The search for sustainable energy sources drives research in biomass conversion. This study investigates the electrochemical decarboxylation of fatty acids from coconut oil through the Non-Kolbe reaction, evaluating solvents, electrolytes, and applied voltage. Methanol achieved 100% conversion of substrate to product, while water and nonpolar solvents exhibited low reactivity. Inorganic bases like KOH, NaOH, and NaHCO3 were more effective than organic bases. High potentials (>10 V) favored oxygenated products, whereas moderate potentials (8–10 V) enhanced the production of linear α-olefins, such as 1-undecene and 1-tridecene. Results demonstrate that the electrosynthesis of fuel additives from fatty acids can offer a sustainable alternative to conventional thermochemical processes. The selective control of products via voltage and electrolyte/solvent choice presents a promising route for efficient and sustainable fuel additive production. This method requires lower energy input than conventional thermochemical routes, providing a more energy-efficient pathway for biomass valorization.
