Abstract: A method for oxidation of glycerol into glyceric acid is described, which includes a step of treating glycerol with a supported metal catalyst in the presence of oxygen, said catalyst including platinum and a metal element selected from the group comprising tin, molybdenum, bismuth and a mixture thereof.

Abstract: A method for synthesising a second ester from a first ester, the method including the following steps: a) placing a first ester and a catalyst in the presence of dihydrogen such as to obtain a first alcohol and a second alcohol; b) extracting the second alcohol from the reaction medium; c) reacting the first alcohol with the catalyst of step a) in order to obtain a second ester and dihydrogen; and d) recirculating the dihydrogen obtained in step c) by injecting same into step a).

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.

Abstract: The invention relates to a method for the hydroformylation of triglycerides by homogeneous catalysis in the presence of at least one substituted cyclodextrin, said method comprising a step a) of combining, under agitation, at least one catalyst, water, at least one unsaturated triglyceride and said substituted cyclodextrin, in the presence of gaseous hydrogen and carbon monoxide, said step being carried out in reactive conditions allowing the formation of an emulsion during the agitation and a decanting of the products once the agitation has stopped.

Abstract: Biocompatible reservoirs are constituted by collagen, optionally associated with mucopolysaccharides and/or gelatin; these reservoirs can be filled with an active principle which does not have to be mixed with collagen. The reservoirs can be employed to either hold or to emit one or more active principles in order to concentrate same and/or to distribute same at a controlled rate "in vitro" and/or "in vivo". The reservoirs thus are enclosed vessels of conseration of "in vitro" or "in vivo" cultures of cells, bacteria or viruses.
