N-溴代丁二酰亚胺（NBS）由于存放不完善已经失效变成了黄色,该如何处理?
重结晶后颜色纯白.下面是重结晶方法：
NBS 用10倍煮沸的水溶解,抽滤,抽滤瓶里预先放置冰水混合物,然后冰水洗涤,过滤后常温真空干燥几天.用过之后在瓶里充好氮气存放,不易变质.
N-Bromosuccinimide (30g) was dissolved rapidly in 3OOmL of boiling water and filtered through a fluted filter paper into a flask immersed in an ice bath,and left for 2h.The crystals were filtered,washed thoroughly with cu lOOmL of ice-cold water and drained on a Buchner funnel before drying under vac over P2O5 or CaC12.
再问： 关键我有100Kg的东西要处理啊，不是100g，还有别的办法吗？最好让它变成无毒害的东西然后直接丢掉。
再答： 那还是找厂家回收吧，价格低一点，会有人要的。
