Intshayelelo

I-2-nitropropane. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-2-nitropropane:

 

Umgangatho:

- Imbonakalo: Ulwelo olungenambala

-Ukunyibilika: Inyibilika kwizinyibilikisi zendalo ezifana ne-ethanol, i-ether, iacetone, njl.

 

Sebenzisa:

- I-2-Nitropropane isetyenziswa ikakhulu njengenxalenye yeziqhushumbisi kunye ne-propellants, kwaye isetyenziswa ngokuqhelekileyo ekwenzeni iziqhushumbisi kunye ne-rocket fuel.

- Ikwasetyenziswa njengesiqalo esibalulekileyo sokwenziwa kweekhompawundi ze-organic ukulungiselela ezinye iikhemikhali.

 

Indlela:

- I-2-Nitropropane inokulungiswa ngokuphendula kwe-glycerol kunye ne-nitric acid. I-Glycerol yongezwa kwi-nitric acid, ilandelwa yimpendulo yokufudumala, ekugqibeleni inika i-2-nitropropane.

 

Ulwazi ngoKhuseleko:

- I-2-Nitropropane yikhompawundi eqhumayo kwaye kufuneka iphathwe ngononophelo ukuphepha ukuvezwa kwimithombo enokutsha efana namadangatye avulekileyo, ubushushu obuphezulu, okanye iintlantsi zombane.

- Ukutshisa kunokwenzeka xa udibana nolusu kunye namehlo, unxibe iiglavu zokukhusela kunye neglasi xa usebenza.

- Zigcine kude nezinto ezixutywe ne-oksijini kunye nezinto ezinokutsha xa usebenzisa okanye ugcina, kwaye ugcine indawo enomoya owaneleyo.

- Kwimeko yokungenwa ngengozi okanye ukuphefumla, funa unyango ngokukhawuleza kwaye unikezele ngephepha ledatha yokhuseleko kwireferensi kagqirha wakho.

 

Sebenzisa i-2-nitropropane ngokuqaphela kwaye ulandele iinkqubo zokusebenza ezikhuselekileyo xa usebenza.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
