Process for the preparation of a catalyst for the oxidation of propylene and acrolein, and its use for the preparation of acrylic acid and acrolein

摘要

Catalyst for the oxidation of propylene and acrolein. The catalyst is prepared by precipitation from soluble salts of silver and molybdenum in quantities such as to obtain a molar silver oxide/molybdenum oxide ratio of 0.1 to 2.0, in the precipitate after drying and activation in air at 300 DEG -600 DEG C. Use in the production of acrylic acid and acrolein by vapour-phase oxidation of acrolein and/or propylene.
