71. BADER, W., GREEN, S. J., AND BRITISH CELANESE, LTD. Catalyst for Methanol Synthesis. British Patent 300,142, May 2, 1927. Chem. Abs., vol. 23, 1929, p. 3479.

Catalysts for MeOH synthesis are prepared by precipitating ZuCO₃ in gelatinous form, washing and drying the precipitate so that it retains its colloidal state, and heating the gel at a temperature not exceeding that employed in the MeOH synthesis. Protective colloids also may be used. Gives various details and examples.
