Isingeniso

2-nitropropane. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2-nitropropane:

 

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala

- I-Solubility: Incibilika kuzincibilikisi eziphilayo njenge-ethanol, i-ether, i-acetone, njll.

 

Sebenzisa:

- I-2-Nitropropane isetshenziswa kakhulu njengengxenye yeziqhumane nama-propellants, futhi ivame ukusetshenziswa ekwenzeni iziqhumane kanye nophethiloli we-rocket.

- Iphinde isetshenziswe njengesiqalo esibalulekile sokuhlanganiswa kwezinto eziphilayo ukuze kulungiswe amanye amakhemikhali.

 

Indlela:

- I-2-Nitropropane ingalungiswa ngokusabela kwe-glycerol ne-nitric acid. I-Glycerol yengezwa ku-nitric acid, ilandelwa ukusabela kokushisa, okugcina kunikeza i-2-nitropropane.

 

Ulwazi Lokuphepha:

- I-2-Nitropropane iyinhlanganisela yeziqhumane futhi kufanele iphathwe ngokucophelela ukugwema ukuchayeka emithonjeni evuthayo njengamalangabi avulekile, izinga lokushisa eliphezulu, noma izinhlansi zikagesi.

- Ukusha kungase kwenzeke lapho kuthinta isikhumba namehlo, gqoka amagilavu ​​okuzivikela kanye nezibuko lapho usebenza.

- Ziqhelelanise nama-oxidants nezinto ezivuthayo lapho usebenzisa noma ugcina, futhi ugcine indawo enomoya omuhle.

- Uma ungenwa ngephutha noma uhogele umoya, funa usizo lwezokwelapha ngokushesha futhi unikeze ishidi ledatha yokuphepha ukuze uthole inkomba kadokotela wakho.

 

Sebenzisa i-2-nitropropane ngokuqapha futhi ulandele izinqubo zokusebenza eziphephile lapho usebenza.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
