  • Methods for Producing a Vinyl Acetate Composition Having a Low Impurity Content
    Publication number: 20120108842
    Abstract: In one embodiment, the invention is to a method for producing a vinyl acetate composition. The method comprises the step of contacting acetic acid, oxygen, and ethylene under conditions effective to form a crude vinyl acetate composition comprising vinyl acetate, acetic acid, residual oxygen, and water. The method further comprises the step of contacting the crude vinyl acetate composition or a derivative thereof with at least one scavenger to form a treated crude vinyl acetate composition.

  • INTEGRATED PROCESS FOR PRODUCING ALCOHOLS FROM A MIXED ACID FEED
    Publication number: 20120036769
    Abstract: Processes for producing alcohols such as ethanol and propanol from a mixed acid feedstock in an integrated process. In one embodiment, the process comprises the step of carbonylating methanol in the presence of a carbonylation catalyst to form a mixed acid feedstock comprising acetic acid and one or more higher acids, preferably comprising propionic acid. The mixed acid feed is hydrogenated in the presence of a hydrogenation catalyst to form a crude alcohol product comprising ethanol and one or more higher alcohols, preferably including propanol.

  • Liquid Esterification For The Production Of Alcohols
    Publication number: 20120010437
    Abstract: Purifying and/or recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid. Separation and purification processes of crude ethanol mixture are employed to allow recovery of ethanol and remove impurities. In addition, the process involves returning acetaldehyde separated from the crude ethanol product to the reactor.

  • Reduced Energy Alcohol Separation Process
    Publication number: 20120010438
    Abstract: Recovery of alcohols, in particular ethanol, from a crude ethanol product obtained from the hydrogenation of acetic acid using a reduced energy process. The crude ethanol product may be fed to a distillation column in which a substantial portion of the water is removed with the acetic acid in the residue. The ethanol product is obtained from the distillate.
