Taw qhia

Octane yog ib qho organic compound. Nws cov khoom yog raws li nram no:

1. Cov tsos: cov kua tsis muaj xim

4. Ceev: 0.69 g / cm³

5. Flammability: flammable

Octane yog ib qho kev sib xyaw uas feem ntau yog siv hauv cov roj thiab cov kuab tshuaj. Nws cov kev siv tseem ceeb suav nrog:

1. Roj additives: Octane yog siv nyob rau hauv roj av raws li ib tug txheej txheem compound rau octane tooj kuaj los soj ntsuam cov anti-knock kev kawm ntawm roj av.

2. Lub cav roj: Raws li cov khoom siv roj nrog lub peev xwm ua kom muaj zog, nws tuaj yeem siv rau hauv cov tshuab ua haujlwm siab lossis cov tsheb sib tw.

3. Cov kuab tshuaj: Nws tuaj yeem siv los ua cov kuab tshuaj hauv thaj chaw degreasing, ntxuav thiab xab npum.

Lub ntsiab kev npaj ntawm octane yog raws li nram no:

1. Extracted los ntawm Roj: Octane tuaj yeem raug rho tawm thiab muab rho tawm los ntawm roj av.

2. Alkylation: Los ntawm alkylating octane, ntau octane tebchaw tuaj yeem ua ke.

1. Octane yog cov kua hluav taws kub thiab yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav, qhov cua zoo, kom deb ntawm qhov hluav taws kub thiab oxidants.

2. Thaum siv octane, hnav cov khoom tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv.

3. Tsis txhob kov cov tawv nqaij, qhov muag, thiab ua pa ntawm octane.

4. Thaum tuav octane, tsis txhob tsim hluav taws xob lossis hluav taws xob zoo li qub uas tuaj yeem ua rau hluav taws kub lossis tawg.

Yav dhau los: Pentane (CAS # 109-66-0)
