摘要： A catalyst for the production of hydrocarbon consists essentially of crystalline aluminum silicate, at least one compound of the metal zinc and/or cadmium and additionally silica. The catalyst is produced by heating a crystalline aluminum silicate, in a given case partially or completely converted to the hydrogen form, with a zinc and/or cadmium compound and molding with a silica containing binder.

摘要： There is described the working up of a solution by electrodialysis originally prepared by the enzymatic resolution of an N-acetyl-DL-aminocarboxylic acid. The electrodialysis device used consists of a plurality of three-chamber packets, each of which comprises a feed and diluent chamber (1), a (basic) concentrate chamber (2) located on its cathode side and an (acidic) concentrate chamber (3) located on its anode side, whereby each three-chamber packet is separated from each of the two adjacent ones by a device (4) in which water is decomposed into OH.sup.- ions and H.sup.+ ions. The added resolution solution is separated by this device into three solutions, the first of which contains the L-amino acid, the second of which contains the cations present in the resolution solution as hydroxides and the third of which contains the anions present in the resolution solution as free acids.
