Application
General description
Melting point of paraffin used to prepare mixture is ~55-65 °C
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.[4]
