  • METHOD FOR THE PREPARATION OF BIS(FLUOROSULFONYL)-IMIDE AND OF ITS SALTS
    Publication number: 20180362343
    Abstract: The invention relates to a method for the preparation of bis(fluorosulfonyl)-imide, the method starts from bis(chlorosulfonyl)-imide or its respective derivatives, which is reacted with HF in the presence of chlorosulfonyl isocyanate, and uses a certain extraction step for extraction of bis(fluorosulfonyl)-imide from an aqueous solution; the invention is also useful for the preparation of certain salts of bis(fluorosulfonyl)-imide and its derivatives.

  • METHOD FOR ISOLATING OILS FROM CELLS AND BIOMASSES
    Publication number: 20110159167
    Abstract: The present invention relates to a process for the isolation of oils from cells, characterized in that the emulsion produced after the decomposition of the cells by high-pressure homogenization is demulsified. Any desired fatty acid compositions or oil compositions can be obtained in one simple step by mixing different biomasses and optionally adding further oils in an excess.

  • INTEGRATED METHOD FOR PRODUCING TRIOXANE FROM FORMALDEHYDE
    Publication number: 20100152466
    Abstract: The invention relates to an integrated process for preparing trioxane from formaldehyde in which a stream A1 comprising water and formaldehyde and a recycle stream B2 consisting substantially of water and formaldehyde are fed to a trioxane synthesis reactor in which the formaldehyde is converted to trioxane to obtain a product stream A2 comprising trioxane, water and formaldehyde; stream A2 is fed to a first distillation column and distilled at a pressure in the range from 0.1 to 2.5 bar to obtain a stream B1 enriched in trioxane, and the stream B2 consisting substantially of water and formaldehyde; stream B1 and a recycle stream D1 comprising trioxane, water and formaldehyde are fed to a second distillation column and distilled at a pressure in the range from 0.2 to 17.5 bar to obtain a product stream C2 consisting substantially of trioxane, and a stream C1 comprising trioxane, water and formaldehyde; stream C1 is fed to a third distillation column and distilled at a pressure in the range from 0.1 to 2.
