Abstract: A method for the deoxofluorination of a ketone for the production of a geminal difluoride compound in an industrial scale comprising the following steps: preparing an educt mixture comprising a ketone and a dialkylaminosulfur trifluoride, letting flow the educt mixture into a reaction chamber of defined length, diameter and volume, with a flow path having a width perpendicular to the direction of the flow in the range of 1-10 mm, at a temperature of at least 75° C. up to 120° C., preferably between 80 and 100° C., to perform the deoxofluorination reaction and obtaining a product mixture to quench the product mixture with a basic aqueous solution in a cooled reservoir vessel.

Abstract: The invention relates to a multi-stage method for producing gas-filled microcapsules. In one stage of the method, the substance that forms the coat is polymerized. The microcapsules are formed in a physically and/or temporally separate stage, by means of a structuring process. The polymerization is carried out with moderate stirring, while the microcapsules are structured in dispersing conditions.
