Alkenes are readily hydrogenated under pressure in presence of a catalyst.
R – CH = CH2 + H2 R-CH2-CH3
The following catalysts have been used satisfactorily in the above reaction.
(i) Finely divided platinum and palladium are effective at room temperature. Platinum or palladium black i.e., metals in a very finelly divided state, may be prepared by reducing their soluble salts with (formaldehyde).
(ii) Nickel requires a temperature of 200–300°C. Raney nickel is effective at room temperature. Platinum or and atmospheric pressure. (The method for the preparations of Raney nickel has been described elsewhere in the module).
