METHOD FOR PRODUCING VINYL ACETATE

The present invention relates to a method for producing vinyl acetate, comprising a vinyl acetate synthesis process, a vinyl acetate refining process and a separation process of vinyl acetate and ethyl acetate, including an acetic acid evaporator, an oxygen mixer, a vinyl acetate synthesis reactor, a first gas separating tower, a second gas separating tower, a recovered gas compressor, a water washing tower, an absorption tower and a desorption tower, a recycling gas compressor; the vinyl acetate refining process comprising an acetic acid tower, a crude VAC tower, and a fine VAC tower, a rectifying tower, an ethyl acetate tower, a water phase receiving tank, an extracting and rectifying tower and an ethyl acetate phase separator. The separation process adopts the acetic acid as the extractant, the content of the vinyl acetate in the stream from which the ethyl acetate impurities are removed is reduced from 90% or above to below 5%, the adopted extractant is the acetic acid contained originally in the feed stream, and the operating cost of the device is greatly reduced.
