Process for producing acrylic acid by vapor-phase oxidation by heterogeneously catalyzed propene with molecular oxygen in a reaction zone

摘要

A method of producing acrylic acid by vapor-phase oxidation by heterogeneously catalyzed propene with molecular oxygen in a reaction zone, in this case, the catalytically active composition of Sb elements Mo, V, Te and / or it has a special structure, and is a multi-metal oxide containing.
