| titleOfInvention | 6-chloro-3-nitrotolyl-4-sulfonic acid liquid-phase hydrogenation catalyst and preparation method thereof |
| abstract | The invention relates to a 6-chloro-3-nitrotolyl-4-sulfonic acid liquid-phase hydrogenation catalyst and a preparation method thereof. The 6-chloro-3-nitrotolyl-4-sulfonic acid liquid-phase hydrogenation catalyst is characterized by comprising 0.05-0.5 wt% of alumina support and the balance of active component metal palladium supported on the alumina support; the metal palladium is distributed on the alumina support surface in an eggshell mode; the specific area of the catalyst is 100-240m<2>/g; and the pore volume of the alumina support is 0.5-0.9ml/g, and the specific area is 100-240m<2>/g. The preparation method comprises the following steps: after oxidizing, roasting and reducing raw materials under certain conditions, drying to obtain the finished catalyst product. The through selectivity of the catalyst is up to more than 96%, the specific productivity is up to 430, and the selectivity is up to more than 96%; and the supported amount of the noble metal palladium can be down to 0.2%, thereby well solving the problem of the relationship between the manufacturing cost and the catalyst performance. |
