N, N-Dimethyl-p-toluidine CAS:99-97-8 ib

N, N-Dimethyl-p-toluidine zog, siv thiab ntau lawm txheej txheem physicochemical zog

N, N-dimethyl-p-toluidine yog xim tsis muaj xim lossis lub teeb daj oily kua nrog tsw ntawm qe lwj, melting point 130.31℃, kub point 211.5-212.5℃, hnyav 0.9287-0.9366g / mL ntawm chav tsev kub, refractive index 1.5360-1.5470, insoluble hauv dej, soluble hauv some organic solvents, decomposed los ntawm lub teeb. Nws yog siv los ua ib qho zoo photoinitiator rau polymerization ntawm acrylonitrile (AN), thiab nws cov polymerization ceev yog proportional rau 1.62nd ntawm AN concentration thiab 0.62nd ntawm DMT concentration. Cov khoom no feem ntau yog siv los ua ib qho accelerator thiab, ntxiv rau, ua ib qho ntxiv hauv kev sib txuas ntawm cov polyesters tsis zoo thiab hauv cov khoom sib txuas. Synthesis method: N, N-dimethyl-p-toluidine yog synthesized los ntawm kev siv dimethyl sulfate ua tus neeg sawv cev methylating ntawm qhov kub thiab txias atmospheric. N,4-dimethyl-N-(3-phenylprop-2-ynyl) benzylamine thiab N-(methyl(p-tolyl)amino)methyl)benzamide tuaj yeem tsim los ntawm hlau-catalyzed oxidative CC coupling nrog phenacetylene thiab benzamide nyob rau hauv lub xub ntiag. ntawm di-tert-butyl peroxide, raws li.
