Abstract
Procedure for the separation of a high purity vinyl aromatic hydrocarbon from hydrocarbon mixtures that contain it, particularly for the separation of styrene from hydrocarbon mixtures that contain it, by extractive distillation in the presence of one or more high boiling point polar solvents, characterized in that the extractive distillation is carried out in the presence of at least one polar solvent with a high boiling point that has added a quantity of water that varies between 1% and 30% by weight, preferably between 5% and 20 %.
