Descrizione generale
Potassium hydride is a strong base and hydride donor to Lewis acids. It is generally employed in organic reactions like deprotonation, rearrangement, and elimination reactions. It is also used as a reducing agent to reduce hindered boranes and borates to substituted borohydrides.
Applicazioni
Potassium hydride in paraffin can be used as a base in:
- Wittig reaction of various aldehydes with high Z selectivity.
- Williamson ether synthesis to prepare substituted ethers from alcohols.
- Polymerization of ethylene oxide to yield polyethylene glycols.
Proprietà fisiche
Melting point of paraffin used to prepare mixture is ~55-65 °C

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
