Abstract

A process for removing acetone from a mixture of acetone / methyl acetate / methyl iodide, consisting of a water extraction distillation that is added to the distillation area above the processing site. To put this mixture And put acetic acid at or above the point of insertion of this mixture Among the methods that should be chosen are the mixtures for extraction at the beginning. With an extract in water To get rid of as much methyl iodide as possible Especially This method can be applied to Eliminate acetone by-products in the carbonation process. For production Acetate anhydride
