摘要： The present invention is directed to a process for synthesizing an internal ketone K1 by decarboxylative ketonization reaction of a fatty acid, a fatty acid derivative or a mixture thereof in a liquid phase with a metal compound as catalyst in a reaction medium, said process being characterized in that a ketone K2 at liquid state, which is identical or similar to the ketone K1, is introduced into the reaction medium. The so-synthesized internal ketone K1 can be used for the preparation of a variety of end compounds, including surfactants having a twin-tail structure or a Gemini structure.

摘要： The present invention relates to a method making it possible to ensure a gradual release of polymer chains within a liquid medium, said method comprising bringing said liquid medium into contact with specific solid objects formed by polymer chains soluble in the medium and carrying hydrophobic side groups ensuring physical crosslinking between said polymer chains within said solid objects.
The released chains may in particular be used as inhibitors of the formation of inorganic or organic deposits (scale inhibitors) within a liquid medium, typically in the field of oil extraction.

摘要： The present invention provides a device and method for testing wear and friction properties of different materials under various experimental conditions representative of real usage conditions. In general, the device according to the invention is based on contacting a sample with a rotating disk with intermittent contact, in “open cycle” conditions, where dynamic loads are applied to the sample for the contact to occur. The control of dynamic loading is fully independent of the disk rotation.

摘要： The present invention relates to a new process of vanillin production from a substrate by bioconversion and that allows a continuously producing and removing vanillin from the fermentation broth as it is formed. In particular, the invented process advantageously allows to reduce the residence time of vanillin in the fermenter and to maintain the vanillin concentration, in the fermentation broth, below its toxic level for the microorganism.

摘要： The present invention relates to the use of thermoplastic polymer compositions for impregnating reinforcing materials in the form of fabric or industrial fabrics for the manufacture of composite materials. The field of the invention is that of composite materials as well as molding/consolidation processes and obtained parts. The invention more particularly relates to a method of manufacturing a composite article by injection molding comprising at least the steps of introducing at least one reinforcement fabric into a preheated mold, partial closure of the mold, a temperature rise step of the mold, optionally a step of maintaining the temperature of the mold before injection of a thermoplastic polymer composition, a step of injecting a thermoplastic polymer composition into the mold, a step of mold closure to the final part thickness allowing the flow of the resin through the reinforcing fabric, a cooling step and a recovery step of the obtained composite article.
