The Preparation and Characterization of a Novel Biodiesel Named Curcas Oil Diethylene Glycol Ether Ester

Article Preview

Abstract:

A novel biodiesel named curcas oil diethylene glycol ether esters (GDGEE) with higher oxygen content was prepared by refined curcas oil, methanol and ethylene glycol monomethyl ether as the reaction and KOH as catalyst. The optimum synthesis conditions was determine by orthogonal test, that molar ratio of methanol to oil was 6:1, catalyst amount was 1.2% of feed oil, reaction temperature was 65°C, reaction time was 30min. Both FT-IR and 1H-NMR were used to analysis and validate the molecular structure of GDGEE after preparation. The Physicochemical properties including oil-soluble, smoke point, kinematic viscosity, pour point, copper corrosion and closed cup flash point, were all tested by the national standard method for GDGEE and its blends with 0# diesel oil. The results confirm that GDGEE owns good physicochemical properties which can be used as diesel fuel additives or be used instead of diesel fuel alone, so a certain application value of it can easy be know accepted.
