p-Toluenesulfonamide waa caag adag oo aad u fiican oo loogu talagalay balaastikada heerkulbeegga, oo ku habboon resin phenolic, resin melamine, resin urea-formaldehyde, polyamide iyo resins kale. Qadar yar oo isku dhafan ayaa wanaajin karta habsocodka, waxay ka dhigi kartaa daaweyn xitaa, waxayna siin kartaa alaabta dhalaalid wanaagsan. p-Toluenesulfonamide ma laha saamaynta jilicsanaanta caagagga dareeraha ah, kuma habboona polyvinyl chloride iyo vinyl chloride copolymers, waxayna qayb ahaan ku habboon tahay acetate cellulose, cellulose acetate butyrate iyo cellulose nitrate.

Sifooyinka kiimikaad:

Kiristaalo jilicsan oo cad. Ku milma ethanol, aan lagu milmin biyaha iyo etherka.

habka wax soo saarka

Marka hore, ku dar qayb ka mid ah biyaha HN3 digsiga falcelinta, ku dar p-toluenesulfonyl chloride markaad walaaqayso, heerkulku si dabiici ah wuxuu kor ugu kici doonaa 50 ° C. Kadib marka heerkulku hoos u dhaco, ku dar inta hartay biyaha ammonia. Ka fal celi 85~90℃Buugga Kiimikada 0.5h Dareen-celinta waxay dhammaanaysaa marka qiimaha pH uu gaaro 8 ilaa 9. Qabooji ilaa 20 ° C, shaandhee, oo ku dhaq keega shaandhada biyo si aad u hesho alaab cayriin. Alaabta ayaa markaa midabkeeda lagu beddelaa kaarboon firfircoon, lagu milmay alkali, oo lagu kala soocay aashitada, la sifeeyay oo la qalajiyey si loo helo badeecada.
