摘要： A method for separating a catalyst from a solution containing same by membrane electrodialysis is disclosed. Specifically, the separation of a catalyst used in a homogeneous-phase molecular oxidation reaction is disclosed. According to the method for separating a homogeneous catalyst dissolved in a medium that also contains at least one aliphatic diacid, the catalyst contains cobalt and separation is achieved by membrane electrodialysis.

摘要： The present invention relates to an electrochemical process for the preparation of compounds which can be used as catalysts. The disclosed compounds comprise more specifically a transition metal with an oxidation degree of 0 or 1 associated to at least one monodentate or bidentate hydrosoluble phosphine. The process for the electrochemical synthesis of catalysts comprises the treatment by electrolysis of an aqueous solution containing at least a compound of a transition metal and a monodentate or bidentate hydrosoluble phosphine placed within the cathode compartment of an electrolysis cell of an electrolyser.
