  • Process and apparatus for preparing vinyl acetate monomer
    Patent number: 8765995
    Abstract: The invention provides a process for preparing vinyl acetate monomer (VAM) by reacting ethylene with acetic acid and oxygen in a tube bundle reactor in a heterogeneously catalysed, continuous gas phase process, characterized in that a high-performance catalyst with a space-time yield of more than 700 g of VAM/l of catalyst×hour is used for catalysis, and in that the tube bundle reactor comprises tubes with a ratio of inner surface area to volume of ?130 m?1.
    Type: Grant
