The system consisting of copper/zinc L ‐tartrate mixed crystals has been systematically explored in the whole range from pure copper tartrate to pure zinc tartrate. Mixed crystal L ‐tartrates were prepared and their thermochemical behaviour under oxygen was investigated. Oxidic precatalysts (CuO/ZnO) for catalytic tests in methanol synthesis were prepared by mild thermolysis of the mixed tartrates in air at 300 °C. Catalytic tests were performed with a multi‐channel parallel reactor. The catalytic activity shows a maximum at about equal amounts of copper and zinc whereas the specific surface area (BET surface) increases strongly when going from CuO to ZnO. This system offers a convenient, inexpensive route to CuO/ZnO precatalysts with adjustable compositions that avoids all other metals during preparation. (© Wiley‐VCH Verlag GmbH & Co.
