N,N-Dimethyl-p-toluidine CAS：99-97-8

Cov khoom ntawm N,N-Dimethyl-p-toluidine, kev siv thiab cov txheej txheem tsim khoom ntawm cov khoom siv physicochemical

N,N-dimethyl-p-toluidine yog ib qho kua roj tsis muaj xim lossis daj daj uas muaj ntxhiab tsw ntawm qe lwj, lub ntsiab lus yaj 130.31℃, kub taw tes 211.5-212.5℃, qhov hnyav 0.9287-0.9366g / mL ntawm chav tsev kub, refractive index 1.5360-1.5470, insoluble hauv dej, soluble hauv somCov kuab tshuaj organic, uas lwj los ntawm lub teeb. Nws yog siv los ua tus photoinitiator zoo rau kev polymerization ntawm acrylonitrile (AN), thiab nws qhov ceev polymerization yog proportional rau 1.62nd ntawm AN concentration thiab 0.62nd ntawm DMT concentration. Cov khoom no feem ntau siv los ua tus accelerator thiab, ntxiv rau, ua ib qho additive hauv kev tsim cov polyesters unsaturated thiab hauv cov neeg sawv cev bonding. Txoj kev synthesis: N, N-dimethyl-p-toluidine yog synthesized los ntawm kev siv dimethyl sulfate ua tus neeg sawv cev methylating ntawm qhov kub qis thiab atmospheric siab. 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, feem.
