| titleOfInvention | Process for the cracking of dicyclopentadiene to monocyclopentadiene |
| abstract | Dicyclopentadiene is craked to form cyclopentadiene by (a) heating the dicyclopentadiene in a hydrocarbon solvent at 250-350 degrees C., (b) partly condensing the cracked gaseous mixture leaving the cracking chamber by retaining this gaseous mixture in a condenser for 1-8 secs., and (c) recovering practically pure cyclopentadiene by distillation. Cracking is carried out at 280-320 degrees C., and the retention time in the condenser is 6.6 secs. Recovery of the cyclopentadiene is effected by fractional distillation. The hydrocarbon solvent is a paraffin with a boiling range of 250-350 degrees C., and 80% of the solvent distils at 20 degrees C. to 10 degrees C. higher than the initial b.pt. according to ASTM test D 86-61. The process may be carried out continuously. The gaseous mixt. is partly condensed at a temp. of 45 degrees C. to 100 degrees C., the paraffin being returned to the cracking chamber, and a practically pure cyclopentadiene being recovered by fractional distillation. |
