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.
