Intangiriro

Octane nikintu kama. Imiterere yacyo niyi ikurikira:

1. Kugaragara: amazi adafite ibara

4. Ubucucike: 0,69 g / cm³

5. Gutwikwa: gutwikwa

Octane ni uruganda rukoreshwa cyane cyane mu bicanwa no mumashanyarazi. Imikoreshereze yacyo nyamukuru irimo:

1. Ibyongeweho lisansi: Octane ikoreshwa muri lisansi nkigikoresho gisanzwe cyo gupima nimero ya octane kugirango isuzume imikorere ya anti-knock ya lisansi.

2. Amavuta ya moteri: Nkibikoresho bya lisansi ifite imbaraga zo gutwika, irashobora gukoreshwa muri moteri ikora cyane cyangwa mumodoka yo kwiruka.

3. Umuti: Irashobora gukoreshwa nkigishishwa mubice byo gutesha agaciro, gukaraba no gukaraba.

Uburyo nyamukuru bwo gutegura octane nuburyo bukurikira:

1. Yakuwe mu mavuta: Octane irashobora kwigunga no gukurwa muri peteroli.

2. Alkylation: Mugihe alkylating octane, ibice byinshi bya octane birashobora guhuzwa.

1. Octane ni amazi yaka kandi agomba kubikwa ahantu hakonje, humye, gahumeka neza, kure yumuriro na okiside.

2. Mugihe ukoresheje octane, ambara ibikoresho bikingira bikingira nka gants, indorerwamo, n imyenda ikingira.

3. Irinde guhura na octane n'uruhu, amaso, n'inzira z'ubuhumekero.

4. Mugihe ukoresha octane, irinde kubyara ibishashi cyangwa amashanyarazi ahamye ashobora gutera umuriro cyangwa guturika.

Mbere: Pentane (CAS # 109-66-0)
