A process for the production of vinyl acetate (VA) by reaction in the vapor phase of ethylene, oxygen and acetic acid as reactants, comprising passing a t a temperature sufficient to initiate the reaction, a feed gas comprising sai d reactants and continuously or intermittently containing liquid acetic acid and/or non-volatile components, through a filter and distribution bed of ine rt material having throughout its volume substantial intercommunicating open spaces among the solid portions, and thence through a plurality of tubes eac h containing a bed of catalyst for the reaction, and withdrawing a product gas comprising VA. The filter and distribution bed acts to filter out the liquid acetic acid and/or non-volatile components and distribute more evenly the fe ed gas into the tubes.
