2,4,6-Trimethyl-1,3-phenylenediamine CAS: 3102-70-3

2,4,6-Trimethyl-1,3-phenylenediamine (TMPD) yog ib qho organic compound 2,4,6-Trimethyl-1,3-phenylenediamine (TMPD) muaj ntau yam kev siv thoob plaws ntau yam lag luam, feem ntau yog vim nws cov tshuaj tiv thaiv thiab cov yam ntxwv ntawm cov qauv. Ib qho ntawm nws cov kev siv tseem ceeb yog nyob rau hauv kev tsim cov xim thiab cov xim. TMPD ua haujlwm ua ib qho tseem ceeb hauv kev tsim cov xim azo, uas siv dav hauv cov ntaub, ntawv, thiab cov xim zaub mov. Cov azo compounds no qhia txog cov xim ci ntsa iab thiab kev ruaj khov tseem ceeb, ua rau lawv haum rau ntau yam kev siv hauv kev lag luam. Ntxiv rau nws lub luag haujlwm hauv kev tsim cov xim, TMPD kuj tseem siv ua tus neeg sawv cev kho hauv kev tsim cov epoxy resins. Nws cov haujlwm amine pab txhawb rau cov txheej txheem sib txuas, txhim kho cov khoom siv kho tshuab thiab kev tiv thaiv thermal ntawm cov khoom kawg. Qhov cwj pwm no ua rau TMPD muaj txiaj ntsig zoo hauv kev tsim cov txheej txheem ua haujlwm siab, cov nplaum, thiab cov ntaub ntawv sib xyaw. Ntxiv mus, TMPD tau pom daim ntawv thov hauv kev tshuaj xyuas tshuaj, tshwj xeeb tshaj yog ua cov tshuaj reagent hauv kev ntsuas xim. Nws siv tau los nrhiav qee cov hlau thiab lwm yam khoom sib xyaw vim nws muaj peev xwm tsim cov khoom sib xyaw uas ua rau muaj cov xim, ua rau kev tshuaj xyuas ntau ntxiv. Thaum kawg, kev tshawb fawb txuas ntxiv mus tab tom tshawb nrhiav kev siv cov TMPD derivatives hauv kev kho mob thiab cov khoom siv hluav taws xob organic, qhia txog qhov sib xyaw ua ke thiab qhov tseem ceeb hauv kev nce qib tam sim no thiab yav tom ntej. uas yog ib feem ntawm cov tshuaj aromatic amines. Nws yog tus cwj pwm los ntawm qhov muaj peb pawg methyl ntawm 2, 4, thiab 6 qhov chaw ntawm lub nplhaib aromatic, nrog rau ob pawg amino ntawm 1 thiab 3 qhov chaw. TMPD tshwm sim ua khoom khov kho nyob rau hauv cov xwm txheej txheem thiab feem ntau siv rau hauv ntau yam kev siv tshuaj vim nws cov khoom siv tshwj xeeb. Nws cov derivatives feem ntau raug tshawb nrhiav hauv cov tshuaj zas xim thiab cov ntaub ntawv tshawb fawb.
