| titleOfInvention | Method for producing cyclohexanecarboxylic acid derivatives with a low proportion of by-products |
| abstract | The present invention relates to a method for producing at least one cyclohexanecarboxylic acid or a derivative thereof by bringing into contact at least one corresponding benzene polycarboxylic acid or a derivative thereof with a gas containing hydrogen in the presence of at least one shell catalyst containing an active metal selected from the group consisting of ruthenium, rhodium, palladium, platinum and mixtures thereof, applied onto a supporting material containing silicon dioxide, wherein the pore volume of the supporting material is 0.6 to 1.0 ml/g, determined by Hg porosimetry, the BET area is 280 to 500 m2/g, at least 90% of the pores present have a diameter of 6 to 12 nm, and 40 to 70 percent by weight of the active metal, relative to the total volume of said active metal, is present in the shell of the catalyst up to a depth of penetration of 200 µm. The materials are brought into contact at a maximum superficial velocity of 50 m/h. |
