摘要: A polybenzimidazole supported Mo(VI) (PBI.Mo) catalyst has been prepared and characterised. The catalytic activities of the PBI.Mo in epoxidation alkenes with tert-butyl hydroperoxide (TBHP) as an oxidant have studied under different reaction conditions a batch reactor. As alkene representatives we chosen cyclohexene, limonene, α-pinene 1-octene (a less reactive terminal alkene). order reactivity was found to be: cyclohexene>limonene>α-pinene>1-octene. stability each polymer assessed by recycling sample using that will form basis continuous process. loss Mo from support investigated isolating any residue supernatant solutions, following removal heterogeneous catalyst, then residues potential catalysts reactions.
