Kolbe Electrolysis

2CH3COO → C2H6 + 2CO2 + 2e

ภาพรวม

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.
