New Extra Large Pore Chromium Oxophenylphosphate: An Efficient Catalyst in Liquid Phase Partial Oxidation Reactions
A new supermicroporous chromium oxophenylphosphate (CPP-1) has been synthesized using phenylphosphonic acid (PPA) as phosphorus source under hydrothermal condition at 443 K without using any structuredirecting agent (SDA). The material has been characterized by powder XRD, FE SEM-EDS, TEM, TG-DTA, N2 sorption, XPS, FT IR, UV-Vis spectroscopic techniques and CHN chemical analysis. CPP-1 showed s...

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...
متن کاملDirect 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...
