Intshayelelo
Yinto ephilayo ene-formula C7H8N2O4S. Ingumgubo omhlophe wekristale kunye ne-asidi ebuthakathaka. Oku kulandelayo yinkcazo yeepropati, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko lwekhompawundi:
Indalo:
-Imbonakalo: Umgubo omhlophe wekristale
-Ubunzima bemolekyuli: 216.21g / mol
-indawo yokunyibilika: 168-170 ℃
-Ukunyibilika: Inyibilika kancinci emanzini, kulula ukuyinyibilika kwizinyibilikisi zendalo ezifana ne-ethanol kunye ne-acetone.
-asidi kunye ne-alkaline: i-asidi ebuthakathaka
Sebenzisa:
-isetyenziswa ikakhulu kwi-organic synthesis njenge-reagent ebalulekileyo kunye nephakathi.
-Ingasetyenziselwa ukulungiselela iikhemikhali ezifana neziyobisi, idayi kunye nezixhobo zepolymer.
Indlela yokulungiselela:
Inokwenziwa ngala manyathelo alandelayo: br>1. Okokuqala, phantsi kweemeko ezifanelekileyo zokuphendula, i-methyl bromide kunye ne-p-nitrobenzene sulfonamide zisabela zenze i-methyl ester.
2. Emva koko, i-methyl ester iphendulwa ngesisombululo se-alkaline ukufumana ityuwa.
Ulwazi ngoKhuseleko:
-kufuneka igcinwe kwindawo eyomileyo, kwindawo engenamoya, kwaye uphephe ukukhanya kwelanga.
-Ngexesha lokusebenza, thintela ukudibanisa nolusu kunye namehlo. Ukuba ibonakalisiwe, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune unyango.
-Nxiba izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu, iiglasi zokhuseleko kunye nempahla yokukhusela xa uphethe ikhompawundi.
-Musa ukuxuba le khompawundi kunye ne-oxidants eqinile kunye ne-acids eqinile, kuba inokubangela ukusabela okuyingozi.
-Ngaphambi kokusebenzisa okanye ukuphatha i-compound, imiyalelo yobugcisa bokhuseleko enikezelwe ngumthengisi kufuneka ifundwe ngononophelo.
