Abstract: Process for the manufacture of lubricating base oils from nitrogen-containing distillate and/or deasphalted oils by catalytic hydrotreatment followed by a dewaxing treatment, which comprises subjecting nitrogen-containing distillates and/or deasphalted oils to solvent extraction and subjecting the raffinate and/or the extract produced to a further treatment to obtain a low-nitrogen fraction and a high-nitrogen fraction and subjecting the low-nitrogen fraction from the extract and/or the high-nitrogen fraction from the raffinate to catalytic hydrotreatment.
