The invention relates to a method for producing an alkali metal alcoholate solution L.sub.1 in an electrolysis cell E which comprises at least one cathode chamber K.sub.K, at least one anode chamber K.sub.A, and at least one central chamber K.sub.M lying therebetween. The interior I.sub.KK of the cathode chamber K.sub.K is separated from the interior I.sub.KM of the central chamber K.sub.M by a separating wall W comprising at least one alkali-cation-conductive solid ceramic electrolyte (=AFK) F (e.g. NaSICON). F has the surface O.sub.F. A part O.sub.A/MK of the surface O.sub.F directly contacts the interior I.sub.KM, and a part O.sub.KK of the surface O.sub.F directly contacts the interior I.sub.KK. The surface O.sub.A/MK and/or the surface O.sub.KK comprises at least one part of a surface O.sub.F. O.sub.F is produced from a pre-treatment step in which F is produced from an AFK F comprising the surface O.sub.F. In the pre-treatment step, AFK is removed from F by sputtering the surface O.sub.F using noble gas cations N+, and the AFK F with the surface O.sub.F comprising the surface O.sub.F formed by the sputtering process is obtained. During the electrolysis process for producing the alkali metal alcoholates with F instead of F, an improved conductivity is provided, whereby for a constant current density, a lower voltage can be used.

An apparatus for preparing dimeric and trimeric silicon compounds is provided. The apparatus includes a reactor for generating a nonthermal plasma; a collecting vessel in product flow communication with the nonthermal plasma reactor; and a series of at least three rectification columns in flow communication with the collecting vessel.
