p-Toluenesulfonamide ipurasitiki yakasimba yakasimba ye thermosetting mapurasitiki, yakakodzera phenolic resin, melamine resin, urea-formaldehyde resin, polyamide uye mamwe marekeni. Huwandu hudiki hwekusanganisa hunogona kuvandudza mashandiro, kuita kurapa kunyangwe, uye kupa chigadzirwa kupenya kwakanaka. p-Toluenesulfonamide haina kupfava kwemvura yeplasticizers, haienderani nepolyvinyl chloride uye vinyl chloride copolymers, uye inopindirana ne cellulose acetate, cellulose acetate butyrate uye cellulose nitrate.

Chemical properties:

Makristasi machena. Soluble mu ethanol, isinganyunguriki mumvura uye ether.

kugadzira nzira

Chekutanga, wedzera chikamu chemvura yeHN3 muhari yekupindura, wedzera p-toluenesulfonyl chloride uchikurunga, uye tembiricha inongokwira kusvika pamusoro pe50°C. Mushure mekudonha kwekushisa, wedzera mvura yakasara yeammonia. React pa85 ~ 90 ℃Chemicalbook ye0.5h. Mhedzisiro yacho inopera kana pH yasvika pa8 kusvika 9. Kutonhodza kusvika pa20°C, sefa, uye geza keke resefa nemvura kuti uwane crude product. Chigadzirwa chacho chinozoitwa decolorized ne activated carbon, yakanyungudutswa mualkali, yakaparadzaniswa neasidhi, yakasefa uye yakaomeswa kuti iwane chigadzirwa.
