The preparation and characterization of a novel biodiesel named curcas oil diethylene glycol ether ester
摘要
Abstract
In this paper, 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 were determined by orthogonal test. The molar ratio of methanol to oil was 6:1, catalyst amount was 1.2% of feedstock quality, reaction temperature was 65 ℃, reaction time was 30 minutes. FT-IR and IH-NMR were used to analysis and validate the molecular structure of curcas oil diethylene glycol ether esters. The physical and chemical properties of GDGEE and its blends with 0# diesel oil were tested by the national standard method. The physical and chemical properties include oil soluble, smoke point, kinematic viscosity, freezing point and closed flash point. At last, smoke emission were test among GDGEE, curcas oil methyl and 0# diesel in the same diesel engine. The results confirm that GDGEE owns the higher oxygen content, good physochemical and emission properties, which can be used as diesel fuel additives or also be used instead of diesel fuel alone. A certain application value of it was easy to know.关键词
