  • Recovery of Acetic Acid from Heavy Ends in Vinyl Acetate Synthesis Process
    Publication number: 20120149939
    Abstract: Recovery of acid, and in particular acetic acid, in a vinyl acetate production process. Vinyl acetate production produces heavy ends that comprise acetate containing compounds, such as monomers and polymers. Acid preferably is recovered by hydrolyzing the heavy ends and separating the resulting hydrolyzed stream to recover acid formed from the from acetate containing compounds.
