The invention more particularly relates to the use of a Raney-nickel based catalyst with rhodium and/or iridium.

Commercially available Raney nickel has an average Ni surface area of 100 m2 per gram of catalyst.

Commercially available Raney nickel has an average nickel surface area of 100 m² per gram of catalyst.[2]

Commercially available Raney nickel has an average nickel surface area of 100 m² per gram of catalyst.[2]

Care should be taken when handling these raw materials during laboratory preparation of Raney nickel.

Commercially available Raney nickel has an average Ni surface area of 100 m2 per gram of catalyst.[7]

The method is characterized by placing in suspension Raney nickel in a solution, preferably acid, of the metallic addition element.

Preferably, the catalyst is a Raney nickel or Raney cobalt catalyst which has been pretreated with an alkali metal alkanolate or an earth alkali metal alkanolate such as sodium or potassium methanolate.

This reagent behaves like Raney Nickel, comprising an efficient system for hydrogenation of unsaturated carbonyl compounds.

Cayenne cream may also cause irritations to the eyes and nose if contact occurs.

In the laboratory, nickel is frequently used as a catalyst for hydrogenation, most often using Raney nickel, a finely divided form of the metal alloyed with aluminium which adsorbs hydrogen gas.

The invention relates to a method for producing anis alcohol (methoxybenzyl alcohol) by hydrogenating anisaldehyde (methoxybenzaldehyde) in the presence of Raney nickel and of an alkaline additive.

As catalyst, we can use platinum (Pt), Raney’s Nickel (Ni) and Palladium on C (Pd/C).

Ni-Al alloys are used for magnets and catalyst production (e.g., Raney nickel).
