Beschreibung

Anwendung

Potassium ethoxide can be used:

• As a catalyst for transesterification reactions for the synthesis of biodiesel.
• To synthesize nitrogen doped carbon nano-sheets to be used as an anode in sodium ion batteries.
• To promote the arylation reaction of unactivated arenes to synthesize biaryl compounds.
• As a precursor for the synthesis of thin films of (Na_0.5K_0.5)NbO₃ (NKN) and K₃Li₂Nb₅O₁₅ (KLN).
• For ethoxylation of p-chloronitrobenzene in the presence of phase transfer catalysts.
