A catalyst comprising a carrier, rhodium and at least one element selected from the group consisting of tin, germanium and lead is prepared from a rhodium compound and an alkyl, cycloalkyl or aryl tin, germanium or lead compound.

Process for manufacturing a catalyst comprising rhodium and at least one

Alcohols and particularly fatty alcohols are manufactured by hydrogenolysis of carboxylic esters in the presence of a catalyst comprising a carrier, rhodium and at least one second element selected from the group consisting of tin, germanium and lead. The rhodium content is from 0.1 to 5% b.w. and the content of the second element is from 0.1 to 10% b.w.

Catalytic process for manufacturing alcohols by hydrogenolysis of

A secondary alcohol dissolved in a C.sub.12 to C.sub.20 paraffinic hydrocarbon substantially free of aromatics and of sulfur is dehydrogenated to the corresponding ketone at a temperature of 170.degree.-230.degree. C. in the presence of a catalyst of the Raney nickel type containing from 0.1 to 10% by weight of an additional metal consisting of copper, silver, gold, tin, lead, zinc, cadmium, indium or germanium, the ketone being preferably removed, as it is formed, from the reaction medium. A catalyst for use in the present process is provided.
