ABSTRACT:
Starting from hydrolysable salts of at least one transition metal and at least one metal giving a refractory oxide in solution in a non-aqueous solvent, simultaneous hydrolysis of the salts is produced by the addition of an amount of water which corresponds substantially to that necessary for the stoichiometry of the reactions. Drying of the coprecipitate formed is effected in an autoclave under hypercritical conditions. Hydrogenation or controlled oxidation catalysts of greater activity are thereby produced.
