Isingeniso
I-2-nitrobenzenesulfonyl chloride (2-nitrobenzenesulfonyl chloride) iyinhlanganisela yemvelo enefomula yamakhemikhali ethi C6H4ClNO3S. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
1. Imvelo:
I-2-nitrobenzensulfonyl chloride iyikristale ephuzi eqinile enephunga elimnandi. Ayincibiliki kahle emanzini, kodwa incibilika kalula kuzincibilikisi zemvelo. Ngaphansi kwezinga lokushisa eliphezulu, izimo ezikhanyayo nezinomswakama, i-2-nitrobenzensulfonyl chloride ingase ibole.
2. Sebenzisa:
I-2-nitrobenzenesulfonyl chloride ivamise ukusetshenziswa njenge-reagent ebalulekile ku-organic synthesis. Ingasetshenziselwa ukuhlanganisa ezinye izinhlanganisela eziphilayo, njenge-O-nitrobenzenesulfonamide nokunye. Ngaphezu kwalokho, ingasetshenziswa futhi njengendawo ephakathi yamadayi, ama-pigment kanye nezibulala-zinambuzane.
3. Indlela yokulungiselela:
Ukulungiswa kwe-2-nitrobenzenesulfonyl chloride kuvame ukutholwa ngokusabela i-p-nitrobenzene sulfonic acid ne-thionyl chloride ewuketshezi. Ukusabela kwenziwa ekushiseni okuphansi, futhi umkhiqizo wokusabela uvame ukuhlukaniswa yi-crystallization.
4. Ulwazi Lokuphepha:
I-2-nitrobenzensulfonyl chloride iyacasula futhi kufanele igcinwe kude nokuthintana kwamehlo nesikhumba. Naka izindlela zokuzivikela ngesikhathi sokusebenza, njengokugqoka amagilavu okuvikela amakhemikhali kanye nezibuko. Gwema ukuthintana nama-oxidants kanye nezinto ezivuthayo ngesikhathi sokugcina nokuphatha ukuze uvimbele ingozi yomlilo nokuqhuma. Ngesikhathi usebenzisa noma ulahla, sicela ulandele imithethonqubo efanele kanye nemihlahlandlela yokusebenza kokuphepha.
