Ko te p-Toluenesulfonamide he tino pai mo nga kirihou whakamaarama, he pai mo te kapia phenolic, melamine resin, urea-formaldehyde resin, polyamide me etahi atu kapia. Ma te iti o te whakakotahitanga ka taea te whakapai ake i te kaha o te mahi, te whakamaaramatanga o te rongoa, me te pai o te kanapa o te hua. Karekau te p-Toluenesulfonamide i te whakangawari o te whakakikorua wai, he hotokore ki te polyvinyl chloride me te vinyl chloride copolymers, a he mea hototahi ki te cellulose acetate, cellulose acetate butyrate me te cellulose nitrate.

Āhuatanga matū:

Kiriata kirikiri ma. Wairewa i roto i te waiwaro, kare e rewa i te wai me te etera.

tikanga whakaputa

Tuatahi, tāpirihia he wāhanga o te wai HN3 ki roto i te kōhua ​​tauhohenga, tāpirihia te p-toluenesulfonyl chloride i te wā e kōrorirori ana, ā, ka piki ake te pāmahana ki runga ake i te 50°C. I muri i te hekenga o te pāmahana, tāpirihia te toenga o te wai haukini. Tauhohe i te 85~90 ℃ Puka Matū mo te 0.5h. Ka mutu te tauhohenga ina tae te uara pH ki te 8 ki te 9. Whakamaohia ki te 20°C, tātari, ka horoi i te keke tātari ki te wai kia puta mai he hua maru. Ko te hua ka whakakorehia e te waro whakahohe, ka rewa ki te kawakore, ka wehea e te waikawa, ka tātarihia ka whakamaroke kia whiwhi ai i te hua.
