<p>A process for removing acetone from a methyl acetate, methyl iodide and acetone mixture includes the step of removing a side stream from the distillation zone rich in acetone. In a preferred embodiment the methyl acetate, methyl iodide and acetone mixture is contacted with water before or concurrently with fractional distillation. The process is particularly applicable to removing acetone by-product in a carbonylation process for the production of acetic anhydride.</p> |
