In the research, aminoethyl imidazolines of cottonseed oil fatty acids with diethylenetriamine
have been synthesized using the ultrasonic device creating the effect of cavitation. The yield of
imidazolines was 90% - 95%. The influence of the synthesized imidazolines on lubricity quality of
low sulfur diesel fuels having low lubricating quality was studied. The results showed that at concentrations
200 - 250 ppm the synthesized imidazolines can be applied as additives enhancing lubricity
quality of diesel fuels.
