Abstract

1308537 Alicyclic conjugated dienes ESSO RESEARCH & ENG CO 5 June 1970 27313/70 Heading C5E Alicyclic conjugated diene dimers are separated from admixture with hydrocarbon impurities capable of forming polymers and tars, by contacting the feed, initially at ambient temperature, with superheated steam in a flash zone 80 as to vaporise the dimers but not the polymers and tars, and then removing polymers and tars from the flash zone, the vaporized feed being dedimerized in a cracking zone to give alicyclic conjugated dienes. The feed may be a steam cracked naphtha containing dimers of cyclopentadienes.
