Abstract

Способ очистки уксусного ангидрида путем обработки окислителем. В качестве окислителя используют перекись водорода и процесс ведут в ректификационной колонне в присутствии 1-3 г нитрата аммония на 1 т очищаемого продукта при температуре 100-145°С при атмосферном или пониженном давлении и времени контакта 3-30 минут.Method for purifying acetic anhydride by treatment with an oxidizing agent. Hydrogen peroxide is used as an oxidizing agent and the process is carried out in a rectification column in the presence of 1-3 g of ammonium nitrate per 1 ton of the purified product at a temperature of 100-145 ° C at atmospheric or reduced pressure and a contact time of 3-30 minutes.
