Способ выделения ароматических углеводородов из депарафинированной фракции 200-320oС путем жидкостной экстракции, отличающийся тем, что, с целью повышения селективности процесса, повышения степени извлечения и концентрации ароматических углеводородов в экстракте, увеличения выхода рафината и снижения содержания в нем аренов, в качестве экстрагента используют метилцеллозольв, содержащий 0,3-10,0 мас.% воды (предпочтительно 5 мас.% воды), и в качестве второго, не смешивающегося с экстрагентом растворителя - н-пентан.The method of separation of aromatic hydrocarbons from the dewaxed fraction 200-320 o With liquid extraction, characterized in that, in order to increase the selectivity of the process, increase the degree of extraction and concentration of aromatic hydrocarbons in the extract, increase the yield of raffinate and reduce the content of arenes in it, as an extractant use methyl cellosolve containing 0.3-10.0 wt.% water (preferably 5 wt.% water), and n-pentane, which is not miscible with the extractant, is used.
