Knothe, Gerhard published the artcileCetane numbers of branched and straight-chain fatty esters determined in an ignition quality tester, Quality Control of 110-34-9, the publication is Fuel (2003), 82(8), 971-975, database is CAplus.
The cetane number, a widely used diesel fuel quality parameter related to the ignition delay time (and combustion quality) of a fuel, has been applied to alternative diesel fuels such as biodiesel and its components. In this work, the cetane numbers of 29 samples of straight-chain and branched C1-C4 esters as well as 2-ethylhexyl esters of various common fatty acids were determined The cetane numbers of these esters are not significantly affected by branching in the alc. moiety. Therefore, branched esters, which improve the cold-flow properties of biodiesel, can be employed without greatly influencing ignition properties compared to the more common Me esters. Unsaturation in the fatty acid chain was again the most significant factor causing lower cetane numbers Cetane numbers were determined in an ignition quality tester (IQT) which is a newly developed, automated rapid method using only small amounts of material. The IQT is as applicable to biodiesel and its components as previous cetane-testing methods.
