General description
氢化钾是强碱和路易斯(Lewis)酸的氢化物供体。通常用于去质子化、重排和消除反应等有机反应。也作为还原剂,将受阻硼烷和硼酸盐还原为取代的硼氢化物。
用于制备混合物的石蜡的熔点为 ~55-65℃
Application
石蜡中的氢化钾作为碱,可用于:
- 各种醛的Wittig反应, Z 选择性高。
- Williamson醚合成反应,从醇中制备取代醚。
- 环氧乙烷聚合,产出聚乙二醇。

Hyperkalemia (serum potassium level, >5.0 mmol per liter) is associated with increased mortality among patients with heart failure, chronic kidney disease, or diabetes. We investigated whether sodium zirconium cyclosilicate (ZS-9), a novel selective cation exchanger, could lower serum potassium levels
