FIELD: chemistry.SUBSTANCE: invention relates to a method of producing naphthenic process oil, having ratio of content of carbon atoms of aromatic hydrocarbons Cto content of napthenic carbon atoms Cto content of carbon atoms of paraffin hydrocarbons C, determined in accordance with ASTM D 2140, of 0-30 wt % to 20-65 wt % to 20-55 wt %, and content of polycyclic aromatic compounds, in accordance with IP 346, of less than 3 wt %, characterised by that a process oil educt having content of polycyclic aromatic compounds, determined in accordance with IP 346, of at least 3 wt %, and content of naphthenic carbon atoms C?25 wt %, is hydrogenated with hydrogen using a metal catalyst at temperature of 200-400°C and pressure of 80-250 bar. The invention also relates to use of naphthenic process oil.EFFECT: obtaining high-quality naphthenic process oil with high content of naphthenic hydrocarbon compounds.10 cl, 3 dwg, 4 tbl, 2 ex |
