Abstract:
1. A method for improving low-temperature properties of a biodiesel fuel, said method comprising the steps of: a) providing a first biodiesel fuel comprising unsaturated ester molecules; b) extracting at least some of the unsaturated ester molecules from the first biodiesel fuel so as to provide an extract; c) treating the extract with an oxidizing species so to convert at least some of the unsaturated ester molecules contained therein into epoxy-ester species and provide for an epoxy-ester-containing intermediate; d) reacting at least some of the epoxy-ester species in the epoxy-ester-containing intermediate with one or more reactants to produce a functionalized ester composition comprising functionalized ester species; and e) adding the functionalized ester composition to a second biodiesel fuel so as to provide for an enhanced biodiesel fuel.
