incazelo emfushane:

I-p-Toluenesulfonamide, eyaziwa nangokuthi i-4-toluenesulfonamide, p-sulfonamide, toluene-4-sulfonamide, toluenesulfonamide, p-sulfamoyltoluene, ikhekheba elimhlophe noma i-Chemicalbook crystal yeqabunga, esetshenziselwa ukuhlanganisa i-chloramine-T ne-Chloramphenicol, odayi be-fluorescent, ukukhiqizwa kwe-plasticizer. , ama-synthetic resins, ama-coatings, ama-disinfectants kanye nezikhanyisi zokucubungula izinkuni, njll.
I-p-Toluenesulfonamide iyi-plasticizer eqinile ehle kakhulu yamapulasitiki e-thermosetting, elungele i-phenolic resin, i-melamine resin, i-urea-formaldehyde resin, i-polyamide nezinye izinhlaka. Inani elincane lokuxuba lingathuthukisa ukucutshungulwa, lenze ukuphulukiswa okulinganayo, futhi linikeze umkhiqizo isicwebezelisi esihle. I-p-Toluenesulfonamide ayinawo umphumela wokuthambisa wamapulasitiki oketshezi, ayihambisani ne-polyvinyl chloride ne-vinyl chloride copolymers, futhi ihambisana ngokwengxenye ne-cellulose acetate, i-cellulose acetate butyrate ne-cellulose nitrate.
Indlela yokukhiqiza iqala yengeza ingxenye yamanzi e-HN3 embizeni yokusabela, yengeza i-p-toluenesulfonyl chloride ngenkathi inyakaza, futhi izinga lokushisa likhuphuka ngokwemvelo libe ngaphezu kuka-50°C. Ngemva kokwehla kwezinga lokushisa, amanzi e-ammonia asele ayengeziwe. Sabela ku-85~9Chemicalbook0℃ ngo-0.5h. Ukusabela kugcina lapho inani le-pH lifinyelela ku-8 kuya ku-9. Pholisa ukuya ku-20°C, hlunga, bese ugeza ikhekhe lokuhlunga ngamanzi ukuze uthole umkhiqizo ongahluziwe. Umkhiqizo ube usukhishwa umbala ngekhabhoni ecushiwe, incibilikiswe ku-alkali, ihlukaniswe yi-asidi, ihlungwe futhi yomiswe ukuze kutholwe umkhiqizo.
