Abstract

There is a great deal of interest in formulating oxygenated diesel fuels that produce low particulate emissions. In this paper, the fourth in a series of papers on the properties of mixtures of diesel fuel with oxygenating additives, we present the volatility, as measured by the advanced distillation curve of diesel fuels with potential fuel additives: 1-propanol, 1-butanol, 1-pentanol, 2-ethoxyethanol, 2-butoxyethanol, butanal, pentanal, methyl butanoate, and ethyl butanoate. As observed in earlier studies of oxygenate additive mixtures, the more volatile additives cause significant early departures from the distillation curves of diesel fuel, while the less volatile additives act more to displace the entire curve. Also, the additive affects the curve shape and temperature profile even after being totally depleted. We also note that oxygenates with higher heat capacities had higher variability among distillation curves. This is probably due to the onset of film boiling in the distillation flask. We present the results for the initial boiling behavior and the distillation curve temperatures, as well as track the oxygenate additives throughout the distillations. These data will aid in determining the suitability of these types of compounds as oxygenate additives.
