| titleOfInvention | Method for recovering activity of glycolic acid production catalyst |
| abstract | (57) Abstract: In a method for producing glycolic acid by catalytic oxidation of ethylene glycol in the presence of a catalyst, the activity of a catalyst whose activity has been reduced by repeated use or continuous use for a long time can be easily and inexpensively. The challenge is to provide a way to recover. SOLUTION: The catalytic activity of ethylene glycol, which is reduced by catalytic oxidation of ethylene glycol with an oxygen-containing gas in the presence of a catalyst to produce glycolic acid, is 0.5 kg / kg lower than the oxygen partial pressure of the oxygen-containing gas in the catalytic oxidation reaction. A method for recovering the activity of the reduced catalytic activity, which comprises carrying out the catalytic oxidation reaction treatment at a high oxygen partial pressure of at least cm 2 . |
