چکیده
|
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.
