SUMMARY:

Electrochemical processes are promising alternative routes to promote cleaner, safer, and more sustainable redox transformations. The decarboxylative upgrading of biogenic acids via (non-)Kolbe electrolysis has demonstrated a high potential to produce valuable compounds for the chemical and fuel industries. Notably, bio-derived hydrocarbons and oxygenates have shown adequate properties that enable their use as fuel additives associated with reduced levels of emissions. Therefore, the research reported herein aimed to develop an electrocatalytic method to decarboxylate C12:C18:1 fatty acids which are predominant in the composition of liquid biofuel feedstocks. The reaction products were analyzed by CG/MS, FTIR, and TG/DTG techniques. In the absence of metal-based catalysts, additives, or redox reagents, the electrochemical system enabled the quantitative conversion (97-100%) of pure fatty acids, as well as mixtures, including the one produced through Licuri oil hydrolysis, to afford mixtures composed by 19-36% of C11-C17 olefins at room temperature and pressure, employing graphite electrodes. The electrodecarboxylative protocol demonstrated the potential to serve as an alternative to hydrogen-based thermocatalytic reactions to produce renewable hydrocarbons under exceptionally mild reaction conditions.
