Process for separating isoprene
 A process for separating isoprene from isobutylene, isopentane, and pentene-1. The process uses an adsorbent comprising activated carbon or molecular sieve carbon to selectively adsorb isoprene from the other hydrocarbons. High purity isoprene is recovered by desorption using desorbent materials which include olefinic hydrocarbons. The process is particularly suited for a simulated moving bed apparatus.
