p-Toluenesulfonamide yog ib qho khoom siv yas zoo heev rau cov yas thermosetting, tsim nyog rau phenolic resin, melamine resin, urea-formaldehyde resin, polyamide thiab lwm yam resins. Kev sib xyaw me me tuaj yeem txhim kho kev ua haujlwm, ua kom tawv txawm tias, thiab muab cov khoom ci ntsa iab zoo. p-Toluenesulfonamide tsis muaj qhov cuam tshuam ua kom mos li cov kua yas, tsis sib haum nrog polyvinyl chloride thiab vinyl chloride copolymers, thiab ib feem sib haum nrog cellulose acetate, cellulose acetate butyrate thiab cellulose nitrate.

Cov khoom siv tshuaj lom neeg:

Cov siv lead ua dawb. Yaj hauv ethanol, tsis yaj hauv dej thiab ether.

txoj kev tsim khoom

Ua ntej, ntxiv ib feem ntawm cov dej HN3 rau hauv lub lauj kaub ua kom sib xyaw, ntxiv p-toluenesulfonyl chloride thaum do, thiab qhov kub yuav nce mus txog 50 ° C. Tom qab qhov kub poob qis, ntxiv cov dej ammonia seem. Ua kom sib xyaw ntawm 85 ~ 90 ℃ rau 0.5 teev. Qhov sib xyaw xaus thaum tus nqi pH ncav cuag 8 txog 9. Txias rau 20 ° C, lim, thiab ntxuav lub ncuav mog qab zib lim nrog dej kom tau txais cov khoom nyoos. Cov khoom tom qab ntawd raug tshem tawm xim los ntawm cov pa roj carbon activated, yaj hauv alkali, sib cais los ntawm acid, lim thiab ziab kom tau txais cov khoom.
