    Abstract: A process for treating a recycling stream from a plant for the production of polyarylene ether sulfones comprising 60 to 90% water, 10 to 40% N-alkyl-2-pyrrolidone, up to 5000 ppm by weight of the alkylsuccinimide corresponding to the N-alkyl-2-pyrrolidone, up to 1000 ppm by weight of other substances with higher boiling point than N-alkyl-2-pyrrolidone, giving N-alkyl-2-pyrrolidone which can be recycled via a distillation column , preceded by preliminary purification in evaporator stage(s), giving vapor stream(s) which are introduced as feed streams into the distillation column, the bottom stream from the last evaporator stage being discharged and the bottom stream from the distillation column being recycled into the last evaporator stage, and the vapor stream from the last evaporator stage being introduced fully or partly into an additional column from which a top stream is introduced into the distillation column and a bottom stream is discharged.
