Hordhac

Cyclopentadiene (C5H8) waa dareere aan midab lahayn, ur xun. Waa olefin aad u deggan oo si heer sare ah loo sameeyay oo dabci kara.

Cyclopentadiene waxay leedahay codsiyo ballaaran oo kala duwan oo ku saabsan cilmi-baarista kiimikada. Waxa kale oo loo isticmaali karaa walxo cayriin ah oo loogu talagalay polymers iyo caagadaha si loo hagaajiyo hantidooda jireed iyo kiimiko.

Waxaa jira laba hab oo waaweyn oo loogu talagalay diyaarinta cyclopentadiene: mid waxaa laga soo saaraa dildilaaca saliidda paraffin, kan kalena waxaa lagu diyaariyaa falcelinta isomerization ama falcelinta hydrogenation ee olefins.

Cyclopentadiene waa mid aad u kacsan oo guban karta, waana dareere guban kara. Inta lagu jiro habka kaydinta iyo gaadiidka, waxaa loo baahan yahay in la qaado tallaabooyinka ka hortagga dabka iyo qaraxa si looga fogaado in lala xiriiro olol furan iyo heerkul sare. Xidho qalabka ilaalinta ku haboon sida galoofyada, muraayadaha indhaha, iyo dharka qaraxa markaad isticmaalayso oo aad la tacaalayso cyclopentadiene. Isla markaana waa in laga digtoonaado in maqaarka la taabto oo la neefsado uumiga, si aysan u keenin xanaaq iyo sun. Haddii ay dhacdo daadad shil ah, si degdeg ah u jar isha qulqulka oo ku nadiifi walxaha nuugista habboon. Wax-soo-saarka warshadaha, habraacyada hawlgalka iyo tallaabooyinka badbaadada ee khuseeya ayaa loo baahan yahay in loo hoggaansamo si loo xaqiijiyo badbaadada hawlgalka.
