ABSTRACT:
In a process for the continuous fractional distillation of mixtures comprising tetrahydrofuran, γ-butyrolactone and/or 1,4-butanediol to give at least three fractions, the fractionation is carried out in an assembly of distillation columns comprising at least one dividing wall column or at least one assembly of thermally coupled conventional distillation columns.
