Integrated process for producing vinyl acetate from acetic acid via ethylene |
| abstract |
The present invention provides an integrated two-stage economic process for producing vinyl acetate monomer (VAM) from acetic acid in the gas phase. First, acetic acid is hydrogenated either in a single reactor zone or in a dual reactor zone where the intermediate hydrogenation product is either dehydrated and / or cracked to form ethylene. Is selectively hydrogenated over the fluorination catalyst composition to form ethylene. In the subsequent second stage, the ethylene thus formed is reacted with molecular oxygen and acetic acid on a suitable catalyst to form VAM. In one aspect of the invention, ethylene is selectively produced by reaction of acetic acid with hydrogen on a hydrogenation catalyst and subsequent reaction on a dehydration catalyst, which is further mixed with acetic acid and molecular oxygen, React over a supported palladium / gold / potassium catalyst. [Selection figure] None |
