Abstract
Silver/transition metal catalysts are made by calcining the polysilver salt of a polycarboxylic acid and at least one transition metal salt of an organic polycarboxylic acid at temperatures from 200.degree.-500.degree. C., and oxidizing the said calcined salts with oxygen at temperatures from 20.degree.-500.degree. C.
Claims11
A silver/transition metal catalyst obtained by calcining the polysilver salt of a polycarboxylic acid and at least one transition metal salt of a polycarboxylic acid at temperatures from 200.degree.-500.degree.C under an inert gas and oxidizing the said calcined salts with oxygen at temperatures from 20.degree.-500.degree.C, the said polysilver salt being selected from the group consisting of aromatic polycarboxylic acids and heterocyclic polycarboxylic acids and the transition metal of said transition metal salt being selected from the group consisting of the metals of Groups IV-B, V-B, VI-B, VII-B, VIII and I-B of the Periodic Table.
