摘要：
Jet fuel containing less than 10 wt% arenes and aromatic petroleum solvents of the Nefras AR-120/200 type was prepared by combination of arene extraction from the hydrorefined kerosene fraction with the acetonitrile-pentane system, followed by concentration of arenes in the course of acetonitrile regeneration from the extract phase, based on the formation of azeotropes of acetonitrile with saturated C-9-C-10 hydrocarbons.
