  • Patent number: 9695366
    Abstract: The invention relates to novel demulsifiers for use in the demulsification of oils from water and vice versa, including the demulsification of crude oil from sea water or brine. In particular, the present invention relates to novel demulsifiers which are environmentally friendly, or ‘green’, and which can be used without restriction on-site in offshore oil drilling fields, for example in the North Sea. The novel demulsifiers are based on the reaction product of alkoxylated polyols or polyol esters with dicarboxylic acids.

  • Patent number: 9023329
    Abstract: Polyester oil structurants are obtainable by the reaction of a C4 to C10 Q dicarboxylic acid, a polyol and a C16 to C30, particularly a C20 to C24, monocarboxylic fatty acid. The structurants can be used to provide structure, particularly thickening and/or gelling, in oils of a wide range of polarity. Thickened oils can find application in a range of personal care and other applications.

  • Patent number: 8722814
    Abstract: Polyglycerol carboxylic acid esters are made by reaction of a, typically C2 to C30, particularly C6 to C22, carboxylic acid with glycerol carbonate, particularly with base catalyst, and desirably at temperatures from 170° C. to 250° C. Other carbonates e.g. cyclic diol carbonates such as ethylene or propylene carbonates, may be used in combination with the glycerol carbonate to make novel mixed polymeric esters. The molar ratio of carboxylic acid group to glycerol carbonate is typically from 2 to 30, but can be up to 100. The base catalyst is desirably alkali metal hydroxide, carbonate or alkoxide. The reaction is desirably carried out in an inert atmosphere, and reducing agent such as phosphorous acid, hypophosphorous acid or borohydride and/or activated carbon, may be included to improve product color.

  • Patent number: 8536349
    Abstract: A process of preparing cyclic ethers is described. The process involves the reaction of at least one organic compound such as a dioi or a polyol which it has at least one pair of hydroxyl groups separated by 4 or 5 carbon atoms, and which is capable of being converted into an ether linkage, with an organic carbonate in the presence of a base. The base is an alkoxy, a carbonate or a hydroxide base or is a mixture of such bases. At least one of the hydroxyl groups of the organic compound is not a tertiary hydroxyl group.
