Application

Potassium ethoxide can be used:
  • As a catalyst for transesterification reactions for the synthesis of biodiesel.[1][2]
  • To synthesize nitrogen doped carbon nano-sheets to be used as an anode in sodium ion batteries.[3]
  • To promote the arylation reaction of unactivated arenes to synthesize biaryl compounds.[4]
  • As a precursor for the synthesis of thin films of (Na0.5K0.5)NbO3 (NKN)[5] and K3Li2Nb5O15 (KLN).[6]
  • For ethoxylation of p-chloronitrobenzene in the presence of phase transfer catalysts.[7]

The rapid development of modern electrical equipment toward miniaturization and high power puts forward stringent requirements to the mechanical reliability, dielectric property, and heat resistance of electrical insulating materials. Simultaneous integration of all these properties for mica-based materials remains unresolved.
