Methods for producing a vinyl acetate composition having a low impurity content

摘要

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.
