PCT No. PCT/EP97/00601 Sec. 371 Date Aug. 5, 1998 Sec. 102(e) Date Aug. 5, 1998 PCT Filed Feb. 10, 1997 PCT Pub. No. WO97/30014 PCT Pub. Date Aug. 21, 1997A phosphorus-doped silver catalyst fixed bed is obtainable by I. arranging silver crystals obtained by electrolytic deposition of silver from an aqueous silver salt solution to form a starting silver catalyst fixed bed, II. producing an activated silver catalyst fixed bed from the starting silver catalyst fixed bed by passing through the latter, at from 150 to 800 DEG C., a gas mixture comprising methanol and oxygen (gas mixture M), and III. bringing the activated silver catalyst fixed bed into contact with from 1 to 20,000 ppm by weight of phosphorus, based on the silver, in the form of a finely divided phosphorus compound having a melting point or decomposition temperature of more than 500 DEG C. (phosphorus compound P).
