Abstract

a. Procédé pour la séparation et la récupération continues de l'isobutène. b. Il se caractérise en ce que le mélange d'hydrocarbures contenant l'isobutène est mis en contact avec de l'eau en présence d'une résine échangeuse de cations, en ce que le tertbutanol contenu dans le mélange réactionnel ainsi obtenu est ensuite déshydraté en présence d'une résine échangeuse de cations à 90-180 degrés C sous une pression de 1,5-15 kg/cm**2 et en ce que l'isobuténe est isolé par distillation. c. Industrie pétrolière.at. Process for the continuous separation and recovery of isobutene. b. It is characterized in that the mixture of hydrocarbons containing isobutene is brought into contact with water in the presence of a cation exchange resin, in that the tertbutanol contained in the reaction mixture thus obtained is then dehydrated in presence of a cation exchange resin at 90-180 degrees C under a pressure of 1.5-15 kg / cm ** 2 and in that the isobutene is isolated by distillation. vs. Oil industry.
