ʻO ka Diamine kahi papa koʻikoʻi o nā mea kemika i hoʻohana nui ʻia e like me nā mea maka, waena a huahana paha. No ka laʻana, ʻo diamine kahi ʻāpana hana koʻikoʻi i ka synthesis o ka polyamide a me nā hopena polymerization condensation. ʻO N,N-dimethyl-1Chemicalbook,3-diaminopropane (DMAPA) kahi mea koʻikoʻi waena, hoʻohana ʻia no ka laʻana i ka hoʻomākaukau ʻana i ka ʻoihana o nā lubricants. Eia kekahi, hoʻohana ʻia ʻo DMAPA ma ke ʻano he mea maka no ka hoʻomākaukau ʻana i nā coagulants a pono iā ia iho nā waiwai Anti-corrosion.
He wai aniani ʻole waihoʻoluʻu. Hiki ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe organik. Hoʻohana nui ʻia i ka hana ʻana i nā mea waiwai, e like me ka palmitamide dimethylpropylamine, cocamidopropyl betaine, mink oil amidopropylamine, etc.
Ke hoʻohana nei i ka dimethylaminopropionitrile [1738-25-6] ma ke ʻano he mea maka, hoʻohui ʻia ka hydrogenation a me ka methanol i mua o ka catalyst Ni-Al, a laila kānana a hoʻoheheʻe ʻia no ka loaʻa ʻana o ka huahana pau o 3-dimethylaminopropylamine. ʻO ka maʻemaʻe o ka huahana i loaʻa hiki ke piʻi ma mua o 99%, a ʻo kēlā me kēia ton o ka huahana e hoʻopau i ka 1150kg o dimethylaminopropionitrile.
