ʻO Diethylenetriamine CAS 111-40-0

He wai ʻaila ʻole kala a melemele māmā paha me ke ʻala ammonia a me ka huhū. ʻO ka nui o ka lapalapa ʻana he 0.9542 (20 ℃), ʻo ke kiko heheʻe he -39 ℃, ʻo ke kiko paila he 207 ℃, a ʻo ke kiko lapalapa he 94 ℃. Hoʻoheheʻe ʻia i ka wai, ka ethanol a me ka acetone, ʻaʻole hoʻoheheʻe ʻia i ka ether. He alkaline loa ia a pane me ka waikawa e hana i nā paʻakai like. Hoʻokumu maʻalahi i nā hui me nā paʻakai metala kaumaha. He hygroscopic loa ia a hoʻomoʻa maʻalahi i ka makū a me ke kalapona dioxide i ka lewa, e hana ana i ka uahi keʻokeʻo i ka lewa. He mea ʻino loa ia a he mea ʻino i ke keleawe a me nā mea hao keleawe. He mea ʻino loa a hoʻonāukiuki i ka ʻili, nā membrane mucous a me ke ala hanu.

[Hoʻohana]

Hoʻohana ʻia ma ke ʻano he mau waena synthesis organik a me nā mea hoʻoheheʻe. Hoʻohana ʻia i ka hana ʻana o nā resins polyamide, nā resins hoʻololi ion, nā surfactants, nā mea hoʻohui lubricant, nā mea hoʻopau lole a me nā kemika kiʻi. Hoʻohana pinepine ʻia hoʻi ia ma ke ʻano he mea hoʻōla mahana lumi no ka epoxy resin, ka mea hoʻomaʻemaʻe kinoea, ka mea hoʻoikaika pepa, ka mea hoʻopili aminocarboxylic, ka mea hoʻohui metala, ka mea hoʻomālamalama, a pēlā aku.

[ʻAno hoʻomākaukau pōkole] Hoʻomākaukau ʻia ia ma ka hana ʻana i ka amination wela a me nā hopena ammonolysis ma waena o dichloroethane a me ammonia ma 100 ~ 150 ℃ a me 4MPa, e hoʻopau ana me ka alkali a laila e hoʻoheheʻe ʻia. Penei ke ʻano o ka hopena:

[Palekana a me ka Hoʻomalu]

Hoʻopaʻa ʻia i loko o nā pahu polyethylene plastic me ka paona o 50kg no ka pahu; hiki ke hoʻopaʻa ʻia i loko o nā pahu hao me ka paona o 200kg no ka pahu; i nā liʻiliʻi, hiki ke hoʻopaʻa ʻia i loko o nā ʻōmole aniani 0.5kg a i ʻole 1kg. E mālama i kahi anuanu a me ka ea, a mai noho pū a lawe pū me nā waikawa.

He wai ʻawaʻawa alkaline ikaika kēia huahana. Inā pili ka ʻili, e holoi koke me ka wai a i ʻole ka wai boric acid e hoʻoheheʻe ʻia.
