Heptane (CAS # 142-82-5)

ubuziranenge
Amazi adahinduka. Kudashonga mumazi, gushonga muri alcool, ntibyumvikana muri ether, chloroform. Umwuka wacyo ukora imvange iturika hamwe numwuka, bitera gutwikwa no guturika mugihe umuriro ugurumana nimbaraga nyinshi. Irashobora kwitwara cyane hamwe na okiside.

Uburyo
Inganda-n-heptane irashobora kwezwa no gukaraba aside sulfurike yibanze, methanol azeotropic distillation hamwe nubundi buryo.

Koresha
Ikoreshwa nka reagent yisesengura, moteri ya lisansi ikomanga igipimo cyibizamini, ibintu bifatika byo gusesengura chromatografique, hamwe na solve. Ikoreshwa nkigipimo cyo kumenya umubare wa octane, kandi irashobora no gukoreshwa nkibisindisha, ibishishwa hamwe nibikoresho fatizo bya synthesis.

umutekano
Imbeba itera inshinge LD50: 222mg / kg; imbeba yashizemo 2h LCso: 75000mg / m3. Ibintu byangiza ibidukikije, birashobora gutera umwanda umubiri wamazi nikirere, hamwe na bioaccumules muminyururu yingenzi yibiribwa kubantu, cyane cyane mumafi. Heptane irashobora gutera umutwe, isesemi, anorexia, kugenda gutangaje, ndetse no guta ubwenge no guhagarika umutima. Ubike mu bubiko bukonje, buhumeka. Birashoboka cyane umuriro. Irinde umuriro nubushyuhe. Ubushyuhe bwububiko ntibugomba kurenga 30 ° C. Irinde izuba ryinshi. Komeza ikintu gifunze neza. Igomba kubikwa ukwayo hamwe na okiside.
