ABSTRACT:
A process for purifying a crude isoprene containing polymerization inhibiting materials such as acetylenes and sulfur compounds to produce high purity or polymerization grade isoprene comprising distilling the crude isoprene in the presence of at least one member selected from saturated hydrocarbons containing 6 to 8 carbon atoms, withdrawing the polymerization inhibiting materials as an overhead fraction and obtaining purified isoprene as a bottom fraction.
