Method of removing iodine compounds from crude acetic anhydride or mixture of crude acetic anhydride and crude acetic acid |
| abstract |
A process by which iodine compounds contained in crude acetic anhydride or a mixture of crude acetic anhydride and crude acetic acid can be converted into methyl iodide having a low boiling point and separable by distillation and efficiently removed by the combination of the conversion step with the heat treatment step and distillation step, which comprise the steps of heat-treating the crude acetic anhydride or the mixture of crude acetic anhydride and crude acetic acid in the presence of methanol and/or methyl acetate in a treatment tank and distilling the heat-treated crude acetic anhydride or the heat-treated mixture of crude acetic anhydride and crude acetic acid, in the presence of an alkali metal salt and/or an alkaline earth metal salt if necessary. |
