简介:氯化钾,AR,99.5%被广泛用作钾补充剂。氯化钾,AR,99.5%是一种容易获得的钾肥[1]。

氯化钾物理化学性质:

密度

1.98 g/mL at 25 °C(lit.)

沸点

1420°C

熔点

770 °C(lit.)

分子式

ClK

分子量

74.551

闪点

1500°C

精确质量

73.932564

外观性状

白色晶体

折射率

n20/D 1.334

储存条件

1.应贮存在通风、干燥的库房内。不可露天堆放,注意防潮。

2.不可与有毒有害物品共贮混运。运输过程中要防雨淋和日晒。

3.装卸时要轻拿轻放,防止包装破裂而受潮。失火时,可用水、沙土、各种灭火器扑救。

稳定性

1.纯品不潮解。有苦咸味。有吸湿性。在水中的溶解度随温度的升高而迅速增加。

2.约1500℃升华。钠和镁的氯化物能降低其在水中的溶解度。15℃饱和水溶液的相对密度为1.172,pH约为7。有刺激性。

3.在空气中稳定。在100g水中的溶解度为34.7g(20℃),56.0g(100℃)。不溶于乙醇。

水溶解性

340 g/L (20 ºC)
