Abstract: An electrolysis cell for preparing alkali metals from a liquid alkali metal heavy metal alloy, including a tube arranged essentially horizontally having a closure device at each of the two ends of the tube. At least one solid electrolyte tube arranged concentrically in the tube and oriented with openings towards one end of the tube such that a first annular gap for conducting a liquid alkali metal, which forms an anode, is present between the inside of the tube and the outside of the solid electrolyte tube. An interior space in the solid electrolyte tube, sealed off from an alloy inlet, first annular gap and an alloy outlet, accommodates liquid alkali metal that can be used as a cathode.

Abstract: A process for carrying out a liquid/solid reaction comprises a) preparing a reaction suspension in which a first reactant is present in suspended form and a second reactant is present in dissolved form in a suspension medium, where one of the reaction products is insoluble in the suspension medium, b) passing the reaction suspension through an elongated reaction zone so that the Reynolds number of the stream is less than 20,000 and c) separating off the insoluble reaction product formed. The process has the advantage that the insoluble reaction product is obtained in a readily filterable form.

Abstract: A process for preparing polyether polyols includes a precipitation step, a recrystallization step, and a reaction step. In the precipitation step, a multimetal cyanide compound is precipitated by reaction of a metal salt with a cyanometalate compound. In the recrystallization step, the multimetal cyanide compound precipitated above is recrystallized by adding further metal salt and/or further cyanometalate compound. The recrystallization forms a multimetal cyanide catalyst compound. In the reaction step, an initiator and one or more alkylene oxide are reacted in the presence of the multimetal cyanide catalyst compound.

Abstract: A method for the production of a particle-containing preparation of tetrahydro-3,5-dimethyl-1,3,5-thiadiazin-2-thione, by combination of a first aqueous solution containing methylammonium-N-methyldithiocarbamate with a second solution containing formaldehyde and separation and drying of the solid formed is disclosed. The invention is characterised in that the first and second solutions are combined such that over the duration of the reaction the ratio of the concentration of dithiocarbamate functions and formaldehyde in the reaction mixture remains essentially constant over time.
