Abstract: A process for separating a fraction containing low and middle boilers from a mixture of low, middle and high boilers, which involves treating the mixture in a column with low-boiler vapor in the bottom, so that the middle-boiling component accumulates in the low-boiler vapor and can be obtained at the temperature level of the low-boiling component.
