He papa koʻikoʻi nā diamines o nā kemika i hoʻohana nui ʻia ma ke ʻano he mea maka, nā mea waena a i ʻole nā ​​​​huahana. No ka laʻana, he mau ʻāpana kūkulu koʻikoʻi nā diamines i ka synthesis o ka polyamide a me nā hopena polymerization condensation ʻē aʻe. ʻO N,N-dimethyl-Chemicalbook1,3-diaminopropane (DMAPA) kahi mea waena koʻikoʻi, i hoʻohana ʻia no ka laʻana i ka hoʻomākaukau ʻoihana o nā lubricants. Eia kekahi, hoʻohana ʻia ka DMAPA ma ke ʻano he mea maka no ka hoʻomākaukau ʻana i nā coagulants a pono iā ia iho nā waiwai Anti-corrosion.

Nā Waiwai Kemika:

Wai ʻole kala a moakāka. Hiki ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe organik.

ʻO ke ʻano molekole C5H14N2

Kaumaha molekiola 102.18

EINECS Helu 203-680-9

Kiko heheʻe -60°C

Ka paila ʻana 133°C (lit.)

Ka nui o ka paʻa 0.812g/mL ma 25°C (mālamalama ʻia)

ʻIneki refractive n20/D1.435 (lit.)

Hoʻohana:

Hoʻohana nui ʻia i ka hana ʻana i nā mea maka maka, e like me ka palmitamide dimethylpropylamine, cocamidopropyl betaine, mink aila amidopropylamine, etc.

ʻAno hana:

E hoʻohana i ka dimethylaminopropionitrile [1738-25-6] ma ke ʻano he mea maka, hydrogenate a me methanol i ke alo o ka mea hoʻoulu Ni-Al, a laila kānana a hoʻoheheʻe e loaʻa ai ka huahana i hoʻopau ʻia ʻo 3-dimethylaminopropylamine. Hiki i ka maʻemaʻe o ka huahana i loaʻa ke hiki aku ma mua o 99%, a ʻo kēlā me kēia tona o ka huahana e hoʻopau i 1150kg o dimethylaminopropionitrile.
