Process for converting biosourced triglycerides into a single-phase composition containing fatty acid ester and related uses as biofuel or lubricant

Abstract

The present techniques relate to facilitating conversion of biosourced triglycerides into fatty acid esters by combining the biosourced triglycerides with a carbonate ester in presence of an alcohol, under catalytic transesterification conditions. A reaction mixture can be heated to a reaction temperature to operate a transesterification of the biosourced triglyceride with the carbonate ester under catalysis of the alcohol thereby forming a single-phase composition comprising the fatty acid esters. The reaction mixture can have a molar ratio of the biosourced triglyceride over the carbonate ester between 1:0.1 and 1:20. Compositions comprising the produced single-phase composition, and optionally an additive, can be used as diesel, jet fuel or lubricant.
