摘要：
The content and composition of arenes in dewaxed 200-320 degrees C fraction and the distribution of arenes in close-cut fractions obtained by distillation was studied by UV and H-1 and C-13 NMR spectroscopy. Single- and multistep countercurrent extraction of arenes with acetone-water and acetone-ethylene glycol mixtures and with acetonitrile from the fractions treated to remove linear paraffins was studied with the aim of obtaining an environmentally acceptable component of diesel fuel.
