N, N-dimethyl-1,3-propanediamine (eo ka mor'a moo e bitsoang DMPA) ke diamine e tlase ea aliphatic e nang le lihlopha tsa amino tse phahameng le tsa mantlha ka har'a molek'hule. Ke mokelikeli o se nang 'mala le o bonaletsang o nang le monko oa ammonia. E tsuba moeeng 'me e qhibiliha ka metsing le ka har'a metsoako ea tlhaho. Foromo ea eona ea molek'hule ke C5H14N2 mme mokhoa oa eona oa sebopeho ke (CH3)2NCH2CH2CH2NH2.
Ke e 'ngoe ea mefuta ea bohlokoa ea metsoako ea amine e nang le mafura le ntho ea bohlokoa ea organic e tala. E sebelisoa haholo lik'hemik'hale tsa letsatsi le letsatsi, chefo e bolaeang likokoanyana, lidae, li-resin, joalo-joalo. Hona joale, boholo ba DMPA Chaena bo sebelisoa haholo-holo ho lokisetsa betaine le amidopropyldimethylamine, tse sebelisoang lihlahisoa tsa lik'hemik'hale tsa letsatsi le letsatsi tse kang shampoo, gel ea ho hlapa, gel ea bana, conditioner, sesepa sa metsi le sesepa. Ntle le moo, DMPA e boetse e sebelisoa e le sesebelisoa sa polyurethane, epoxy resin e phekolang le accelerator, le tlhahisong ea lidae.
Tsela e tloaelehileng ea ho kopanya ea DMPA ke: 1. Ho sebelisa dimethylamine le acrylonitrile e le lisebelisoa tse tala, dimethylaminopropionitrile (DMAPN) e fumanoa ka ho eketsa Michael. Ts'ebetsong ea ho lokisoa ha indasteri ea DMAPN, hoo e ka bang 2% ea kakaretso ea boima ba lihlahisoa tse tala hangata e kenngoa metsing ho ntšetsa pele karabelo ea tlatsetso le ho tlosa dimethylamine e feteletseng azeotropically; 2. DMAPN e fumanoang ka distillation mohato oa pele ke catalytically hydrogenated tlas'a maemo a phahameng a khatello. Tokisetso ea DMPA
Mohato oa bobeli oa hydrogenation ho lokisetsa DMPA, karabelo ea lehlakore e tla etsahala. Lihlahisoa tsa karabelo ena haholo-holo ke amine bis-DMPA ea bobeli le tertiary amine tri-DMPA. Hona joale, tlhahiso ea malapeng ea DMPA haholo-holo e amohela kettle reaction, 'me motsoako oa hydrogenation ke phofo ea Raney nickel. E le ho hatella sebopeho sa sehlahisoa sena, ho hlokahala ho eketsa 12% -16% ea catalyst mass ea caustic alkali aqueous solution kapa liquid ammonia, caustic alkali aqueous solution le liquid ammonia Tšebeliso e tla hlahisa palo e kholo ea metsi a litšila le mokelikeli o litšila, oo ho leng thata ho o theola le ho o sebetsa, ho eketsa moroalo oa ts'ebetso ea morao-rao.
