Azide震动或摩擦会容易爆炸
例如倒药时残留在瓶颈磨砂口处
接冷凝管就可能会有危险
学长说秤完azide 先取一些反应溶剂洗瓶颈可避免危险
另外azide与含氯solvent也会反应
http://en.wikipedia.org/wiki/Azide 其中safety的部分
It has been reported that sodium azide and polymer-bound azide reagents react
with dichloromethane and chloroform to form di- and triazidomethane resp.,
which are both unstable in high concentrations in solution. Various
devastating explosions were reported while reaction mixtures were being
concentrated on a rotary evaporator. The hazards of diazidomethane (and
triazidomethane) have been well documented.
已有文献报导sodium azide与接azide的聚合物会与二氯甲烷或氯仿反应分别生成di与
triazidomethane(Me-(N3)2, Me-(N3)3)。
这两种化合物在高浓度溶液中都不稳定。
在回旋浓缩时发生毁灭性爆炸的事件也已有文献报导。

4F:推 tallgeese05:我的也可以转 只是有人知道ClO4-怎样的状况容易炸吗? 02/28 11:14
5F:推 longface:ClO4-是强氧化剂,是否可能氧化N3-导致爆炸? 02/28 12:31
