Group II The activity drops more than the Ni surface concentration (Fig. 13), i.e., at least about 20 times. However, for several reactions this drop is two or more orders of magnitude. The reactions included in this group are methanation and Fischer-Tropsch synthesis, isomerization, de-hydrocyclization or hydrogenolysis of alkanes, ether formation from alcohols, metathesis of alkylamines, and possibly other reactions.

The preparation of ketones in particular of asymetrically substituted ketones from aldehydes is desirable since the latter are readily available, for example via the oxo-synthesis. Isomerizations of this type, for example over catalysts of mixed oxides containing tin, molybdenum and copper, are known. The disadvantages here are that only low selectivities are achieved at satisfactory conversions, and the best results with regard to selectivity and catalyst life can be obtained only with the addition of steam. Therefor, in the industrial production of asymmetrically substituted ketones, it was necessary to use the condensation of different organic acids with decarboxylation. In this process, the inevitable production of symmetrically substituted ketones and of carbon dioxide is a disadvantage. ATdol condensation with subsequent hydrogenation is another possibility but requires very often two reaction stages.
