Intshayelelo
I-m-Nitrobenzenesulfonyl chloride yikhompawundi ephilayo enefomula yemichiza eyi-C6H4ClNO4S. Oku kulandelayo kukwazisa ngeepropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-m-nitrobenzene sulfonyl chloride:
Indalo:
m-Nitrobenzenesulfonyl chloride yikristale emthubi enevumba elinukayo. Izinzile kwiqondo lokushisa, kodwa ukusabela kokubola kwenzeka xa kushushu. Le khompawundi inokutsha kwaye ayinyibiliki emanzini, kodwa inokunyibilika kwizinyibilikisi zendalo.
Sebenzisa:
I-m-Nitrobenzenesulfonyl chloride yinto ebalulekileyo ephakathi kwi-organic synthesis. Isetyenziswa ngokuqhelekileyo kwi-synthesis ye-organic compounds efana namayeza, idayi kunye nezibulala-zinambuzane. Ukongezelela, inokusetyenziswa njenge-reagent ye-chlorination, i-reagent yokususa i-thiols, kunye ne-reagent ebalulekileyo kuhlalutyo lwamachiza.
Indlela:
I-m-Nitrobenzenesulfonyl chloride ingalungiswa ngokusabela kwe-iodination ye-p-nitrobenzenesulfonyl chloride. Inyathelo elithile kukunyibilikisa i-nitrophenylthionyl chloride kwi-chloroform, emva koko wongeze iodide ye-sodium kunye nenani elincinci le-iodide ye-hydrogen, kwaye ushushu ukuphendula ixesha elithile ukuze ufumane i-m-nitrobenzenesulfonyl chloride.
Ulwazi ngoKhuseleko:
I-m-Nitrobenzenesulfonyl chloride yityhefu enokucaphukisa ulusu, amehlo kunye nendlela yokuphefumla. Xa usebenza, kuphephe ukudibana nolusu kunye namehlo, kwaye uqinisekise ukuba olu tyando lwenziwa kwindawo engenamoya. Izixhobo zokhuselo lomntu ezifana neeglavu zokukhusela, iiglasi zokhuseleko kunye neemaski zokukhusela kufuneka zinxitywe xa usebenzisa into. Ukongeza, i-m-nitrobenzene sulfonyl chloride kufuneka igcinwe ngokufanelekileyo, kude nemithombo yomlilo kunye ne-oxidants, kwaye ugweme ukudibanisa nezinto ezinokutsha. Kwimeko yokuphatha kakubi okanye ingozi, funa unyango ngokukhawuleza kwaye uthathe ifomu yedatha yokhuseleko yekhomponi uyise esibhedlele.
