Cyclopentadiene (C5H8) ruwa ne mara launi, ƙamshi mai ƙamshi. Olefin ne mai matuƙar rashin ƙarfi wanda aka yi shi da polymerized sosai kuma yana iya ƙonewa.
Cyclopentadiene yana da aikace-aikace da yawa a cikin binciken kimiyya. Hakanan za'a iya amfani da shi azaman ɗanyen abu don polymers da rubbers don haɓaka halayensu na zahiri da sinadarai.
Akwai manyan hanyoyi guda biyu don shirye-shiryen cyclopentadiene: ana samar da ɗayan daga fashewar man paraffin, ɗayan kuma an shirya shi ta hanyar isomerization dauki ko halayen hydrogenation na olefins.
Cyclopentadiene yana da rauni sosai kuma yana ƙonewa, kuma ruwa ne mai ƙonewa. A cikin tsarin ajiya da sufuri, ana buƙatar ɗaukar matakan rigakafin gobara da fashewa don guje wa haɗuwa da buɗewar wuta da yanayin zafi. Saka kayan kariya masu dacewa kamar safar hannu, tabarau, da tufafin fashewa yayin amfani da sarrafa cyclopentadiene. A lokaci guda kuma a kula don gujewa cudanya da fata da kuma shakar tururinsa, don kada a haifar da hargitsi da guba. A yayin da yatsa na bazata, yanke tushen ruwan da sauri kuma a tsaftace shi da kayan da suka dace. A cikin samar da masana'antu, hanyoyin aminci masu dacewa da matakan aiki suna buƙatar a bi don tabbatar da amincin aiki.
