Intshayelelo
I-1-Bromo-4-nitrobenzene i-organic compound kunye ne-chemical formula C6H4BrNO2. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukuqulunqwa kunye nolwazi lokhuseleko:
Indalo:
I-1-Bromo-4-nitrobenzene yikristale emthubi ephaphathekileyo enencasa yealmond ekrakra. Iqinile kwiqondo lobushushu begumbi kwaye inendawo ephezulu yokunyibilika kunye nenqanaba lokubila. Ayinyibiliki kakuhle emanzini, kodwa inyibilika kwizinyibilikisi zendalo ezifana neealkoholi kunye ne-ethers.
Sebenzisa:
I-1-Bromo-4-nitrobenzene inoluhlu olubanzi lokusetyenziswa kwi-organic synthesis. Ingasetyenziswa njengendawo ephakathi yokwenziwa kwezinye izinto eziphilayo, ezifana neziyobisi, idayi kunye nezibulali-zinambuzane. Isenokusetyenziswa njengesixhobo sokuqala kwiindlela zokwenziwa kwee-antibiotics, iihomoni kunye nezithambiso.
Indlela yokulungiselela:
Ukulungiswa kwe-1-Bromo-4-nitrobenzene kunokwenziwa ngamanyathelo alandelayo:
1. i-nitric acid isabela nge-bromobenzene ukwenza i-4-nitrobromobenzene.
2. I-4-nitrobromobenzene iguqulelwa kwi-1-Bromo-4-nitrobenzene ngokusabela kokunciphisa.
Ulwazi ngoKhuseleko:
I-1-Bromo-4-nitrobenzene yinto enobungozi ephazamisayo kunye ne-carcinogenic. Nxiba iiglavu zokukhusela kunye neeglasi ukuphepha ukudibana nolusu kunye namehlo. Kuphephe ukuphefumla uthuli lwayo okanye umphunga kwaye uqinisekise ukuba isetyenziswa kwindawo engena umoya. Ekugcinweni nasekuphatheni, ukulandela iinkqubo ezifanelekileyo zokhuseleko.
