Abstract
Isoprene is obtained by pyrolysing hexenes, particularly 2-methylpentene-2, obtained by isomerizing a hexene, which may be a propylene dimer, in the presence of a lamellar complex of carbon and an alkali metal as described in Specification 934,449. The pyrolysis is effected at 600 DEG -1000 DEG C. for 0,001-1 second usually in the presence of steam in a mol. ratio to hexenes of up to 10:1. Specifications 840,028 and 841,351 also are referred to.
