    摘要： The invention relates to a process for distillative workup of a methanol/water mixture, in which a methanol/water mixture is added to a distillation column (1), an essentially methanol-comprising vapor stream is withdrawn at the top of the distillation column (1) and an essentially water-comprising bottom stream at the bottom of the distillation column (1), at least a portion of the essentially methanol-comprising vapor stream is compressed and the compressed vapor stream is added as heating vapor to an evaporator (11) in which at least a portion of the methanol/water mixture to be separated is evaporated. The invention further relates to a process for preparing alkali metal methoxides in a reaction column (31) by adding methanol and alkali metal hydroxide solution to the reaction column (31), withdrawing alkali metal methoxide dissolved in methanol at the lower end of the reaction column (31) and withdrawing a methanol/water mixture at the upper end of the reaction column (31), and working up the methanol/water mixture by the process for distillative workup.

    摘要： 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.

    摘要： The present invention relates to a process for preparing largely HBr-free HCl gas and largely HBr-free aqueous HCl solution, which comprises the following steps: a) providing HBr-containing HCl gas; b) passing the HBr-containing HCl gas through aqueous HCl solution saturated with HCl; c) separating off HBr-containing aqueous HCl solution saturated with HCl; d) if desired, passing the largely HBr-free HCl gas obtained in step b) into water to obtain largely HBr-free aqueous HCl solution; with largely HBr-free aqueous HCl solution produced in step d) being able, if desired, to be recirculated to step b) of the process. The process of the present invention allows high-purity aqueous HCl solution for use in the semiconductor industry to be prepared inexpensively and on an industrial scale. However, the purified HCl gas obtained by means of steps a) to c) can also be used for any other purposes. The invention likewise provides an apparatus for carrying out the process of the present invention.
