New Extra Large Pore Chromium Oxophenylphosphate: An Efficient Catalyst in Liquid Phase Partial Oxidation Reactions
نویسندگان
چکیده
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 specific surface area of 313 m 2 g -1 with extra large supermicropores having dimension of ca. 1.4 nm. TEM result suggested lamellar type pore-wall structure for this material. It exhibited good catalytic property in partial oxidation of olefins in presence of tertbutylhydroperoxide (TBHP) as oxidant.

Statistical Optimization of Liquid Phase Oxidation of Benzyl Alcohol over Efficient Cobalt Promoted Vanadyl Pyrophosphate Catalysts by Box-Behnken Design
Vanadium phosphorus oxides (VPO) has been applied as a heterogeneous catalyst in gas phase oxidation reactions and its application is very limited in liquid phase. In this study a series of cobalt-doped vanadium phosphorus oxides (VPO-Co) catalysts with different loading of Co (0.01-1.0 mol ratio of Co/V) were prepared. Oxidation of benzyl alcohol was studied in the liquid phase over VPO and VP...

Nanomagnetic MgFe2O4 is an active, stable, and reusable catalyst for the oxidation of alcohols. The oxidation of various primary and secondary alcohols has been examined and related corresponding products were obtained in good yields. The reactions were carried out in the presence of water as solvent and oxone (at room temperature) or H2O2 (at 60 ºC) as an oxidant. The catalyst was investigated...
