Abstract
A silver salt solution suitable for depositing silver on a support in the preparation of silver catalysts is made by reacting a silver compound with a neo-acid, in a hydrocarbon solvent. The reaction is completed under reflux conditions, thereby removing water formed by the reaction and reacting at least 90% of the unreacted acid. Therefore, the solution may be used without further processing to impregnate a porous support, thereby providing a catalyst useful for oxidation of ethylene oxide.
