Intshayelelo

I-3,4-Dichloronitrobenzene yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye neenkcukacha zokhuseleko:

 

Umgangatho:

- I-3,4-Dichloronitrobenzene yikristale engenambala okanye ikristale ekhanyayo etyheli kunye nevumba elinamandla lokufutha.

-Ayinyibiliki emanzini kwiqondo lobushushu begumbi, kodwa inyibilika kuninzi lwezinyibilikisi eziphilayo.

 

Sebenzisa:

- I-3,4-Dichloronitrobenzene ingasetyenziswa njenge-reagent yekhemikhali efana ne-substrate ye-nitrosylation reactions.

- Inokusetyenziswa kwakhona njenge-precursor kwi-synthesis yezinye izinto eziphilayo, ezifana ne-glyphosate, i-herbicide.

 

Indlela:

- I-3,4-Dichloronitrobenzene idla ngokulungiswa nge-chlorination ye-nitrobenzene. Indlela ethile yokulungiselela ingasebenzisa umxube we-sodium nitrite kunye ne-nitric acid, kwaye iphendule nge-benzene phantsi kweemeko ezifanelekileyo zokuphendula. Emva kokuphendula, imveliso ekujoliswe kuyo ihlanjululwa nge-crystallization kunye namanye amanyathelo.

 

Ulwazi ngoKhuseleko:

I-3,4-Dichloronitrobenzene inetyhefu kwaye inokubangela ingozi kwimpilo yabantu. Ukuba sesichengeni, ukuphefumla, okanye ukufunxa le nto kunokubangela ukucaphuka kwamehlo, ukuphefumla kunye nolusu.

- Le ngqungquthela kufuneka igcinwe kwindawo epholileyo, eyomileyo, epholileyo, kude nezinto ezinokutsha kunye ne-oxidizing agents.

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