Intshayelelo
I-5-Fluoro-2-nitrotoluene i-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: I-5-fluoro-2-nitrotoluene ayinambala okanye ikristale etyheli.
- Iimpawu zeMichiza: I-5-fluoro-2-nitrotoluene inozinzo oluhle lweekhemikhali kwaye akulula ukuguquguquka.
Sebenzisa:
- I-Chemical intermediates: I-5-fluoro-2-nitrotoluene ingasetyenziswa njengendawo ephakathi kwi-organic synthesis ye-synthesis yezinye izinto eziphilayo.
Indlela:
I-5-Fluoro-2-nitrotoluene inokwenziwa ngoku:
Ngaphantsi kweemeko ze-alkaline, i-2-chlorotoluene yaphendulwa nge-hydrogen fluoride ukuze ifumane i-5-fluoro-2-chlorotoluene, ize iphendule nge-nitric acid ukuze ifumane imveliso ekujoliswe kuyo 5-fluoro-2-nitrotoluene.
Xa kukho utywala, i-2-nitrotoluene iphendulwa nge-hydrogen bromide, emva koko iphendule nge-hydrogen fluoride, kwaye ekugqibeleni imveliso ilungiswe ngokuchithwa kwamanzi.
Ulwazi ngoKhuseleko:
- I-5-Fluoro-2-nitrotoluene yikhemikhali enobunzima kwesikhumba kunye namehlo, ngoko gqoka iiglavu ezikhuselayo kunye nezibuko ukuze ugweme ukudibanisa ngokuthe ngqo.
- Ingqalelo kufuneka ihlawulwe kumanyathelo okuthintela umlilo kunye nokudubula ngexesha lokusetyenziswa kunye nokuphathwa, kwaye ugweme ukudibana namadangatye avulekileyo, amaqondo obushushu aphezulu okanye eminye imithombo yomlilo.
- Nceda ugcine kwaye uthuthe ngokufanelekileyo, kude ne-oxidants kunye nezinto ezinokutsha.
- Kwimeko yokungeniswa okanye ukuphefumla, funa unyango ngokukhawuleza kwaye unike ulwazi malunga nekhemikhali.
