Parallel to the liquid-phase process, ethylene acetoxylation was also developed as a gas-phase process. There is a distinctive difference between the two processes: in the liquid phase, in the presence of palladium salts and redox systems, both vinyl acetate and acetaldehyde are formed, while in the gas-phase process using palladium or chlorine-free palladium salts, vinyl acetate is formed almost exclusively. Furthermore, there are no noticeable corrosion problems in the gas-phase process. The most suitable construction material is stainless steel
