物化性质

外观与性状:
无色晶体或白色粉末
密度:
1.00 g/mL at 20 °C
熔点:
334 °C(lit.)
沸点:
100 °C750 mm Hg
闪点:
400°C
水溶解性:
320 g/L (20 ºC)
存储条件/存储方法:
库房通风,轻装轻卸,与有机物、还原剂、木炭、硫磷易燃物分开存放
稳定性相关:

1.约400 ℃时分解放出氧,并转变成亚硝酸钾,继续加热则生成氧化钾。在空气中不易潮解。为强氧化剂,与有机物接触能引起燃烧爆炸,并放出有刺激性气味的有毒气体。与碳粉或硫黄共热时,能发出强光和燃烧。

2.稳定性[8] 稳定

3.禁配物[9] 强还原剂、强酸、易燃或可燃物、活性金属粉末

4.避免接触的条件[10] 受热、潮湿空气

5.聚合危害[11] 不聚合

6.分解产物[12] 氮氧化物、氧气

其它信息:

1.性状:无色透明斜方或三方晶系颗粒或白色粉末[1]

2.熔点(℃):334[2]

3.沸点(℃):400(分解)[3]

4.相对密度(水=1):2.11[4]

5.溶解性:易溶于水,溶于甘油,不溶于无水乙醇、乙醚。[5]
