P-Toluenesulfonamide ndi pulasitiki wabwino kwambiri wopangira thermosetting plastics, woyenera phenolic resin, melamine resin, urea-formaldehyde resin, polyamide ndi ma resin ena. Kusakaniza pang'ono kungathandize kukonza zinthu, kupangitsa kuti zikhale zofanana, ndikupatsa mankhwalawa kuwala bwino. P-Toluenesulfonamide ilibe mphamvu yofewa ngati ma plasticizer amadzimadzi, sigwirizana ndi polyvinyl chloride ndi vinyl chloride copolymers, ndipo imagwirizana pang'ono ndi cellulose acetate, cellulose acetate butyrate ndi cellulose nitrate.

Kapangidwe ka mankhwala:

Makristalo oyera opindika. Amasungunuka mu ethanol, osasungunuka m'madzi ndi ether.

njira yopangira

Choyamba, onjezerani madzi a HN3 mumphika wothira, onjezerani p-toluenesulfonyl chloride mukusakaniza, ndipo kutentha kudzakwera mwachibadwa kufika pa 50°C. Kutentha kukatsika, onjezerani madzi otsala a ammonia. Chitanipo kanthu pa 85~90℃ Chemicalbook kwa maola 0.5. Kuyankha kumatha pamene pH ifika pa 8 mpaka 9. Ziziritseni mpaka 20°C, sefani, ndikutsuka keke yosefera ndi madzi kuti mupeze chinthu chosaphikidwa. Kenako chinthucho chimasinthidwa mtundu ndi mpweya woyambitsa, kusungunuka mu alkali, kulekanitsidwa ndi asidi, kusefedwa ndikuumitsidwa kuti mupeze chinthucho.
