EXTRACTION ENNOBLEMENT OF DIESEL DISTILLATE AND ITS CLOSE-CUT FRACTIONS

The results of the studies, carried out on the initial diesel distillates, and also raffinates and extracts, ob-tained by their extractive purification in the presence of ionic liquid on the basis of N-methylpyrrolidone and acetic acid as a selective solvent are presented. Hydrocarbon compositions of the raffinate and ex-tract, obtained by selective purification of diesel distillate and its close-cut fractions has been deter-mined by IR spectral analysis. Advantages and prospects of used ionic liquid have been presented in comparison with N-methylpyrrolidone in the processes of selective purification of diesel distillate
