Isingeniso

I-m-Nitrobenzenesulfonyl chloride iyinhlanganisela ye-organic ifomula yayo yamakhemikhali ithi C6H4ClNO4S. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungisa kanye nolwazi lokuphepha lwe-m-nitrobenzene sulfonyl chloride:

 

Imvelo:

I-m-Nitrobenzenesulfonyl chloride iyikristalu ephuzi enephunga elimnandi. Iyazinzile ekamelweni lokushisa, kodwa ukusabela kokubola kwenzeka lapho kushisa. Le nhlanganisela iyavutha futhi ayincibiliki emanzini, kodwa ingancibilika kuma-organic solvents.

 

Sebenzisa:

I-m-Nitrobenzenesulfonyl chloride iyingxenye ebalulekile yokwenziwa kwezinto eziphilayo. Ivame ukusetshenziswa ekuhlanganiseni izinto eziphilayo ezifana nemithi, odayi kanye nezibulala-zinambuzane. Ngaphezu kwalokho, ingasetshenziswa njenge-reagent ye-chlorination, i-reagent yokususa ama-thiols, kanye ne-reagent ebalulekile ekuhlaziyweni kwamakhemikhali.

 

Indlela:

m-Nitrobenzenesulfonyl chloride ingalungiswa ngokusabela kwe-iodination ye-p-nitrobenzenesulfonyl chloride. Isinyathelo esiqondile ukuncibilikisa i-nitrophenylthionyl chloride ku-chloroform, bese wengeza iodide ye-sodium nenani elincane le-hydrogen iodide, bese ushisisa ukusabela isikhathi esithile ukuze uthole i-m-nitrobenzenesulfonyl chloride.

 

Ulwazi Lokuphepha:

I-m-Nitrobenzenesulfonyl chloride iwushevu ocunula isikhumba, amehlo kanye nendlela yokuphefumula. Lapho usebenza, gwema ukuthinta isikhumba namehlo, futhi uqinisekise ukuthi ukuhlinzwa kwenziwa endaweni enomoya omuhle. Izinto zokuzivikela ezinjengamagilavu ​​okuzivikela, izibuko zokuphepha namamaski okuzivikela kufanele zigqokwe lapho kusetshenziswa into. Ngaphezu kwalokho, i-m-nitrobenzene sulfonyl chloride kufanele igcinwe kahle, kude nemithombo yomlilo nama-oxidants, futhi igweme ukuthintana nezinto ezivuthayo. Esimeni sokungaphathwa kahle noma ingozi, funa usizo lwezokwelapha ngokushesha futhi uthathe ifomu ledatha yezokuphepha yenkomponi uyiyise esibhedlela.
