AMBROZIAK, K. ... et al, 2009. Greener and sustainable method for alkene epoxidations by polymer-supported Mo(VI) catalysts. 2nd International Congress on Green Process Engineering & 2nd European Process Intensification Conference, Lido Venice, Italy, 14-17 June
A 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.
