Intangiriro

Cyclopentane ni amazi atagira ibara afite impumuro idasanzwe. Ni hydrocarubone ya alifatique. Ntishobora gushonga mumazi ariko irashobora gushonga mumashanyarazi menshi.

 

Cyclopentane ifite imbaraga zo gukemuka hamwe nuburyo bwiza bwo kwangirika, kandi akenshi ikoreshwa nkigisubizo kama kama muri laboratoire. Nibisanzwe bikoreshwa mugukora isuku bishobora gukoreshwa mugukuraho amavuta numwanda.

 

Uburyo busanzwe bwo gukora cyclopentane ni binyuze muri dehydrogenation ya alkane. Uburyo busanzwe ni ukubona cyclopentane mugucamo ibice biva kuri peteroli.

 

Cyclopentane ifite umutekano muke, ni amazi yaka umuriro ashobora gutera umuriro cyangwa guturika byoroshye. Guhura numuriro ufunguye hamwe nubushyuhe bwo hejuru bigomba kwirindwa mugihe ukoresheje. Iyo ukoresheje cyclopentane, igomba guhumeka neza kandi ikirinda guhumeka cyangwa guhura nuruhu n'amaso.
