Abstract
L'invention concerne un procédé de purification d'un isoprène brut renfermant des matières inhibitrices de polymérisation telles que les acétylènes et les composés du soufre pour obtenir un isoprène de grande pureté pouvant être soumis à une polymérisation. Ledit procédé consiste à distiller l'isoprène brut en présence d'au moins un hydrocarbure saturé contenant de 6 à 8 atomes de carbone, à extraire les matières inhibitrices de polymérisation comme fraction de tête et à obtenir l'isoprene purifié comme fraction de queue. Application à la production de polyisoprène.
