The invention relates to a process for simultaneously obtaining pure benzene and pure toluene by extractive distillation with N-formylmorpholine and/or other N-substituted morpholines whose substituents contain no more than seven C atoms, as solvents. In this process, a benzene fraction of boiling range between 75 and 85 DEG C and a toluene fraction of boiling range between 99 and 111 DEG C are removed from the starting material by pre-distillation. The benzene fraction is passed into the lower portion and the toluene fraction into the upper portion of the extractive distillation column, which is separated into two portions by a riser plate.
