Ko te N,N-dimethyl-1,3-propanediamine (e kiia nei i muri nei ko te DMAPA) he diamine aliphatic raro kei roto ngā rōpū amino tuatoru me ngā rōpū amino tuatahi i roto i te ngota. He wai mārama, kāore he tae, he kakara haukini. Ka paowa i te hau, ā, ka wairewa i roto i te wai me ngā whakarewa waro. Ko tōna tauira ngota ko C5H14N2, ā, ko tōna tauira hanganga ko (CH3)2NCH2CH2CH2NH2.
Ko tētahi o ngā momo matū amine ngako nui tēnei, ā, he takawaenga rauemi mata waro nui hoki. E whakamahia whānuitia ana i roto i ngā matū o ia rā, ngā patu pepeke, ngā tae, ngā kapia, me ētahi atu. I tēnei wā, ko te nuinga o te DMAPA i Haina e whakamahia ana hei hanga i te betaine me te amidopropyldimethylamine, e whakamahia ana i roto i ngā hua matū o ia rā pērā i te shampoo, te wai kaukau, te wai kaukau pēpi, te whakangawari tinana, te hopi wai me te hopi horoi. Hei tāpiri, ka whakamahia hoki te DMAPA hei whakakorikori polyurethane, hei kaiwhakaora kapia epoxy me te whakateretere, me te hanga tae.

Ko te huarahi matua o te hanga o te DMAPA ko: 1. Mā te whakamahi i te dimethylamine me te acrylonitrile hei rauemi mata, ka whiwhihia te dimethylaminopropionitrile (DMAPN) mā te tāpiritanga a Michael. I roto i te tukanga whakarite ahumahi o te DMAPN, tata ki te 2% o te papatipu katoa o ngā rauemi mata ka tāpirihia ki te wai hei whakatairanga i te tauhohenga tāpiri me te tango i te dimethylamine azeotropical nui; 2. Ko te DMAPN i whiwhihia mā te whakahoro i te taahiraa tuatahi ka whakahāngaihia ki te hauwai i raro i ngā tikanga pēhanga teitei. Te Whakaritenga o te DMAPA

I te taahiraa tuarua o te hauwai hei whakarite i te DMAPA, ka puta he tauhohenga taha. Ko ngā hua taha o tēnei tauhohenga ko te amine tuarua bis-DMAPA me te amine tuatoru tri-DMAPA. I tēnei wā, ko te nuinga o te wā e whakamahia ana e te hanga ā-rohe o te DMAPA te tauhohenga kettle, ā, ko te paura Raney nickel te mea e whakamahia ana hei whakakorikori hauwai. Hei pehi i te hanganga o tēnei hua taha, me tāpiri he 12%-16% o te taumaha whakakorikori o te wai waikawa waikawa, te haukini wai rānei, te wai waikawa waikawa waikawa me te haukini wai. Mā te whakamahi ka nui te wai para me te wai para, he uaua ki te pirau me te tukatuka, ka nui ake te taumaha o te tukatuka i muri.
