Abstract

1,261,564. Cracking dicyclopentadiene. HOOKER CHEMICAL CORP. 7 Oct., 1969 [11 Oct., 1968], No. 49171/69. Heading C5E. Monocyclopentadiene is obtained by cracking dicyclopentadiene by heating at 250-350‹ C. in a hydrocarbon solvent, partially condensing the cracked gaseous mixture by retention for 1-8 seconds in a condenser, and recovering monocyclopentadiene from the remaining gases by distillation. The solvent may be aromatic or paraffinic, and is preferably a paraffinic solvent of the type used in the process of Specification 1,261,565.
