    Abstract: A method for producing highly pure, easily flowable LiPF6 by crystallization of organic solvents, whereby LiPF6 is crystallized from a solution in an aprotic organic solvent 1, a second inert aprotic solvent 2 is added to this solution and the first solvent 1 is substantially distilled off. The invention also relates to the use of LiPF6 in the production of lithium batteries.

    Abstract: Modification of the cross-flow resistance of a diaphragm based on fibrous material comprises treating the diaphragm, during or after manufacture, with a dispersion of a component (I) containing fluorine and optionally a solution containing a zirconium dioxide (ZrO2) precursor. Preferably treatment is carried out during electrolysis. The amount of (I) used is 0.1-30 wt.% w.r.t. the fibrous material of the diaphragm and the amount applied is 30-500 g/m diaphragm surface area.

    Abstract: Alkali metal methoxides are prepared from aqueous alkali metal hydroxide, which may have been admixed with methanol, and methanol in a reaction column having at least 5, preferably from 15 to 30, theoretical plates between the feed point for the aqueous alkali metal hydroxide and the feed point for the methanol. The gaseous methanol/water mixture formed in the reaction is fractionated in a rectification column. In one variant of the invention, the trays chosen for the reaction column configured as a bubble cap tray, valve tray or sieve tray column are trays in which not more than 5%, preferably

    Abstract: An electrolysis device producing alkali metals from a liquid alkali metal heavy metal alloy, including at least two connected tubes forming an electrolysis unit. Two solid electrolyte tubes are arranged concentrically in each tube and oriented with openings towards one end of each tube such that a first annular gap for guiding a liquid alkali metal forming an anode is located between the inside of the tube and the outside of the solid electrolyte tubes. An alloy inlet and outlet for the liquid alkali metal in each of the tubes leads into the first annular gap of a tube. An inner chamber sealed off from the alloy inlet, first annular gap, and alloy outlet in each solid electrolyte tube receives liquid alkali metal that can be used as a cathode connected to the alkali metal outlet. Two respective closure devices are arranged at the two ends of each tube.
