Abstract: The present invention concerns a process of oxidizing an alcohol for the production of its corresponding carbonyl compounds wherein the oxidation is performed with oxygen or gases containing oxygen in the presence of a catalyst comprising at least a gold compound and a copper compound. Said alcohol oxidation by gaseous oxidant can achieve a high yield and selectivity with minimized degradation products or waste organic solvents.

Abstract: The present invention relates to a method for preparing an aqueous dispersion of water-soluble polymers, which comprises a step (E) of radical polymerization, wherein the following are brought into contact in an aqueous medium (M) in which the synthesised polymer is not soluble: at least one ethylenically unsaturated monomer which is soluble in the aqueous medium (M); at least one source of free radicals; and a reactive stabiliser which comprises: a polymer chain (CP) which is soluble in the medium (M), a group (G) providing the radical polymerization of step (E) with a living and controlled nature, such as, for example, a group carrying a thiocarbonylthio —S(C═S)— group.

Abstract: The present invention relates to the use of at least two phenol derivatives jointly with at least one ancillary polymerization inhibitor which is different from these two phenol derivatives and particularly is selected from phenol derivatives, amine derivatives, thiazine derivatives, nitroso compounds, N-oxyl derivatives, metal salts, quinone derivatives, and mixtures thereof, to inhibit the polymerization of ethylenically unsaturated monomers comprising at least one heteroatom, it being also possible for a dispersant to be incorporated. The present invention also relates to a corresponding polymerization-inhibiting composition and to the corresponding process for preparing ethylenically unsaturated monomers comprising at least one heteroatom, and particularly acrylic monomers.

Abstract: The invention provides a synergistic surfactant composition comprising: (a) a first amphoteric surfactant, which is selected from C8-C22 sultaines, salts thereof, and mixtures thereof; and (b) a second amphoteric surfactant, which is selected from C8-C22 betaines and salts thereof, C8-C22 propionates and salts thereof, and mixtures thereof. This surfactant composition may be used to generate foam that is used for unloading a liquid from a hydrocarbon reservoir. It may be that the liquid unloading of foam generated using the surfactant composition is greater than that of foam generated from the first and second surfactants when they are foamed individually.

Abstract: This invention relates to stable liquid formulations of the nitrification inhibitor nitrapyrin comprising polar solvents that are stabilized with small amounts of compounds which help to reduce the tendency of polar solutions of nitrapyrin to corrode metal surfaces. Many of the formulations disclosed herein exhibit useful physical, chemical, and bioactive properties including reduced levels of corrosion when in contact with ferrous metals.
