More Information
Summary:The invention relates to a catalyst, particularly a catalyst for preparing p-acetaminocyclohexanol and a preparation method thereof. The invention has the advantages of mild reaction conditions, low catalyst consumption and high catalytic hydrogenation activity. The catalyst comprises a hydrogenation component and a support, wherein the hydrogenation component is metal ruthenium; the support is aluminum oxide, activated carbon, carbon nanotubes or silicon dioxide; and the supporting amount of the hydrogenation component is 1-4 wt%. The preparation method comprises the following steps: pretreating the support; proportionally impregnating the support in a ruthenium precursor salt compound water solution or ethanol solution for 12-24 hours, drying at 80-150 DEG C for 4-12 hours, and roasting in air at 300-500 DEG C for 2-6 hours, wherein the ruthenium precursor salt compound is Ru(NO)(NO3)3 or RuCl3; and reducing the roasted catalyst at 300-500 DEG C in hydrogen to obtain the product.
