Ko te N,N-dimethyl-1,3-propanediamine (i muri nei ka kiia ko DMAPA) he diamine aliphatic iti me nga roopu amino tuatahi me nga roopu amino i roto i te ngota. He wai kore tae me te wai marama me te haukinia. Ka paowa i te hau, ka whakarewahia ki te wai me nga whakarewa pararopi. Ko tana tātai rāpoi ko C5H14N2 me tōna hanganga ko (CH3)2NCH2CH2CH2NH2.
Koia tetahi o nga momo tino nui o nga pūhui amine ngako me te takawaenga rawa pararopi. Kei te whakamahia nuitia i roto i nga matū o ia ra, pesticides, waikano, resins, me etahi atu I tenei wa, ko te nuinga o te DMAPA i Haina e whakamahia ana ki te whakarite i te betaine me te amidopropyldimethylamine, e whakamahia ana i roto i nga hua matū o ia ra, penei i te shampoo, te wai horoi, te waiu pepeke, te whāhauhau, te hopi wai me te horoi. I tua atu, ka whakamahia ano hoki te DMAPA hei whakakorikori polyurethane, hei kaiwhakaora kapia epoxy me te whakatere, me te hanga waikano.

Ko te huarahi whakahiato auraki o DMAPA ko: 1. Ma te whakamahi i te dimethylamine me te acrylonitrile hei rauemi mata, ka whiwhi te dimethylaminopropionitrile (DMAPN) ma te taapiri Michael. I roto i te tukanga o te whakaritenga ahumahi o DMAPN, e pā ana ki te 2% o te tapeke papatipu o rauemi mata te tikanga tāpiri ki te wai ki te whakatairanga i te tauhohenga tāpiri me te tango i te taikaha dimethylamine azeotropically; 2. Ko te DMAPN e whiwhi ana i te whakamarumaru i te taahiraa tuatahi ka whakawaiwai i raro i nga tikanga pehanga teitei. Whakaritenga o DMAPA

I te taahiraa tuarua o te hauwai hei whakarite i te DMAPA, ka puta he tauhohenga taha. Ko nga hua o tenei tauhohenga ko te amine tuarua bis-DMAPA me te amine tri-DMAPA tuatoru. I tenei wa, ko te hanga whare o DMAPA te nuinga o te tango i te tauhohenga kettle, a ko te whakakorikori hauwai he paura Raney nickel. Hei pehi i te hanganga o tenei hua-hua, he mea tika ki te taapiri i te 12%-16% o te papatipu whakakorikori o te wairewa wai aqueous alkali, te haukini wai ranei, te wairewa aqueous alkali me te haukini wai Ma te whakamahi ka nui te nui o te wai para me te wai para, he uaua ki te whakaheke me te tukatuka, ka piki ake te taumahatanga o muri i te tukatuka.
