  • METHOD FOR PRODUCING VINYL ACETATE
    Publication number: 20140303398
    Abstract: The present invention discloses a method for producing vinyl acetate. Inert gas is introduced into cycling gas to improve the explosion limit of oxygen, enlarge a stable area of a reaction system and improve the oxygen concentration of the reaction system, thus reducing the reaction temperature, prolonging the service life of a catalyst, and improving the selectivity of the vinyl acetate. The inert gas is nitrogen or a mixture of nitrogen and methane. The concentration of the inert gas at the inlet of a reactor is 8 to 30 mol %. The molar concentration of the oxygen at the inlet of the reactor is 10.5 to 12 mol %.
