Intshayelelo
I-1-Iodo-3-nitrobenzene, eyaziwa ngokuba yi-3-nitro-1-iodobenzene, i-organic compound. Oku kulandelayo kukwazisa ngeepropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-1-iodo-3-nitrobenzene:
Umgangatho:
- Ukubonakala: I-1-iodo-3-nitrobenzene yikristale ephuzi okanye i-crystalline powder.
- Ukunyibilika: I-1-Iodo-3-nitrobenzene i-soluble kancinane kwi-ethanol, i-acetone, kunye ne-chloroform, kwaye iphantse inganyibiliki emanzini.
Sebenzisa:
- I-Chemical synthesis: I-1-iodo-3-nitrobenzene ingasetyenziselwa ukudibanisa ezinye izinto eziphilayo, ezifana ne-amines enuka kamnandi.
- Izibulali zinambuzane: Ingasetyenziswa njengendawo ephakathi kwimichiza yokutshabalalisa izinambuzane, imichiza yokutshabalalisa ukhula kunye nezinye izitshabalalisi.
Indlela:
Indlela yokulungiselela i-1-iodo-3-nitrobenzene ingasebenzisa i-3-nitrobenzene njengento eluhlaza kwaye iqhutywe nge-iodization reaction. Indlela eqhelekileyo yokulungiselela ukunyibilikisa i-3-nitrobenzene kunye ne-iodine kwisisombululo se-sodium hydroxide phambi kwe-sodium carbonate, uze udibanise ngokuthe ngcembe i-chloroform yokusabela, kwaye ekugqibeleni uphathe nge-dilute hydrochloric acid ukufumana i-1-iodo-3-nitrobenzene.
Ulwazi ngoKhuseleko:
I-1-iodo-3-nitrobenzene yikhemikhali eyityhefu eyingozi kumzimba womntu kunye nokusingqongileyo
- Gwema ukudibana: Ukudibana kwesikhumba, ukudibana kwamehlo, kunye nokuphefumla uthuli okanye igesi ye-1-iodo-3-nitrobenzene kufuneka igwenywe.
- Amanyathelo okhuseleko: Nxiba izixhobo ezifanelekileyo zokukhusela ezifana neeglavu zaselebhu, iiglasi, kunye nemaski xa usebenza.
- Iimeko zokungenisa umoya: Kubalulekile ukuqinisekisa ukuba indawo yokusebenza ingena kakuhle ukuze kuncitshiswe ukuxinana kweegesi ezinetyhefu.
- Ukugcinwa nokuphatha: Kufuneka igcinwe kwisikhongozeli esingangeni moya, kude nomlilo namaqondo obushushu aphezulu. Inkunkuma kufuneka ilahlwe ngokwemigaqo efanelekileyo.
I-1-Iodo-3-nitrobenzene iyingozi, kwaye izikhokelo zokusebenza kokhuseleko lweekhemikhali ezifanelekileyo kufuneka zifundwe ngokucophelela kwaye zilandelwe ngaphambi kokusetyenziswa.
