Kinetic Studies of the Catalytic Oxidation of Toluene to Benzoic Acid in the Liquid Phase
The catalytic oxidation of toluene to benzoic acid in the liquid phase has been studied in an un-stirred tank reactor. Low concentration of acetic acid was added in order to increase the solubility of the catalyst in toluene. The dependence of the rate of reaction on the concentration of toluene catalyst and oxygen pressure was studied. It has been suggested that liquid phase oxidation of t...
متن کاملLiquid-Phase Oxidation of p-Xylene using N-Hydroxyimides
In this communication, we describe p-xylene oxidation with molecular oxygen at 373 K and atmospheric pressure using N-hydroximide catalysts. p-Xylene conversion was rather high over the first 2 h of reaction and complete by the end of the experiment. The product distribution curves versus reaction time are typical of consecutive reactions. The main intermediate product is p-toluic acid. Peak co...
متن کاملAg/ZnO Nanocomposites: Preparation, Characterization and Investigation of the Catalytic Activity for Oxidation of Toluene in Liquid Phase
In this research, Ag/ZnO nanocomposites were prepared and characterized by transition electron microscopy (TEM), the energy dispersive X-ray spectrum (EDS) and X-ray diffraction patterns (XRD). These nanocomposites were used as catalysts for the oxidation of toluene to benzaldehyde and benzoic acid with hydrogen peroxide (H2O2) and tert-butylhydroperoxide (TBHP) as oxidizing agent in the liquid...
متن کاملStatistical 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...
متن کاملPd on carbon nanotubes for liquid phase alcohol oxidation
Pd nanoparticles supported on carbon nanotubes (CNTs) showed a higher selectivity than Pd nanoparticles supported on activated carbon (AC) in the liquid phase oxidation of benzylic alcohol to benzaldehyde. Under solventless conditions a significant improvement in selectivity was observed for Pd/CNTs, whereas using Pd/AC a considerable over-oxidation of benzaldehyde was observed. Differently fro...
