Intangiriro

Pentane. Imiterere yacyo niyi ikurikira:

Ntibisanzwe hamwe numuti mwinshi kama ariko ntabwo ukoresheje amazi.

 

Ibikoresho bya shimi: N-pentane ni hydrocarubone ya alifatique yaka umuriro kandi ifite flash point nkeya hamwe nubushyuhe bwa autoignition. Irashobora gutwikwa mu kirere kugirango itange karuboni n'amazi. Imiterere yacyo iroroshye, kandi n-pentane irakora hamwe nibintu bisanzwe bisanzwe.

 

Imikoreshereze: N-pentane ikoreshwa cyane mubushakashatsi bwa chimique, gutegura ibishishwa hamwe nuruvange rwa solvent, kandi nigikoresho cyingenzi mubucuruzi bwa peteroli.

 

Uburyo bwo kwitegura: n-pentane iboneka cyane mugucamo no kuvugurura mugikorwa cyo gutunganya peteroli. Ibikomoka kuri peteroli byakozwe nibi bikorwa birimo n-pentane, bishobora gutandukanywa no kwezwa no kubitobora kugirango ubone n-pentane.

 

Amakuru yumutekano: n-pentane namazi yaka kandi agomba kubikwa kure yumuriro nubushyuhe bwinshi. Igomba gukoreshwa ahantu hafite umwuka mwiza kandi ukirinda guhura ningingo zikomeye za okiside. Kumara igihe kinini kuri n-pentane bishobora gutera uruhu rwumye kandi rukarakara, kandi hagomba gufatwa ingamba zikwiye zo gukingira nka gants na gogles. Mugihe uhumeka kubwimpanuka cyangwa guhura nuruhu na n-pentane, shaka ubufasha bwihuse.
