Imidazolium-based ionic liquid mixtures with [NO] and [AlCl] anions were used as oxidizing agents for the dissolution of Au, Pd, and Pt metals under mild conditions. The thermodynamic reduction of [NO] to [NO] is catalyzed by [AlCl] anions and coupled with the oxidation process of noble metals. The developed ionic liquid system for dissolving Au can reactivate the Au formed in the deactivation process of the catalyst in vinyl chloride production. This demonstrates the relevance of the here-presented work for technical noble metal recycling.
基于咪唑鎓的离子液体混合物与[NO]和[AlCl]阴离子被用作氧化剂，用于在温和条件下溶解金、钯和铂金属。[AlCl]阴离子催化[NO]到[NO]的热力学还原，并与贵金属的氧化过程耦合。所开发的用于溶解金的离子液体体系可以使氯乙烯生产中催化剂失活过程中形成的金重新活化。这证明了本文所开展工作对于工业贵金属回收的相关性。
