Isingeniso

I-Octane iyinhlanganisela yezinto eziphilayo. Izici zayo zimi kanje:

 

1. Ukubukeka: uketshezi olungenambala

4. Ukuminyana: 0.69 g/cm³

5. Ukuvutha: ukuvutha

 

I-Octane iyinhlanganisela esetshenziswa kakhulu kumafutha nezincibilikisi. Ukusetshenziswa kwayo okuyinhloko kuhlanganisa:

1. Izithasiselo zikaphethiloli: I-Octane isetshenziswa kuphethiloli njengenhlanganisela evamile yokuhlolwa kwenombolo ye-octane ukuze kuhlolwe ukusebenza kukaphethiloli okuvimbela ukungqongqoza.

2. Uphethiloli wenjini: Njengengxenye kaphethiloli enamandla omlilo onamandla, ingasetshenziswa ezinjinini ezisebenza kahle kakhulu noma ezimotweni zomjaho.

3. I-solvent: Ingasetshenziswa njenge-solvent emikhakheni yokuhlanza, ukuwasha kanye ne-detergent.

 

Izindlela eziyinhloko zokulungiselela i-octane zimi kanje:

1. Ikhishwe Kuwoyela: I-Octane ingahlukaniswa futhi ikhishwe ku-petroleum.

2. I-Alkylation: Nge-alkylating octane, izinhlanganisela ze-octane eziningi zingahlanganiswa.

 

1. I-Octane iwuketshezi oluvutha umlilo futhi kufanele igcinwe endaweni epholile, eyomile, enomoya omuhle, kude nokushisa kanye nama-oxidants.

2. Lapho usebenzisa i-octane, gqoka izinto zokuzivikela ezifanele njengamagilavu, izibuko, nezingubo zokuzivikela.

3. Gwema ukuthinta i-octane nesikhumba, amehlo, nemigudu yokuphefumula.

4. Uma uphethe i-octane, gwema ukukhiqiza izinhlansi noma ugesi omile ongabangela umlilo noma ukuqhuma.

    • Bhala umyalezo wakho lapha futhi usithumelele wona
