Izakhiwo ze-N,N-Dimethyl-p-toluidine, ukusetshenziswa kanye nenqubo yokukhiqiza izakhiwo ze-physicochemical

I-N,N-dimethyl-p-toluidine iwuketshezi olunamafutha angenambala noma oluphuzi ngokukhanyayo olunephunga leqanda elibolile, indawo yokuncibilika 130.31℃, iphuzu elibilisayo 211.5-212.5℃, isisindo 0.9287-0.9366g/mL ekamelweni lokushisa, inkomba ye-refractive 1.5360-1.5470, engancibiliki emanzini, e-some-organic solvents, aboliswa ukukhanya.Isetshenziswa njenge-photoinitiator esebenzayo ye-polymerization ye-acrylonitrile (AN), futhi isivinini sayo se-polymerization silingana ne-1.62nd yokugxilisa ingqondo ye-AN kanye ne-0.62nd yokugxilisa ingqondo ye-DMT.Umkhiqizo uvame ukusetshenziswa njenge-accelerator futhi, ngaphezu kwalokho, njengesengezo ekuhlanganisweni kwama-polyester angasetshenzisiwe kanye nama-bonding agents.Indlela yokwenziwa: I-N,N-dimethyl-p-toluidine ihlanganiswa ngokusebenzisa i-dimethyl sulfate njenge-ejenti ye-methylating ekushiseni okuphansi kanye nokucindezela komkhathi.I-N,4-dimethyl-N-(3-phenylprop-2-ynyl)benzylamine kanye ne-N-(methyl(p-tolyl)amino)methyl)benzamide ingakhiwa ngokuhlangana kwe-iron-catalyzed oxidative CC ne-phenacetylene kanye ne-benzamide lapho kukhona. i-di-tert-butyl peroxide, ngokulandelana.
