Abstract

A novel and promising process for synthesizing cyclohexanone, a precursor of polyamide synthesis, via the comproportionation of phenol and cyclohexanol has been investigated. This process was studied within the temperature range of 200–300 °C with the initial substances being used in stoichiometric ratio. The Ni/Al₂O₃ catalysts, which were prepared using the deposition–precipitation method and characterized by ICP–AES, XRD (including in situ investigation), N₂ adsorption–desorption, H₂-TPR, CO pulse adsorption, and FTIR spectroscopy, were employed in this study. The present study established a correlation between conversions of phenol and cyclohexanol into cyclohexanone over Ni/Al₂O₃ catalysts and the accessible Ni⁰ surface area. Furthermore, kinetic analysis of the experimental data has demonstrated that the suggested Ni-based catalysts exhibit high activity in the explored process.

镍基催化剂上环己醇与苯酚转移加氢直接合成环己酮

研究了以苯酚和环己醇为原料合成聚酰胺前体环己酮的新工艺。该工艺在200-300℃的温度范围内进行了研究，初始物质按化学计量比使用。采用沉积-沉淀法制备的Ni/Al2O3催化剂，采用ICP-AES、XRD（包括原位研究）、N2吸附-脱附、H2-TPR、CO脉冲吸附和FTIR光谱对其进行了表征。本研究建立了苯酚和环己醇在Ni/Al2O3催化剂上转化为环己酮与Ni0可达表面积之间的关系。此外，实验数据的动力学分析表明，所建议的镍基催化剂在探索过程中表现出较高的活性。
