Transesterified milkweed (asclepias) seed oil as an alternative diesel fuel [abstract]. 97th American Oil Chemists' Society Annual Meeting and Expo. p. 67. Interpretive Summary: Technical Abstract: The methyl and ethyl esters of Milkweed (Asclepias) seed oil were prepared and compared to soya esters in laboratory tests to determine biodiesel fuel performance properties. The pour points of the methyl and ethyl milkweed esters measured -6 deg C and -10 deg C, respectively, which is consistent with the high unsaturation characteristic of milkweed seed oil. The oxidative stabilities measured at 100 deg C were between 1.4 and 1.8 hr for all samples tested. The kinematic viscosities determined at 40A deg C by ASTM D 445 were 4.6 mm2/s for milkweed methyl esters and 4.2 mm2/s for methyl soyate. Lubricity values determined by ASTM D 6079 at 60A deg C were comparable to the corresponding soya esters with average ball wear scar values of 146 um for milkweed methyl esters and 200 um for milkweed ethyl esters. |
