Pentane. Lintho tsa eona ke tse latelang:

E kopane le lihlapolli tse ngata tsa tlhaho empa eseng ka metsi.

 

Lits'ebetso tsa Lik'hemik'hale: N-pentane ke aliphatic hydrocarbon e tukang 'me e na le khanya e tlase le mocheso oa autoignition. E ka chesoa moeeng ho hlahisa carbon dioxide le metsi. Sebopeho sa eona se bonolo, 'me n-pentane e sebetsa hantle ka metsoako e tloaelehileng ea lintho tse phelang.

 

Lisebelisoa: N-pentane e sebelisoa haholo litekong tsa lik'hemik'hale, ho lokisoa ha li-solvents le metsoako ea solvent, hape ke thepa ea bohlokoa e tala indastering ea peterole.

 

Mokhoa oa ho itokisa: n-pentane e fumanoa haholo-holo ka ho phunyeha le ho fetola mokhoa oa ho hloekisa peterole. Lihlahisoa tsa petroleum tse hlahisoang ke mekhoa ena li na le n-pentane, e ka arohanngoa le ho hloekisoa ka distillation ho fumana n-pentane e hloekileng.

 

Tlhahisoleseding ea polokeho: n-pentane ke mokelikeli o tukang 'me o lokela ho behoa hole le malakabe a bulehileng le mocheso o phahameng. E lokela ho sebelisoa sebakeng se nang le moea o motle 'me u qobe ho kopana le li-oxidizing tse matla. Ho pepesehela n-pentane ka nako e telele ho ka baka letlalo le omeletseng le le halefileng, 'me mehato e nepahetseng ea tšireletso e kang li-gloves le likhalase li lokela ho nkoa. Haeba motho a ka hema ka phoso kapa a kopana le n-pentane, batla thuso ea bongaka hang-hang.
