Intshayelelo

I-2,5-Dichloronitrobenzene yi-organic compound. Yikristale engenambala ukuya kumthubi nevumba elikrakrayo. Oku kulandelayo kukwazisa ngeepropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-2,5-dichloronitrobenzene:

 

Umgangatho:

- Imbonakalo: Ayinambala ukuya kwiikristale ezityheli ezikhanyayo

-Ukunyibilika: Inyibilika kancinane emanzini kwaye inyibilika ngokulula kwizinyibilikisi eziphilayo ezinje ngotywala kunye neetha

 

Sebenzisa:

- I-2,5-Dichloronitrobenzene isetyenziswa ngokuqhelekileyo njengento yokuqala kwi-organic synthesis kwiilebhu zemichiza kwaye ingasetyenziselwa ukulungisa ezinye izinto eziphilayo.

 

Indlela:

- I-2,5-dichloronitrobenzene idla ngokulungiswa ngokuxutywa kwe-nitrification reaction ye-nitrobenzene.

- Kwilabhoratri, i-nitrobenzene inokutsalwa ngokusebenzisa umxube we-nitric acid kunye ne-nitrous acid ukunika ukusabela kwe-2,5-dichloronitrobenzene.

 

Ulwazi ngoKhuseleko:

- I-2,5-dichloronitrobenzene yinto enetyhefu, kwaye ukuvezwa kunye nokuphefumla umphunga wayo kunokuba yingozi empilweni. Kulumkele ukudibana ngqo nolusu, amehlo, kunye nomgudu wokuphefumla.

- Izixhobo zokukhusela zomntu ezifana neeglavu zokukhusela, izibuko, kunye neemaski kufuneka zigqitywe xa uphatha kunye nokuphatha i-2,5-dichloronitrobenzene.

- Kufuneka iqhutywe kwindawo enomoya kakuhle ukuphepha ukuphefumla umphunga.

- Inkunkuma kufuneka ilahlwe ngokuhambelana nemigaqo yendawo kwaye akufanele ilahlwe.
