Reactor and method for synthesising vinyl acetate in the gaseous phase

摘要

Synthesis reactor (I) for preparing vinyl acetate monomer by catalytically reacting gaseous ethylene, acetic acid and oxygen or oxygen containing gas, is a barrier reactor. (I) comprises several reaction chambers in which the catalytic synthesis takes place, where the free conduit in each reaction chamber has dimension less than 2000 mu m and the wall of the chambers is coated with catalysts and is indirectly cooled. An independent claim is also included for a catalyst used in (I) comprising a palladium content of 0.5-10 (preferably 0.8-5) wt.%.
