preparation | at present, the process of producing cyclohexanone and its analogs by phenol hydrogenation has attracted much attention. the process has the advantages of high selectivity of generated products, simple operation and high reaction efficiency. Therefore, the research on the process of phenol hydrogenation to cyclohexanone focuses on the research of high-efficiency catalysts. According to the research, the catalyst carrier plays a key role in the selectivity of the product. The introduction of acidic additives or the use of acidic carriers in the carrier can promote the reaction to the direction of cyclohexanone generation, thereby improving the phenol conversion rate and cyclohexanone selectivity. |
