 1525.    HÜTTIG, G. F., AND WEISSBERGER, E.  [Catalytic Activity of Platinum Metals in the Decomposition of Methanol.]  Siebert Festschr., 1931, pp. 173-178; Chem. Abs., vol. 26, 1932, p. 4233.

       Catalytic activity of metals of the Pt group deposited on asbestos on the reaction of MeOH→2H₂+CO is generally very erratic in the early stages of use but finally reaches a constant value that decreases in the order Pd, Os, Rh, Ru, Ir, Pt.  In the 1^st few hr. the activity of Os rises to more than 15 times its final constant value, then falls rapidly, whereas the values for Pd, Pt, and Rh undergo relatively little variation.  The ultimate values are in all cases much higher than that of a ZnO catalyst.
