Abstract:

Hydrous zirconia nanoparticles were covalently functionalized by 3-(trimethoxysilyl)-propylchloride and ethylenediamine to support VO(acac)2 complex. The prepared catalyst has been characterized by means of FT-IR spectroscopy, PXRD pattern, thermal analysis, elemental analysis, and scanning electron microscopy. Then it was used for the epoxidation of cis-cyclooctene. The catalytic procedure was subsequently investigated for each catalyst and followed by Gas-Liquid Chromatography. It was also applied repeatedly in the optimum reaction conditions to reveal its recycling ability. Then these conditions were used for successful epoxidation of other linear and non-linear alkenes.
