Diamines waa nooc muhiim ah oo kiimikooyin ah oo si weyn loogu isticmaalo walxo cayriin ah, dhexdhexaadin ama badeecooyin. Tusaale ahaan, diamines waa cutubyo muhiim ah oo qaab-dhismeed ah oo ku jira isku-darka polyamide iyo falgallada kale ee isku-dhafka ah ee isku-dhafka ah. N,N-dimethyl-Chemicalbook1,3-diaminopropane (DMAPA) waa dhexdhexaad muhiim ah, oo loo isticmaalo tusaale ahaan diyaarinta warshadaha ee saliidaha. Intaa waxaa dheer, DMAPA waxaa loo isticmaalaa sidii walxo cayriin ah oo loogu talagalay diyaarinta isku-dhafka unugyada lafteedana waa inay lahaataa sifooyin ka hortagga daxalka.

Isticmaalka:

Waxaa si ballaaran loogu isticmaalaa soo saarista agabka qurxinta ee ceeriin, sida palmitamide dimethylpropylamine, cocamidopropyl betaine, saliidda mink amidopropylamine, iwm.

Habka wax soo saarka:

Isticmaal dimethylaminopropionitrile [1738-25-6] sida walxo cayriin ah, hydrogenate iyo methanol marka uu jiro Ni-Al catalyst, ka dibna shaandhee oo milan si aad u hesho badeecad dhammaystiran oo 3-dimethylaminopropylamine ah. Nadiifnimada badeecada la helay waxay gaari kartaa in ka badan 99%, tan kasta oo badeecad ahna waxay isticmaashaa 1150kg oo dimethylaminopropionitrile ah.
