I-p-Toluenesulfonamide iyi-plasticizer eqinile kakhulu yamapulasitiki e-thermosetting, efanelekela i-phenolic resin, i-melamine resin, i-urea-formaldehyde resin, i-polyamide namanye ama-resin. Inani elincane lokuxuba lingathuthukisa ukucutshungulwa, lenze ukuqina kube ngokulinganayo, futhi linikeze umkhiqizo ukukhanya okuhle. I-p-Toluenesulfonamide ayinawo umphumela wokuthambisa wama-plasticizers aketshezi, ayihambisani nama-copolymer e-polyvinyl chloride kanye ne-vinyl chloride, futhi ihambisana kancane ne-cellulose acetate, i-cellulose acetate butyrate kanye ne-cellulose nitrate.

Izakhiwo zamakhemikhali:

Amakristalu amhlophe aqhekekile. Ancibilika ku-ethanol, awancibiliki emanzini nase-ether.

indlela yokukhiqiza

Okokuqala, engeza ingxenye yamanzi e-HN3 ebhodweni lokusabela, engeza i-p-toluenesulfonyl chloride ngenkathi uvuselela, futhi izinga lokushisa lizokhuphuka ngokwemvelo lifinyelele ngaphezu kwama-50°C. Ngemva kokwehla kwezinga lokushisa, engeza amanzi asele e-ammonia. Phendula ku-85~90℃ Chemicalbook amahora angu-0.5. Ukusabela kuphela lapho inani le-pH lifinyelela ku-8 kuya ku-9. Pholisa ku-20°C, hlunga, bese ugeza ikhekhe lokuhlunga ngamanzi ukuze uthole umkhiqizo ongahluziwe. Umkhiqizo ube usuguqulwa umbala yi-activated carbon, uncibilikiswe ku-alkali, uhlukaniswe yi-asidi, uhlungwe bese womiswa ukuze uthole umkhiqizo.
