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.

Electrolysis cell for producing alkali metal

A process for carrying out a liquid/solid reaction comprises The process has the advantage that the insoluble reaction product is obtained in a readily filterable form.

Process for liquid/solid reaction

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.

Process for preparing polyether polyols

Described is a process for the preparation of a particulate tetrahydro-3,5-dimethyl-1,3,5-thiadiazine-2-thione product by combining a first aqueous solution comprising methylammonium N-methyldithiocarbamate with a second aqueous solution comprising formaldehyde, followed by separation and drying of the resulting solid, which comprises combining the first and the second aqueous solutions in such a way that the ratio between the concentrations of dithiocarbamate functions and of formaldehyde is essentially constant in the reaction mixture over time during the duration of the reaction.
