Direct Oxidation of Benzene to Phenol in Liquid Phase over Nanoporous Silica of Chromium-LUS-1
(Received: May 18, 2012; Accepted in Revised Form: February 4, 2013) Abstract: Direct oxidation of benzene to phenol in liquid phase in the medium of methanol, acetone, acetic acid and acetonitrile as a solvent over chromium catalyst supported on highly ordered nanoporous silica (Cr-LUS-1) by H O were examined. The best results obtained from methanol solvent with 20% yield and selectivity of 90...
متن کاملSynthesis and characterization of VOx/LUS-1 nanoporous silica and application for direct oxidation of benzene to phenol
The VOx/LUS-1 nanoporous silica synthesis and characterized by XRD, Nitrogen adsorption–desorption isotherms and UV-visible spectrophotometer. Direct oxidation of benzene to phenol in liquid phase by H2O2 peroxide were examined by using various (methanol, acetone, acetic acid, acetonitryl) solvents.
متن کاملDirect oxidation of benzene to phenol in liquid phase by H2O2 over vanadium catalyst supported on highly ordered nanoporous silica
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 were examined by using various solvents (methanol, acetone, acetic acid, acetonitryl). The maximum yield (25%) and selectivity (73%) of the ph...

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 were examined by using various solvents (methanol, acetone, acetic acid, acetonitryl). the maximum yield (25%) and selectivity (73%) of the ph...
متن کاملImprovement in Immobilization of Bread Yeasts by Sol-gel Method Combined with Functionalized Nanoporous Silica (LUS-1)
In this work, the effect of immobilization of bread yeast (Saccharomyces cerevisiae) by sol-gel technique combined with functionalized nanoporous silica was investigated in different weight ratios of silica containing materials (TMOS: LUS-1). The activities of immobilized yeast in days after immobilization were examined. The results showed immobilization maintain the yeast life for a longer tim...
