  • Dewatering of thermochemical oil
    Patent number: 11981874
    Abstract: A process for dewatering a thermochemical oil. The process comprises providing a thermochemical oil comprising water; adding a solvent selected from mesityl oxide, 2-methyltetrahydrofuran, dioxane and furfural to the thermochemical, oil, to form a mixture comprising the thermochemical oil and the solvent; heating the mixture to remove an azeotrope comprising water and the solvent from the mixture, thereby forming a dewatered thermochemical oil. A dewatered thermochemical oil. A fuel precursor.
    Type: Grant
    Filed: June 4, 2020
    Date of Patent: May 14, 2024
    Assignee: PREEM AKTIEBOLAG
    Inventors: Anne-Charlotte Hällgren, Nils Anders Nilsson, Tomasz Janosik

  • Compounds suitable as precursors to compounds that are useful for imaging amyloid deposits
    Patent number: 8653274
    Abstract: The present invention relates to novel derivatives that are suitable as precursors to compounds that are useful for imaging amyloid deposits in living patients, their compositions, methods of use and processes to make such compounds. The compounds deriving from these precursors are useful in methods of imaging amyloid deposits in brain in vivo to allow antemortem diagnosis of Alzheimer's disease by positron emission tomography (PET) as well as measuring clinical efficacy of Alzheimer's disease therapeutic agents. Furthermore, the present invention also discloses the precursor compounds in crystalline form.
