| 摘要 |
The invention relates to a process for producing vinyl acetate in a continuous gas-phase process with heterogeneous catalysis by reaction of ethylene with acetic acid and oxygen and then work-up of the product gas stream, where polymerization of vinyl acetate during work-up of the product gas mixture is inhibited by adding, as inhibitors, one or more N-oxyl compounds which contain at least one N-oxyl radical group -N-O", characterized in that the N-oxyl compound is added in the form of an aqueous solution of strength from 50 to 85 % by weight. |
