  • Patent number: 10851274
    Abstract: A coolant mixture including water and at least one of the compounds chosen from 1-methoxy-2-propanol and 1-ethoxy-2-propanol in the proportions of the corresponding azeotrope or in near-azeotropic proportions. Such a mixture can be used as a heat-transfer fluid in a heat-exchange device, which can be incorporated into an aircraft or spacecraft. A method for obtaining a mixture by fractional distillation is also disclosed.

  • Patent number: 10836940
    Abstract: The present invention relates to a cooling mixture comprising a fluorinated compound and a non-fluorinated compound, wherein the fluorinated compound is a hydrofluoroether and the non-fluorinated compound includes a carbonyl function, which has a flash point no lower than 23° C. and which is characterised by having low relative volatility. The present invention likewise relates to the use of such a mixture as a coolant in a heat-exchange device.

  • Publication number: 20200323749
    Abstract: Disclosed is a microemulsion of oil-in-water type including, preferably consisting of, by weight relative to the total weight of microemulsion: • 70% to 94% of water, • 1% to 15% of at least one hydrophobic fragrancing substance, • 4% to 20% of at least one preferably volatile solvo-surfactant, and • 0.1% to 15%, preferably 1% to 13%, of at least one hydrotropic agent or at least one surfactant selected from anionic surfactants, cationic surfactants, amphoteric surfactants and non-ionic surfactants. The solvo-surfactant is selected from monoalkylated glycerol derivatives of following formula (I): wherein the “alkyl” group is a linear or branched alkyl group including from 1 to 8 carbon atoms, and R and R? are each independently H or a linear or branched alkyl group including from 1 to 5 carbon atoms, with the proviso that R is different from R?, and mixtures thereof.

  • Publication number: 20200179247
    Abstract: An oil-in-water microemulsion including, in weight percentages: between 70% and 94% of water; between 1% and 15% of at least one perfumed hydrophobic substance; between 4% and 20% of at least one preferably volatile solvo-surfactant, which is a monoalkylated glycerol derivative of formula (I); and between 0.1% and 15% of at least one anionic surfactant and at least one alkyl glucoside as a hydrotropic agent. The microemulsion can therefore be used to produce a fine fragrance composition or a cosmetic or personal hygiene composition.

  • Patent number: 6956137
    Abstract: The invention relates to a method for oxidizing organic substrates using 1O2 in which hydrophobic organic substrates that react with 1O2 are added to an organic solvent in the presence of a heterogeneous or homogeneous catalyst with 30–70% being compr Afterwards, H2O2 is catalytically decomposed into water and 1O2, and the oxidation into corresponding oxidation products ensues.

  • Patent number: 6486360
    Abstract: The invention relates to a method for oxidizing organic substrate by using 1O2. According to the inventive method, organic substrates that react with 1O2 are mixed with 30-70% H2O2 in water, in an organic solvent or in a mixture thereof in the presence of a lanthanide as the catalyst. H2O2 is catalytically decomposed to water and 1O2 and is then oxidized to the corresponding oxidation products.
