) (PBI.Mo) catalyst has been prepared and
characterised. The catalytic activities of the PBI.Mo catalyst in epoxidation of alkenes with tertbutyl
hydroperoxide (TBHP) as oxidant have been studied under different reaction conditions in
a batch reactor. As alkene representatives we have chosen cyclohexene, limonene, α-pinene and
1-octene as less reactive terminal alkenes.
The stability of each polymer catalyst was assessed by recycling a sample in batch reaction
using conditions that will form the basis of the continuous process. The loss of Mo from each
support has been investigated by isolating any residue from the reaction supernatant solutions,
following removal of the heterogeneous polymer catalyst, and then using the residues as
potential catalysts in epoxidation reactions.
