Technical Abstract: Fatty acid methyl esters were prepared and evaluated as potential biodiesel fuels from several alternative oilseed feedstocks, which included camelina (Camelina sativa L.), coriander (Coriandrum sativum L.), field mustard (Brassica juncea L.), field pennycress (Thlaspi arvense L.), and meadowfoam (Limnanthes alba L.) oils. Coriander and meadowfoam oil methyl esters were enriched in the unusual fatty esters methyl petroselinate (6Z-octadecenoate) and methyl 5Z-eicosenoate, respectively, whereas field mustard and field pennycress primarily consisted of methyl erucate (13Z-docosenoate). Camelina was comprised primarily of methyl linolenate (9Z,12Z,15Z-octadecatrienoate) and methyl linoleate (9Z,12Z-octadecadienoate). Using standard methods, fuel properties measured included oxidative stability, low temperature operability, kinematic viscosity, cetane number, sulfur and phosphorous content, acid value, free and total glycerol content, iodine value, heat of combustion, lubricity, and Gardner color. Coriander and especially meadowfoam oil methyl esters exhibited excellent oxidative stability, as indicated by induction periods (EN 14112, 110oC) of 14.6 and 41.5 h, respectively. Lastly, a comparison to biodiesel fuel standards, such as ASTM D6751 and EN 14214, was also made.
