Tertiary fatty amides as diesel fuel substitutes

This paper presents experimental results regarding the impact of adding dif ferent tertiary amides of fatty acids to mineral diesel fuel; an assessment of the behaviour of these compounds as possible diesel fuel extenders is a lso included. Measurements of cetane number, cold flow properties (cloud po int, pour point and CFPP), density, kinematic viscosity, flash point and di stillation temperatures are reported, while initial experiments concerning the effects on particulate emissions are also described. Most of the examin ed tertiary fatty amides esters have very good performance and they can be easily prepared from fatty acids (biomass). Such compounds or their blends could be used as mineral diesel fuel or even fatty acid methylesters (FAME, biodiesel) substitutes or extenders. Copyright (C) 2000 John Wiley & Sons, Ltd.
