Lub cev thiab tshuaj muaj zog:N, N-dimethyl-p-toluidine yog cov kua tsis muaj xim lossis lub teeb daj oily nrog cov ntxhiab tsw ntawm cov qe lwj. Nws muaj qhov melting point ntawm 130.31 ° C, kub taw tes ntawm 211.5-212.5 ° C Chemicalbook, thiab lub ntiajteb txawj nqus ntawm 0.9287 ~ 0.9366g / mL ntawm chav tsev kub. Lub refractive index yog 1.5360 ~ 1.5470, insoluble nyob rau hauv dej, soluble nyob rau hauv ib co organic solvents, thiab decomposes thaum raug rau lub teeb.

Khoom piav qhia:N, N-dimethyl-p-toluidine yog soluble hauv qee cov kuab tshuaj organic thiab decomposes thaum raug lub teeb. Nws ua raws li photoinitiator zoo rau lub polymerization ntawm acrylonitrile (AN); nws kuj tseem siv tau los ua tus kheej kho hniav cov tais dej.

Daim ntawv thov:Raws li ib tug zoo photoinitiator rau lub polymerization ntawm acrylonitrile (AN), nws polymerization ceev yog proportional rau 1.62 lub zog ntawm AN concentration thiab 0.62 lub zog ntawm DMT concentration. Cov khoom no feem ntau yog siv los ua tus accelerator, thiab tseem tuaj yeem siv los ua cov khoom siv ntxiv rau kev sib txuas ntawm cov polyesters tsis zoo thiab cov nplaum.

Txoj kev Synthesis:Siv dimethyl sulfate ua tus neeg sawv cev methylating, N, N-dimethyl-p-toluidine tau tsim nyob rau hauv qhov kub thiab txias.

Kev siv:

1) Siv los ua tus kheej kho hniav cov tais dej

2) Ib qho tertiary amine uas tuaj yeem ua ke nrog phenylacetylene thiab benzamide nyob rau hauv lub xub ntiag ntawm di-tert-butyl peroxide rau hlau-catalyzed oxidation ntawm CC Chemicalbook los ua N,4-dimethyl-N-(3 -Phenylprop-2-ynyl) anizone thiab N-((methyl(p-tolyl)amino)methyl)benzamide.
