N,N-dimethyl-1,3-propanediamine (inonzi DMAPA) idiamine yakaderera ine maamino akawanda uye epakutanga mumorekuru. Imvura isina ruvara uye inoonekera ine hwema hweammonia. Inoputa mumhepo uye inonyungudika mumvura uye mune zvinonyungudutsa. Fomura yayo yemamorekuru iC5H14N2 uye fomura yayo yemaumbirwo i (CH3)2NCH2CH2CH2NH2.
Ndiyo imwe yemhando dzakakosha dzemafuta amine compounds uye chinhu chakakosha che organic raw material. Inoshandiswa zvakanyanya mumakemikari ezuva nezuva, mishonga yezvipembenene, madhayi, maresini, nezvimwewo. Parizvino, DMAPA yakawanda muChina inonyanya kushandiswa kugadzira betaine uye amidopropyldimethylamine, iyo inoshandiswa muzvigadzirwa zvemakemikari zvezuva nezuva zvakaita seshampoo, shower gel, baby shower gel, conditioner, liquid sipo uye sipo. Pamusoro pezvo, DMAPA inoshandiswawo se polyurethane catalyst, epoxy resin curing agent uye accelerator, uye mukugadzira madhayi.

Nzira huru yekugadzira DMAPA ndeiyi: 1. Kushandisa dimethylamine neacrylonitrile sezvinhu zvakagadziriswa, dimethylaminopropionitrile (DMAPN) inowanikwa kuburikidza nekuwedzera kwaMichael. Mukugadzirwa kweDMAPN mumaindasitiri, inenge 2% yehuwandu hwese hwezvinhu zvakagadziriswa inowanzowedzerwa mumvura kukurudzira kuwedzera uye kubvisa dimethylamine yakawandisa azeotropically; 2. DMAPN inowanikwa nekudistilla muchikamu chekutanga inogadziriswa hydrogen pasi pemamiriro ekumanikidzwa kwakanyanya. Kugadzirira DMAPA

Mudanho rechipiri rehydrogenation yekugadzirira DMAPA, pane reaction yedivi rinoitika. Zvibereko zve reaction iyi zvinonyanya kuve secondary amine bis-DMAPA uye tertiary amine tri-DMAPA. Parizvino, kugadzirwa kweDMAPA mudzimba kunonyanya kushandisa kettle reaction, uye hydrogenation catalyst ihupfu hweRaney nickel. Kuti kudzvinyirire kuumbwa kweiyi by-product, zvakakosha kuwedzera 12%-16% ye catalyst mass ye caustic alkali aqueous solution kana liquid ammonia, caustic alkali aqueous solution uye liquid ammonia. Kushandiswa kuchaburitsa huwandu hwakawanda hwemvura yakasviba uye marara emvura, izvo zvakaoma kusvibisa nekugadzirisa, zvichiwedzera mutoro wekugadzirisa mushure mekugadzirisa.
