Abstract
A process for the distillative separation of ethylbenzene from a mixture comprising ethylbenzene and at least one other C8 aromatic compound, comprising introducing a feed stream comprising said mixture into a first distillation column, introducing a first stream comprising a heavy solvent above the feed stream into the first distillation column, introducing an aqueous stream below the feed stream into the first distillation column.

A process for the distillative separation of ethylbenzene from a mixture comprising ethylbenzene and at least one other C8 aromatic compound selected from the group consisting of p-xylene, m-xylene, o-xylene, and mixtures thereof, the process comprising:
- a) introducing a feed stream comprising said mixture into a first distillation column,
- b) introducing a first stream comprising a heavy solvent above the feed stream into the first distillation column,
- c) introducing an aqueous stream below the feed stream into the first distillation column.

A process for the distillative separation of ethylbenzene from a mixture comprising ethylbenzene and at least one other Cg aromatic compound, the process comprising:
- a) introducing a feed stream comprising said mixture into a first distillation column;
- b) introducing a first stream comprising a heavy solvent above the feed stream into the first distillation column;
- and
- c) introducing an aqueous stream below the feed stream into the first distillation column, the aqueous stream having a mass feed from 5 wt % to 25 wt % based on a mass feed of the heavy solvent.
