Methyl and ethyl esters were prepared from camelina [Camelina sativa (L.) Crantz]
oil by homogenous base-catalyzed transesterification for evaluation as biodiesel fuels.
Camelina oil contained high percentages of linolenic (32.6 wt.%), linoleic (19.6 wt.%),
and oleic (18.6 wt.%) acids. Consequently, camelina oil methyl and ethyl esters (CSME
and CSEE) exhibited poor oxidative stabilities and high iodine values versus methyl
esters prepared from canola, palm, and soybean oils (CME, PME, and SME). Other fuel
properties of CSME and CSEE were similar to CME, PME, and SME, such as low temperature
operability, acid value, cetane number, kinematic viscosity, lubricity, sulfur and
phosphorous contents, as well as surface tension. As blend components in ultra low-sulfur
diesel fuel, CSME and CSEE were essentially indistinguishable from SME and soybean
oil ethyl ester blends with regard to low temperature operability, kinematic viscosity,
lubricity, and surface tension.
