Isingeniso

I-Cyclopentadiene (C5H8) iwuketshezi olungenambala, olunephunga elimnandi. I-olefin engazinzile kakhulu eyenziwe nge-polymerized futhi icishe ivuthe.

I-Cyclopentadiene inezinhlobonhlobo zezicelo ocwaningweni lwamakhemikhali. Ingasetshenziswa futhi njengento eluhlaza yama-polymers nama-rubber ukuthuthukisa izakhiwo zabo zomzimba namakhemikhali.

Kunezindlela ezimbili eziyinhloko zokulungiselela i-cyclopentadiene: eyodwa ikhiqizwa ngokuqhekeka kwamafutha kapharafini, kanti enye ilungiswa ukusabela kwe-isomerization noma ukusabela kwe-hydrogenation kwe-olefins.

I-Cyclopentadiene iguquguquka kakhulu futhi iyavutha, futhi iwuketshezi oluvuthayo. Enqubweni yokugcina nokuthutha, izinyathelo zokuvimbela umlilo nokuqhuma kufanele zithathwe ukuze kugwenywe ukuthintana namalangabi avulekile kanye namazinga okushisa aphezulu. Gqoka okokuvikela okufanele okufana namagilavu, izibuko, nezingubo eziqhumayo lapho usebenzisa futhi uphethe i-cyclopentadiene. Ngesikhathi esifanayo, ukunakekelwa kufanele kuthathwe ukuze ugweme ukuthintana nesikhumba kanye ne-inhalation ye-vapor yayo, ukuze ungabangeli ukucasuka kanye nobuthi. Esimeni lapho kuvuza ngengozi, nqamula umthombo wokuvuza ngokushesha futhi uwuhlanze ngezinto ezifanele zokumunca. Emkhiqizweni wezimboni, izinqubo zokuphepha ezifanele kanye nezinyathelo kufanele zilandelwe ukuze kuqinisekiswe ukuphepha kokusebenza.
