Abstract
The synthesis of carbonyl compounds by oxidation of alcohols is an important research area. A Pt/C catalyst was prepared by wet impregnation technique followed by characterization using X-ray diffraction, Fourier transform infrared spectroscopy as well as surface area and pore size analysis. It was then employed as catalyst for benzyl alcohol oxidation. The progress of oxidation reaction was monitored using GC. The oxidation data was analyzed using the nonlinear regression method using Polymath 5.1 software to analyze reaction kinetics. The rate constant and order of reaction were calculated as 9.28 × 10−6 mol L g−1s−1and 0.447, respectively. The rate law for oxidation of benzyl alcohol was proposed as
