Title:
鉄を他の金属イオンから分離する方法、並びにアルコール及びケトンを酸化してカルボン酸にする反応において触媒を循環させる方法
Document Type and Number:
Japanese Patent JP4401611
Kind Code:
B2
Abstract:
A process is described for recycling catalysts in the reaction for the oxidation of alcohols and/or ketones to carboxylic acids and more particularly the oxidation of cyclic alcohols and/or cyclic ketones to dicarboxylic acids, such as the oxidation of cyclohexanol and/or cyclohexanone to adipic acid. This process involves treating the solution comprising the oxidation catalyst, before it is recycled, with an ion-exchange resin which makes it possible to selectively separate the iron from the other metal elements, in particular from copper and from vanadium.
