He wai kala ʻole ʻo Cyclopentane me kahi ʻala ʻokoʻa. He aliphatic hydrocarbon. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai akā hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik.

 

Loaʻa i ka Cyclopentane ka solubility maikaʻi a me nā waiwai degreasing maikaʻi loa, a hoʻohana pinepine ʻia ma ke ʻano he mea hoʻokolohua hoʻokolohua kūlohelohe i loko o ka hale hana. He mea hoʻomaʻemaʻe maʻamau ia e hiki ke hoʻohana ʻia e wehe i ka momona a me ka lepo.

 

ʻO kahi ala maʻamau no ka hana ʻana i ka cyclopentane ma o ka dehydrogenation o nā alkanes. ʻO ke ala maʻamau ka loaʻa ʻana o ka cyclopentane ma ka haʻihaʻi ʻana mai ke kinoea pohā ʻaila.

 

Loaʻa i ka Cyclopentane kekahi pilikia palekana, he wai wela ia e hiki ke hana maʻalahi i ke ahi a pahū paha. Pono e pale ʻia ka pili ʻana me nā lapalapa ākea a me nā mea wela i ka wā e hoʻohana ai.
