| Izimpawu Eziyingozi | Xi - Irritant |
| Inothi Lengozi | Iyacasula |
Isingeniso
Kuyinhlanganisela yemvelo enefomula C7H8N2O4S. I-crystalline powder emhlophe ene-asidi ebuthakathaka. Okulandelayo incazelo yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwenhlanganisela:
Imvelo:
-Ukubukeka: I-crystalline powder emhlophe
Isisindo samangqamuzana: 216.21g/mol
-indawo yokuncibilika: 168-170 ℃
-Ukunyibilika: Kuncibilika kancane emanzini, kulula ukuncibilika kuzincibilikisi zemvelo ezifana ne-ethanol ne-acetone
-i-asidi ne-alkali: i-asidi ebuthakathaka
Sebenzisa:
-isetshenziswa kakhulu ekuhlanganiseni okuphilayo njenge-reagent ebalulekile futhi ephakathi.
-Ingasetshenziselwa ukulungisa amakhemikhali afana nezidakamizwa, odayi nezinto ze-polymer.
Indlela Yokulungiselela:
Ingahlanganiswa ngezinyathelo ezilandelayo: br>1. Okokuqala, ngaphansi kwezimo ezifanele zokusabela, i-methyl bromide ne-p-nitrobenzene sulfonamide ziyasabela ukuze zenze i-methyl ester.
2. Bese, i-methyl ester iphendulwa ngesisombululo se-alkaline ukuze kutholwe usawoti.
Ulwazi Lokuphepha:
-kufanele igcinwe endaweni eyomile, engenawo umoya futhi igweme ukukhanya kwelanga.
-Ngesikhathi sokusebenza, gwema ukuthintana nesikhumba namehlo. Uma kuveziwe, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezempilo.
-Gqoka izinto zokuzivikela ezifanele ezifana namagilavu, izibuko zokuphepha nezingubo zokuzivikela lapho uphatha inhlanganisela.
-Ungaxubani le nhlanganisela nama-oxidants aqinile nama-acids aqinile, ngoba angabangela ukusabela okuyingozi.
-Ngaphambi kokusebenzisa noma ukuphatha inhlanganisela, imiyalelo yezobuchwepheshe yokuphepha enikezwe umphakeli kufanele ifundwe ngokucophelela.
