ʻO Triethanolamine Ua ʻike ʻia ʻo Triethanolamine ʻo ia hoʻi ʻo ʻekolu mau kumu amine hoʻohui a me triethanol. He wai ʻaila kala ʻole ia me ke ʻala o ka ammonia. Hoʻopili maʻalahi ia i ka wai a lilo i ʻeleʻele ke hōʻike ʻia i ka lewa a i ʻole i ka mālamalama. Lilo ia i kristal cubic melemele ʻole a i ʻole melemele māmā i ka mahana haʻahaʻa.

Nā waiwai kemika:

He wai ʻole kona kala, moakaka a mānoanoa hoʻi i ka mahana o ka lumi. He hygroscopic, he ʻala ammonia, he alkaline, a he mea hoʻonāukiuki. ʻO ke kiko heheʻe he 21.2 ℃, ʻo ke kiko paila he 360 ​​℃, ʻo ke kiko flash he 193 ℃, ʻo ka Chemicalbook relative density (d420) he 1.1242, a ʻo ka refractive index (nD20) he 1.4852. Hiki ke hui pū ʻia i ka wai, ka ethanol a me ka acetone, hoʻoheheʻe iki ʻia i ka ether, benzene a me ke carbon tetrachloride.

Pahuhopu:

Hoʻohana ʻia ma ke ʻano he wai maʻemaʻe no ka wehe ʻana i ke kalapona ʻokikene a i ʻole ka hydrogen sulfide mai ke kinoea. Hoʻohana nui ʻia nā Esters i hana ʻia ma waena o ka triethanolamine a me nā waikawa momona kiʻekiʻe e like me nā detergents, emulsifiers, humectants a me nā lubricants, a hoʻohana ʻia hoʻi i ka hoʻomākaukau ʻana i nā balms cosmetic. Hoʻohana ʻia ʻo Triethanolamine ma ke ʻano he mea mālama, mea pale wai, reagent analytical, a me ka solvent. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻoulu i ka polymerization o ka nitrile rubber, a hiki ke hoʻohana ʻia ma ke ʻano he emulsifier a me ka stabilizer no nā aila a me nā waxes, a me kahi mea palupalu no nā textiles ma lalo o nā kūlana acidic. ʻO ia kekahi o nā ʻāpana o ka ʻaila milo no ka polyester a me nā fibers synthetic ʻē aʻe.

ʻano hana

ʻO ia ke hānai ʻana i ka ethylene oxide a me ka wai ammonia i loko o ka reactor, a hana i kahi hopena condensation ma kahi mahana hopena o 30-40°C a me ke kaomi hopena o 70.9-304kPa e hana i kahi hopena hui o mono-, di-, a me triethanolamine, kahi i hoʻomehana ʻia ma 90-120°C. Ma hope o ka dehydration a me ka noʻonoʻo ʻana, hoʻouna ʻia i ʻekolu mau hale kiaʻi distillation Chemicalbook vacuum no ka distillation vacuum. Hoʻopaʻa ʻia nā ʻāpana e like me nā kiko paila like ʻole e loaʻa ai nā huahana i hoʻopau ʻia o monoethanolamine, diethanolamine a me triethanolamine me ka maʻemaʻe o 99%. I ka wā o ke kaʻina hana, inā hoʻonui ʻia ka hapa o ka ethylene oxide, e hoʻonui ʻia ka lakio hana o di- a me triethanolamine, hiki ke hoʻonui i ka hua o di- a me triethanolamine.
