Cyclopentadiene (C5H8) bụ mmiri na-esi ísì ụtọ na-enweghị agba. Ọ bụ olefin na-adịghị akwụsi ike nke ukwuu bụ nke polymerized nke ukwuu ma na-ere ọkụ.

Cyclopentadiene nwere ọtụtụ ngwa na nyocha kemịkalụ. Enwere ike iji ya dị ka ihe eji eme ihe maka polymers na rubbers iji meziwanye ihe anụ ahụ na kemịkal ha.

Enwere ụzọ abụọ bụ isi maka nkwadebe nke cyclopentadiene: otu a na-emepụta site na mgbawa nke mmanụ paraffin, nke ọzọ na-akwado ya site na mmeghachi omume isomerization ma ọ bụ mmeghachi omume hydrogenation nke olefins.

Cyclopentadiene na-agbanwe nke ukwuu ma na-ere ọkụ, ọ bụkwa mmiri mmiri na-ere ọkụ. N'ime usoro nchekwa na njem, ọ dị mkpa ka e mee ihe mgbochi ọkụ na mgbawa iji zere kọntaktị na ọkụ na-emeghe na okpomọkụ dị elu.
