Abstract
AbstractA new heterogeneous catalyst was prepared by grafting [MoO2(acac)2] on the hydroxyapatite (HAP) nanoparticle surfaces. The resulting catalyst, [MoO2(acac)]@HAP, was characterized by the powder X‐ray diffraction, FT‐IR spectroscopy, inductively coupled plasma/atomic emission spectroscopy, field emission scanning electron microscopy, energy‐dispersive X‐ray analysis, thermogravimetery analysis, and transmission electron microscopy techniques. The results obtained confirmed that the catalyst could be successfully used for the efficient epoxidation of olefins with tert‐butyl hydrogen peroxide in 1,2‐dichloroethane as the solvent. This heterogeneous catalyst could be reused for several times without a significant loss in its catalytic activity and with no significant reduction in the reaction yield. This novel material showed a great catalytic performance, and the reactions carried out using this catalyst showed a good‐to‐excellent yield, high purity of the desired products, and a short reaction time.
