The invention relates to a method for the distillation of the separation of ethylbenzene from a mixture that contains ethylbenzene and at least one other aromatic compound. The method includes: a) introducing a feed stream that contains the mixture into the first distillation column, b) introducing the first stream that contains a heavy solvent, above the feed stream into the first distillation column, c) introducing the aqueous stream below the feed stream into the first distillation column wherein the aqueous stream contains water and at least one light solvent selected from Cl-, S-, N-, or O-containing compound, and mixtures thereof. The invention also relates to the use of an aqueous stream comprising a light solvent. The use of the present invention allows to separate ethylbenzene more efficiently. 2 n. and 13 hp f-ly, 1 ill., 1 tab., 1 ave. |
