p-Toluenesulfonamide yog ib qho khoom siv zoo heev rau cov yas thermosetting, haum rau phenolic resin, melamine resin, urea-formaldehyde resin, polyamide thiab lwm yam resins. Ib qho me me ntawm kev sib xyaw tuaj yeem txhim kho kev ua tau zoo, ua kom zoo dua qub, thiab muab cov khoom ua kom zoo nkauj. p-Toluenesulfonamide tsis muaj cov nyhuv softening ntawm cov kua plasticizers, yog incompatible nrog polyvinyl chloride thiab vinyl chloride copolymers, thiab yog ib feem ntawm cellulose acetate, cellulose acetate butyrate thiab cellulose nitrate.

Chemical Properties:

Dawb flaky crystals. Soluble hauv ethanol, insoluble hauv dej thiab ether.

txoj kev tsim khoom

Ua ntej, ntxiv ib feem ntawm HN3 dej rau hauv cov tshuaj tiv thaiv lub lauj kaub, ntxiv p-toluenesulfonyl chloride thaum nplawm, thiab qhov kub thiab txias yuav nce siab tshaj 50 ° C. Tom qab kub poob, ntxiv cov dej ammonia ntxiv. React ntawm 85 ~ 90 ℃ Chemicalbook rau 0.5h. Cov tshuaj tiv thaiv xaus thaum tus nqi pH nce mus txog 8 txog 9. Txias rau 20 ° C, lim, thiab ntxuav lub ncuav mog qab zib lim dej kom tau cov khoom nyoos. Cov khoom no ces decolorized los ntawm activated carbon, yaj nyob rau hauv alkali, sib cais los ntawm acid, lim thiab qhuav kom tau cov khoom.
