Abstract
Official abstract text for this publication.
Process for producing a supported silver catalyst, which comprises (a) reacting oxalic acid with an alkali metal base in a solvent, preferably water, to the second equivalence point of oxalic acid to give alkali metal oxalate; (b) reacting the alkali metal oxalate obtained according to (a) with silver salt in a solvent, preferably water, to give silver oxalate; (c) forming a complexation of the silver oxalate obtained according to (b) with a diamine compound in a solvent, preferably water, to give a diamine-silver oxalate complex.
