I-p-Toluenesulfonamide yiplastiki eqinileyo egqwesileyo kwiiplastiki ze-thermosetting, ifanelekile kwi-phenolic resin, i-melamine resin, i-urea-formaldehyde resin, i-polyamide kunye nezinye ii-resin. Umxube omncinci unokuphucula ukucutshungulwa, wenze ukucutshungulwa kube ngokulinganayo, kwaye unike imveliso ukukhanya okuhle. I-p-Toluenesulfonamide ayinayo impembelelo yokuthambisa yee-plasticizers ezingamanzi, ayihambelani nee-polyvinyl chloride kunye nee-vinyl chloride copolymers, kwaye ihambelana kancinci ne-cellulose acetate, i-cellulose acetate butyrate kunye ne-cellulose nitrate.

Iimpawu zekhemikhali:

Iikristale ezimhlophe eziqhekekileyo. Zinyibilika kwi-ethanol, azinyibiliki emanzini nakwi-ether.

indlela yemveliso

Okokuqala, yongeza inxalenye yamanzi e-HN3 kwimbiza yokusabela, yongeza i-p-toluenesulfonyl chloride ngelixa uvuselela, kwaye ubushushu buya kunyuka ngokwemvelo bufikelele kuma-50°C. Emva kokuba ubushushu buhlile, yongeza amanzi aseleyo e-ammonia. Yenza i-react kwi-85~90℃ Chemicalbook kangangeeyure eziyi-0.5. I-reaction iphela xa ixabiso le-pH lifikelela kwi-8 ukuya kwi-9. Pholisa ukuya kuma-20°C, hluza, kwaye uhlambe ikhekhe yokucoca ngamanzi ukuze ufumane imveliso ekrwada. Imveliso emva koko iyasuswa umbala yi-activated carbon, inyibilikiswe kwi-alkali, yahlulwe yi-asidi, ihluzwe kwaye yomiswe ukuze kufunyanwe imveliso.
