Isingeniso

I-Cyclopentane iwuketshezi olungenambala olunephunga elingavamile. I-aliphatic hydrocarbon. Ayincibiliki emanzini kodwa ingancibilika kuzincibilikisi eziningi eziphilayo.

 

I-Cyclopentane ine-solubility enhle kanye nezakhiwo ezinhle kakhulu zokunciphisa amafutha, futhi ivame ukusetshenziswa njenge-solvent yokuhlola ephilayo elabhorethri. Futhi i-ejenti yokuhlanza evame ukusetshenziswa engasetshenziswa ukususa amafutha nokungcola.

 

Indlela evamile yokukhiqiza i-cyclopentane ngokusebenzisa i-dehydrogenation ye-alkanes. Indlela evamile ukuthola i-cyclopentane ngokuhlukanisa kusuka ku-petroleum cracking gas.

 

I-Cyclopentane inengozi ethile yokuphepha, iwuketshezi oluvuthayo olungabangela kalula umlilo noma ukuqhuma. Ukuthintana namalangabi avulekile kanye nezinto ezishisa kakhulu kufanele kugwenywe uma usebenzisa. Lapho ubamba i-cyclopentane, kufanele ingene kahle futhi igweme ukuhogela noma ukuthintana nesikhumba namehlo.
