Process for the production of vinyl acetate in a fixed bed reactor comprising a catalyst bed, where it is provided: (a) a tube, coupled to the fixed bed reactor, said tube having an elbow and a flow correction device downstream of the elbow, (b) a nozzle that is installed at one end of a support arm, said nozzle being located in the tube so that the nozzle is located downstream of the elbow and downstream of the flow correction device, and wherein the support arm extends into the tube in a direction substantially parallel to the direction of the tube downstream of the elbow, said process comprising the steps of: (i) feeding a reactant stream of the process comprising acetic acid, ethylene and oxygen into the reactor along the tube, (ii) feeding a catalyst promoting fluid to the process reactant stream through the nozzle to deposit the promoter on the catalyst bed and (iii) react ethylene, acetic acid and oxygen-containing gas in the reactor to produce vinyl acetate. |
