    Abstract: Provided is a method for preparing glycolic acid which comprises oxidizing glycolaldehyde with molecular oxygen in the presence of a solvent and a supported catalyst. Said supported catalyst comprises (i) a noble metal selected from the group consisting of Pt, Pd, Ru and Rh, (ii) Bi and (iii) a support. Advantageously, the supported metallic catalyst is more active than the catalysts used in prior art. Furthermore, the catalyst is more stable at oxygen rich conditions.

    Abstract: The invention relates to a composition C which comprises, in an aqueous medium M: surfactants suitable for creating a foam in the presence of a gas; and polymers P based on acrylamide or acrylamido units, having a molecular mass of 1,000,000 to 20,000,000 g/mol; or: composition C has a viscosity of less than 6 mPa·s; and the content of polymer P is greater than the concentration limit beyond which the apparent viscosity of a foam obtained from composition C is greater by at least 10% than the apparent viscosity of a foam obtained from the same composition but deprived of polymers. The invention further relates to the use of these compositions as foaming compositions for EOR.
