Kolbe Electrolysis

2CH₃COO⁻ → C₂H₆ + 2CO₂ + 2e⁻

Ikhtisar

Kolbe electrolysis oxidizes carboxylate anions at the anode, decarboxylating them to form alkyl radicals that dimerize. Two acetate ions lose CO₂ to form two methyl radicals that couple to produce ethane. This is one of the oldest electroorganic reactions, discovered in 1849.
