Abstract:
The present invention relates to a phenylenediamine based antioxidant compound for bio-diesel and a fabrication method of the same. A phenylenediamine based antioxidant is useful as an antioxidant compound for improving the oxidation stability of the bio-diesel by having high activity on antioxidation because the antioxidant supplies hydrogen to a radical and becomes a phenoxy radical which is stabilized by resonance.
