inkcazelo emfutshane:

I-p-Toluenesulfonamide, ekwaziwa ngokuba yi-4-toluenesulfonamide, p-sulfonamide, toluene-4-sulfonamide, toluenesulfonamide, p-sulfamoyltoluene, yiflake emhlophe okanye igqabi lekristale yeChemicalbook, esetyenziselwa ukudibanisa ichloramine-T kunye neChloramphenicol, idayi yefluorescent, iplastiki , ii-synthetic resins, i-coatings, ii-disinfectants kunye nezikhanyisi zokulungisa iinkuni, njl.
I-p-Toluenesulfonamide yiplasitiki egqwesileyo eyomeleleyo yeplastiki ye-thermosetting, ilungele i-phenolic resin, i-melamine resin, i-urea-formaldehyde resin, i-polyamide kunye nezinye ii-resin. Umlinganiselo omncinci wokudibanisa unokuphucula ukuqhubekeka, wenze ukunyanga, kwaye unike imveliso iglosi elungileyo. I-p-Toluenesulfonamide ayinayo i-softening effect ye-plasticizers engamanzi, ayihambelani ne-polyvinyl chloride kunye ne-vinyl chloride copolymers, kwaye ngokuyinxenye ihambelana ne-cellulose acetate, i-cellulose acetate butyrate kunye ne-cellulose nitrate.
Indlela yokuvelisa kuqala yongeza inxalenye yamanzi e-HN3 kwi-reaction pot, yongeza i-p-toluenesulfonyl chloride ngelixa ivuselela, kwaye ubushushu buphakama ngokwendalo ukuya ngaphezu kwe-50 ° C. Emva kokuhla kweqondo lokushisa, amanzi asele e-ammonia ayongezwa. Ukusabela kwi-85 ~ 9Chemicalbook0℃ nge-0.5h. Ukusabela kuphela xa ixabiso le-pH lifikelela ku-8 ukuya ku-9. Pholisa ukuya kuma-20°C, hluza, kwaye uhlambe ikeyiki yokucoca ngamanzi ukuze ufumane imveliso ekrwada. Imveliso ke i-decolorized yi-carbon activated, inyibilika kwi-alkali, ihlulwe nge-asidi, ihluzwe kwaye yomiswe ukufumana imveliso.
