Abstract
The invention relates to a method for synthesizing glycolic acid or one of the salts thereof, including the following step: placing glycerol and an oxidizing 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.
