PROCEDURE FOR THE RENEWAL OF OXIDISATION CATALIZERS |
| abstract |
The present invention relates to a process for the regeneration of a cobalt-based oxidation catalyst and possibly manganese and nickel from the Witten-DMT process used to oxidize the mixture containing p-xylene and / or p-toluic acid methyl ester in the liquid phase with oxygen or gas containing oxygen at 4 ... 6 atm and the temperature of 140 ... 170 ° C, subjecting the distillation residue to water, diluted mineral acids, warm and aqueous extract process. |
