N, N-dimethyl-1,3-propanediamine (hadda dambe loo yaqaan DMAPA) waa diamine hoose oo aliphatic ah oo leh labada kooxood ee sare iyo kuwa amino aasaasiga ah ee molecule. Waa dareere aan midab lahayn oo hufan oo leh ur ammonia ah. Waxay ku cabtaa hawada waxayna ku milmaysaa biyaha iyo dareerayaasha organic. Qaacidadeeda molecular waa C5H14N2 qaacidadeeduna waa (CH3)2NCH2CH2CH2NH2.
Waa mid ka mid ah noocyada muhiimka ah ee xeryahooda amine dufanka leh iyo dhexdhexaad walxo ceeriin ah oo muhiim ah. Waxaa si weyn loogu isticmaalaa kiimikooyinka maalinlaha ah, sunta cayayaanka, dheeha, resins, iwm. Waqtigan xaadirka ah, inta badan DMAPA ee Shiinaha waxaa inta badan loo isticmaalaa in lagu diyaariyo betaine iyo amidopropyldimethylamine, kuwaas oo loo isticmaalo alaabta maalinlaha ah ee kiimikooyinka sida shaambada, qubeyska, jelka qubeyska ilmaha, qaboojiyaha, saabuunta dareeraha ah iyo saabuunta. Intaa waxaa dheer, DMAPA waxaa sidoo kale loo isticmaalaa sidii kicinta poliurethane, wakiilka daweynta resin epoxy iyo dardargeliyaha, iyo soo saarista dheeha.

Dariiqa isku dhafka ah ee DMAPA waa: 1. Isticmaalka dimethylamine iyo acrylonitrile sida alaabta ceeriin, dimethylaminopropionitrile (DMAPN) waxaa lagu helaa isku darka Michael. Habka diyaarinta warshadaha ee DMAPN, qiyaastii 2% wadarta guud ee alaabta ceeriin ayaa guud ahaan lagu daraa biyaha si kor loogu qaado falcelinta dheeriga ah oo laga saaro dimethylamine xad-dhaaf ah azeotropically; 2. DMAPN-ka lagu helay distillation ee tallaabada ugu horreysa waxaa si firfircoon u hydrogenated hoos xaaladaha cadaadis sare. Diyaarinta DMAPA

Talaabada labaad ee hydrogenation-ka si loogu diyaariyo DMAPA, falcelin dhinac ah ayaa dhici doonta. Alaabooyinka ka soo baxay falcelintan ayaa ah inta badan aminiga sare ee amine bis-DMAPA iyo amine tri-DMAPA. Waqtigan xaadirka ah, wax soo saarka gudaha ee DMAPA wuxuu inta badan qaataa falcelinta kettle, iyo kicinta hydrogenation-ka waa Raney nikkel. Si loo xakameeyo sameynta badeecadan, waxaa lagama maarmaan ah in lagu daro 12% -16% mass kiciya ee xalalka alkali aqueous ama dareeraha ammonia, xalalka alkali aqueous iyo dareeraha ammonia Isticmaalku wuxuu soo saari doonaa qadar badan oo ah Biyaha wasakhda ah iyo dareeraha wasakhda ah, kuwaas oo ay adag tahay in la dhimo oo laga shaqeeyo, kordhinta culeyska ka dib habaynta.
