利用氯化亚锡高铁废液制备焦磷酸亚锡

摘要

通过改善复分解反应中的PH与反应温度条件，研制出使用氯化亚锡高铁废液生产焦磷酸亚锡的工艺条件，采用该工艺生产的产品纯度可达98%以上。该工艺操作简单，不仅可以制备焦磷酸亚锡，也可同时处理氯化亚锡生产过程中所产生的废液，是一种节约创效的新工艺。%PH and the reaction temperature by the improvement in the metathesis reaction conditions, process conditions developed using the stannous chloride high-speed rail waste production stannous pyrophosphate, the purity of the product using the technology to produce up to 98%. The process is simple operation, can be prepared not only stannous pyrophosphate, stannous chloride, the liquid waste generated in the production process can be processed simultaneously, the new technology is an economical and create interest.
