چکیده
|
Vanadium supported on highly ordered nanoporous silica (vox- lus-1) was synthesized and characterized by xrd, nitrogen adsorption desorption isotherms and uv-visible spectrophotometer. direct oxidation of benzene to phenol in liquid phase by h2o2 peroxide was examined by using various solvents (methanol, acetone, acetic acid, acetonitryl). the maximum yield (25%) and selectivity (73%) of the phenol produced were obtained in the presence of acetic acid. the catalyst can be reused for several times without any appreciable loss of activity.
