A silver impregnation solution containing: (i) silver ions, (ii) a polar organic additive containing two to four carbon atoms and two to four functional groups selected from hydroxy, carboxylic acid, and amine groups, provided that a carboxylic acid group can only be present along with a hydroxy or amine group, and provided that an amine group can only be present along with a hydroxy or carboxylic acid group; and (iii) water; wherein components (i) and (ii) are water soluble and dissolved in the impregnation solution. Also described herein is a method for producing a catalyst effective in the oxidative conversion of ethylene to ethylene oxide, the method comprising subjecting a refractory carrier impregnated with the above-described silver impregnation solution to a calcination process. Also described herein is a method for converting ethylene to ethylene oxide by use of the foregoing silver catalyst, as produced by the above-described silver impregnation solution.
A silver impregnation solution comprising:
A silver impregnation solution consisting of:
A method for producing a catalyst effective in the oxidative conversion of ethylene to ethylene oxide, the method comprising subjecting a refractory carrier impregnated with a silver impregnation solution to a calcination process, wherein said silver impregnation solution comprises:
