Abstract

Le butène-1 est récupéré à partir d'un flux d'hydrocarbures en C4, en le soumettant à une éthérification avec un alcool aliphatique en vue l'isobutène qui est transformé en éther alkyl-tertio-butylique; séparation de l'éther tertiaire ainsi formé; séparation de l'isobutane par distillation; séparation du butène-1 par distillation; hydrogénation sélective du butadiène et des dérivés acétyléniques; distillation du flux hydrogéné avec séparation du butène-1 de qualité appropriée pour la polymérisation.Butene-1 is recovered from a stream of C4 hydrocarbons, by subjecting it to etherification with an aliphatic alcohol with a view to isobutene which is converted into alkyl tertiary butyl ether; separation of the tertiary ether thus formed; separation of isobutane by distillation; separation of butene-1 by distillation; selective hydrogenation of butadiene and acetylenic derivatives; distillation of the hydrogenated stream with separation of butene-1 of a quality suitable for polymerization.
