Intshayelelo

I-Cyclopentadiene (C5H8) lulwelo olungenambala, olunevumba elimnandi. Yi-olefin engazinzanga kakhulu epholymerized kakhulu kwaye noko inokutsha.

I-Cyclopentadiene inoluhlu olubanzi lwezicelo kuphando lweekhemikhali. Isenokusetyenziswa njengento ekrwada yeepolymers kunye neerubha ukuphucula iimpawu zabo zomzimba kunye neekhemikhali.

Kukho iindlela ezimbini eziphambili zokulungiselela i-cyclopentadiene: enye iveliswa ngokuqhekeka kweoli yeparafini, kwaye enye ilungiswe yi-isomerization reaction okanye i-hydrogenation reaction ye-olefins.

I-Cyclopentadiene iguquguquka kakhulu kwaye iyatsha, kwaye ilulwelo olunokutsha. Kwinkqubo yokugcina kunye nokuthutha, amanyathelo okukhusela umlilo kunye nokuqhuma kufuneka kuthathwe ukuphepha ukudibanisa nomlilo ovulekileyo kunye nokushisa okuphezulu. Nxiba izixhobo ezifanelekileyo zokukhusela ezinje ngeeglavu, iiglasi, kunye nempahla eqhumayo xa usebenzisa naxa uphethe i-cyclopentadiene. Ngexesha elifanayo, kufuneka kuthathelwe ingqalelo ukuphepha ukudibanisa nesikhumba kunye ne-inhalation ye-vapors yayo, ukwenzela ukuba kungabangela ukucaphuka kunye netyhefu. Xa kukho ukuvuza ngengozi, nqumla umthombo wokuvuza ngokukhawuleza kwaye ucoce ngezinto ezifanelekileyo zokufunxa. Kwimveliso yemizi-mveliso, iinkqubo zokusebenza ezifanelekileyo zokhuseleko kunye namanyathelo kufuneka zithotyelwe ukuqinisekisa ukhuseleko lokusebenza.

Ngaphambili: Cyclohexanone(CAS#108-94-1)

Okulandelayo: Cyclopentaone(CAS#120-92-3)
