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...
متن کاملCataliticoxidation of benzyl alcohol by Cu(II) polypyridyl complexes
Two polypyridyl copper(II) complexes, [Cu(phen)(phen-dione)Cl]Cl (1) and [Cu(bpy) (phen-dione)Cl]Cl (2), (where Phen =1,10-phenanthroline, bpy =2,2'-bipyridine and Phen-dione = 1,10-phenanthroline-5,6-dione), were used as efficient catalysts for the oxidation of benzyl alcohol to benzaldehyde. The effects of various parameters such as reaction temperature, reaction time, etc. were studied. The ...
متن کاملTuning the Synthesis of Manganese Oxides Nanoparticles for Efficient Oxidation of Benzyl Alcohol
The liquid phase oxidation of benzyl alcohol is an important reaction for generating benzaldehyde and benzoic acid that are largely required in the perfumery and pharmaceutical industries. The current production systems suffer from either low conversion or over oxidation. From the viewpoint of economy efficiency and environmental demand, we are aiming to develop new high-performance and cost-ef...
متن کاملStatistical modelling and analysis of the aerobic oxidation of benzyl alcohol over K-Mn/C catalysts
We report the application of statistical multivariate analysis to optimize the process parameters (including temperature, O2 pressure, concentration of benzyl alcohol, Mn content, and K:Mn molar ratio) in the oxidation of benzyl alcohol using molecular oxygen over K-Mn/C catalysts. This multi-regression model, based on 38 experimental runs, shows reasonably accurate prediction on the benzyl alc...
متن کاملPreparation of halloysite nanotube-supported gold nanocomposite for solvent-free oxidation of benzyl alcohol
Gold nanoparticles supported on halloysite nanotubes (Au/HNTs) were prepared by a homogeneous deposition-precipitation method. The specific characteristics of the catalyst were characterized in detail, in relation to their performance for solvent-free oxidation of benzyl alcohol. The particular structure of the catalyst resulted in high catalytic activity and stability compared with other suppo...
