PROCESS FOR SEPARATING ISOPRENE

摘要

Isoprene is sepd. from the raw mixt. contg. isoprene and one min. of addn.-hydrocarbon(selected from isobutylene, isopentane, pentene-1 gp.). Raw mixt. absorbed on activated carbon or molecules of carbon for selective a obsorbed of isoprene except addn.hydrocarbon. Non- absorbed raw eliminated by absorbent. Absorption and desorption of isoprene for high purity performed in the liq. phase maintenance temp.(20-250≦̸C) and pressure sufficiently. Desorbent are olefins hydrocarbon contg. up 6 carbon atom e.g. hexene-1.
