Benzoic acidVOTPPIn this paper, two-step method was used to synthesize 5,10,15,20-tetraphenyl-21H,23H-porphine vanadium(IV) oxide (VOTPP) and toluene catalytic oxidation was explored. The result showed that this catalyst led to benzoic acid as the main product and successfully simulated the...
LOOP OXIDATION OF TOLUENE TO BENZOIC ACIDA process of liquid phase oxidation of a hydrocarbon compound involving injection of pure oxygen into a hquid hydrocarbon in a reaction vessel while maintaining the atmosphere of the reaction vessel headspace outside the explosion triangle for the oxygen-...
The modification of V2O5-Sb2O3/TiO2 catalyst was made to obtain excellent catalytic activities, in terms of toluene conversion, selectivity to benzoic acid and life for the subject reaction. A variety of oxides as second additives to a V2O5-Sb2O3/TiO2 catalyst were examined, and found that ...
Liquid-phase oxidation of toluene with air has become the main technology for producing benzoic acid in a reactor at present. Based on the kinetic model of... 张玉坤,李初福,何小荣,... - 《Chinese Journal of Chemical Engineering》 被引量: 27发表: 2008年 Co-VPO催化甲苯液相H2O2氧化制苯甲醛 ...
The oxidation reaction of para - izopropyltoluene to para - isopropyl benzoic acid is investigated in liquid phase in organic polar solvent, without cobalt acetate catalyst promoted by cyclohexanone or methyl ethyl cetone. It was especially followed the influence of some parameters such as: temperatu...
During the oxidation of toluene under semibatch conditions, the formation of benzyl alcohol is initially equal to the rate of formation of benzaldehyde. As the overall conversion increases the benzyl alcohol concentration at first decreases much faster than benzaldehyde, but this decrease slows down ca...
Direct Oxidation of Toluene to Benzoic Acid with Molecular Oxygen over Manganese Oxides Manganese oxides, which are easily prepared, simple to use and capable of being recycled, have been employed as catalyst in the selective oxidation of tolu... X Li,J Xu,F Wang,... - 《Catalysis Letters》...
This selective oxidation of toluene to benzyl alcohol, benzaldehyde and benzoic acid provides a step for removing toluene from wastewater or converting it into less harmful substances. Different parameters, e.g. the reaction time, temperature, pressure, the amount of catalyst and agitation, etc ...
Complete oxidation of toluene over bimetallic Pt-Au catalysts supported on ZnO/Al2O3 For instance, the oxidation of toluene was completed by NHPI combined with Co(OAc)2 under an oxygen atmosphere at room temperature to give benzoic acid ... Kim,J K.,Ahn,... - 《Applied Catalysis B》 被...
With thiolate-bound Fe porphyrins, the catalytic oxidation of inert substrates such as cyclohexane (into cyclohexanol and cyclohexanone) and toluene (into benzyl alcohol and p-cresol) was observed. This is one of the rare examples of electrochemically driven reactivity that mirrors the one of P450....
