METHOD FOR SYNTHESISING GLYCOLIC ACID |
| 摘要 |
The invention relates to a method for synthesising glycolic acid or one of the salts thereof, including the following step: placing glycerol and an oxidising agent in contact with one another in a reaction medium in the presence of a silver-based catalyst on a substrate, said substrate including a material selected from the group consisting of CeO2, basic Al2O3 optionally doped with a calcium or cerium oxide, an amphoteric resin, ZrO2, and a mixture of said materials. The invention also relates to the use of a silver-based catalyst on a substrate that can be used in said method. |

1. A process for the synthesis of glycolic acid or one of its salts comprising the following step:
bringing glycerol and an oxidizing agent into contact in a reaction medium in the presence of a catalyst based on silver on a support, said support comprising a material chosen from the group consisting of CeO2, basic Al2O3, optionally doped with a calcium or cerium oxide, an amphoteric resin, ZrO2 and a mixture of these materials. |
