摘要:
A process is disclosed for separating a fraction which contains low and medium boiling substances from a mixture of low, medium and high boiling substances. The mixture is treated at the bottom of the distillation column with low boiling vapour, enriching the low boiling vapour with medium boiling substances which can then be extracted at the temperature level of the low boiling substance.
