N,N-dimethyl-1,3-propanediamine (eo ho tloha mona e tla bitsoa DMAPA) ke diamine e tlase ea aliphatic e nang le lihlopha tsa amino tse tharo le tse ka sehloohong molek'huleng. Ke mokelikeli o se nang 'mala le o bonaletsang o nang le monko oa ammonia. O tsuba moeeng 'me o qhibiliha ka metsing le li-solvents tsa tlhaho. Foromo ea eona ea limolek'hule ke C5H14N2 'me foromo ea eona ea sebopeho ke (CH3)2NCH2CH2CH2NH2.
Ke e 'ngoe ea mefuta ea bohlokoa ea metsoako ea mafura a amine le karolo ea bohlokoa ea lintho tse tala tsa tlhaho. E sebelisoa haholo lik'hemik'haleng tsa letsatsi le letsatsi, chefo e bolaeang likokoanyana, lidae, li-resin, jj. Hona joale, boholo ba DMAPA Chaena bo sebelisoa haholo ho lokisa betaine le amidopropyldimethylamine, tse sebelisoang lihlahisoa tsa lik'hemik'hale tsa letsatsi le letsatsi tse kang shampoo, shaoara ea shaoara, gel ea shaoara ea bana, conditioner, sesepa sa metsi le sesepa sa ho hlatsoa. ​​Ho phaella moo, DMAPA e boetse e sebelisoa e le sesebelisoa sa ho baka polyurethane, sesebelisoa sa ho phekola resin ea epoxy le accelerator, le tlhahisong ea lidae.

Tsela e ka sehloohong ea ho kopanya DMAPA ke: 1. Ho sebelisoa dimethylamine le acrylonitrile e le thepa e tala, dimethylaminopropionitrile (DMAPN) e fumanoa ka ho eketsa Michael. Nakong ea ho lokisa DMAPN indastering, hoo e ka bang 2% ea boima bohle ba thepa e tala hangata e eketsoa metsing ho khothaletsa karabelo ea ho eketsa le ho tlosa dimethylamine e feteletseng azeotropically; 2. DMAPN e fumanoeng ka ho qhibilihisa mohatong oa pele e hydrogenated ka mokhoa oa catalytically tlas'a maemo a khatello e phahameng. Ho lokisa DMAPA

Mohatong oa bobeli oa hydrogenation ho lokisa DMAPA, ho tla hlaha karabelo e ka thoko. Lihlahisoa tse tsoang ho karabelo ena haholo-holo ke amine ea bobeli bis-DMAPA le tertiary amine tri-DMAPA. Hona joale, tlhahiso ea lapeng ea DMAPA e amohela haholo-holo karabelo ea kettle, 'me catalyst ea hydrogenation ke phofo ea Raney nickel. E le ho thibela ho thehoa ha sehlahisoa sena se tsoang ho sona, ho hlokahala ho eketsa 12%-16% ea boima ba catalyst ba tharollo ea metsi ea caustic alkali kapa ammonia e metsi, tharollo ea metsi ea caustic alkali le ammonia e metsi. Tšebeliso e tla hlahisa metsi a mangata a litšila le mokelikeli o litšila, o thata ho o senya le ho o sebetsana, o eketsa moroalo oa kamora ts'ebetso.
