Method for recycling [(COD)IrCl]2

一种1,5-环辛二烯氯化铱二聚体的回收再生方法

Abstract

本发明公开了一种1,5-环辛二烯氯化铱二聚体[(COD)IrCl]2的回收再生方法:将失活或部分失活的[(COD)IrCl]2于盐酸中转化得到铱氯化物混合物,铱氯化物混合物和1,5-环辛二烯在醇-水体系中反应重新获得活性的[(COD)IrCl]2化合物。本发明公开的1,5-环辛二烯氯化铱二聚体的回收再生方法可以提高贵金属铱的利用率,有效降低生产成本,本方法操作过程简单,回收率高,条件温和。本发明适用于贵金属铱催化剂回收。
The invention discloses a method for recycling [(COD)IrCl]2. By the adoption of the method for recycling [(COD)IrCl]2, inactive [(COD)IrCl]2 or partially inactive [(COD)IrCl]2 is converted in hydrochloric acid, so that an iridium chloride mixture is obtained, the iridium chloride mixture and 1,5-cyclooctadiene react in an alcohol-water system, so that an active [(COD)IrCl]2 compound is obtained again. By the adoption of the method for recycling [(COD)IrCl]2, the utilization rate of the noble metal iridium can be increased, and the production cost can be effectively reduced; in addition, the operation process is simple, the recycling rate is high, and conditions are gentle. The method for recycling [(COD)IrCl]2 is suitable for recycling of iridium catalysis, wherein iridium is noble metal.
