N,N-Dimethyl-p-toluidine ngā āhuatanga, ngā whakamahinga me te tukanga whakaputa āhuatanga ahupūngao

Ko te N,N-dimethyl-p-toluidine he wai hinuhinu kore tae, kowhai marama ranei me te kakara o te hua manu pirau, ira whakarewa 130.31℃, ira kohua 211.5-212.5℃, te taumaha 0.9287-0.9366g/mL i te pāmahana rūma, te taupū whakaata 1.5360-1.5470, karekau ki te wai, ka rewa ki te some wairewa pararopi, kua pirau e te marama. Ka whakamahia hei photoinitiator whai hua mo te polymerization o te acrylonitrile (AN), a ko tona tere polymerization he rite ki te 1.62nd o te kukū AN me te 0.62nd o te DMT. Ka whakamahia te hua hei whakaterenga, hei taapiri, hei taapiri mo te whakahiato o nga polyesters haunga me nga hononga honohono. Tikanga whakahiato: N,N-dimethyl-p-toluidine ka whakahiatohia ma te whakamahi i te dimethyl sulfate hei kaihoko methylating i te iti o te pāmahana me te pehanga hau. N,4-dimethyl-N-(3-phenylprop-2-ynyl)benzylamine me N-(methyl(p-tolyl)amino)methyl)benzamide ka taea te hanga e te rino-catalyzed oxidative CC hono ki te phenacetylene me te benzamide i mua. o te di-tert-butyl peroxide, ia.
