Diethanolamine (DEA) CAS No. 111-42-2
Hōʻike huahana
ʻO Diethanolamine, i hoʻopau pinepine ʻia e like me DEA a i ʻole DEOA, he mea hoʻohuihui mea ola me ke ʻano HN(CH2CH2OH)2. ʻO ka diethanolamine maʻemaʻe he paʻa keʻokeʻo ma ka lumi wela, akā ʻo kona makemake e komo i ka wai a me ka supercool ʻo ia ka mea e ʻike pinepine ʻia ma ke ʻano he wai kala ʻole. He polyfunctional ka Diethanolamine, he amine lua a he diol. E like me nā amine organik ʻē aʻe, hana ʻo diethanolamine ma ke ʻano nāwaliwali. E noʻonoʻo ana i ke ʻano hydrophilic o ka amine lua a me nā pūʻulu hydroxyl, hiki ke hoʻoheheʻe ʻia ʻo DEA i ka wai. ʻO nā Amides i hoʻomākaukau ʻia mai DEA he hydrophilic pinepine. I ka makahiki 2013, ua helu ʻia ka kemika e ka International Agency for Research on Cancer ma ke ʻano he "carcinogenic i ke kanaka".

Hoʻohana ʻia ʻo Diethanolamine i nā wai hana metala no ka ʻoki ʻana, ka hoʻopaʻa ʻana a me ka hana make-casting ma ke ʻano he mea hoʻopale corrosion. I ka hana ʻana i nā mea hoʻomaʻemaʻe, nā mea hoʻomaʻemaʻe, nā mea hoʻoheheʻe lole a me nā wai hana metala, hoʻohana ʻia ka diethanolamine no ka neutralization acid a me ka waiho ʻana o ka lepo. ʻO DEA kahi mea hoʻonāukiuki i ka ʻili i nā limahana i ʻike ʻia e ka ʻike ʻana i nā wai hana metala. Ua hōʻike kekahi haʻawina i ka DEA i loko o nā ʻiole pēpē i ka absorption o ka choline, ka mea e pono ai no ka ulu ʻana a me ka mālama ʻana i ka lolo; [8] akā naʻe, ua hoʻoholo ka noiʻi ʻana i nā kānaka i ka mālama ʻana i ka dermal no 1 mahina me kahi lotion ʻili i loaʻa i ka DEA ka hopena i DEA. nā pae i "ma lalo o kēlā mau manaʻo e pili ana i ka ulu ʻana o ka lolo i hoʻopilikia ʻia i ka ʻiole". nā loli maʻi a me ka histopathological, e hōʻike ana i ke koko haʻahaʻa, ka ate, ka puʻupaʻa a me ka testicular systemic toxicity.
ʻO ka DEA he mea hiki ke hoʻonāukiuki i kaʻili i nā limahana iʻikeʻia e kaʻikeʻana i nā wai hana metala. Ua hoʻoholo ʻo ia ʻo ka hoʻomaʻamaʻa dermal no 1 mahina me kahi lotion ʻili i loaʻa i ke kālepa i loaʻa ka DEA i hopena i nā pae DEA i "ma lalo o kēlā mau ʻike pili i ka ulu ʻana o ka lolo i ka ʻiole". Ma kahi noiʻi ʻiole o ka ʻike mau ʻana i ka DEA inhaled ma nā kiʻekiʻe kiʻekiʻe (ma luna o 150 mg/m3), ua ʻike ʻia ʻo DEA e hoʻoulu i nā loli kaumaha o ke kino a me ke kino, nā loli maʻi a me nā histopathological, e hōʻike ana i ke koko mālie, ke akepaʻa, ka ʻōpū a me ka testicular systemic toxicity. Ua ʻike ʻia kahi haʻawina i ka makahiki 2009 e loaʻa ana i ka DEA nā waiwai ʻawaʻawa, maʻi a me ka subchronic no nā ʻano wai.

ʻO ka maikaʻi o ka huahana, ka nui kūpono, ka hāʻawi maikaʻi ʻana, ke kūlana kiʻekiʻe o ka lawelawe He ʻoi aku ka maikaʻi ma mua o kahi amine like, ethanolamine, i hiki ke hoʻohana ʻia kahi kiʻekiʻe kiʻekiʻe no ka hiki ʻana o ka corrosion. ʻAe kēia i nā mea hoʻomaʻemaʻe e holoi i ka hydrogen sulfide ma kahi haʻahaʻa haʻahaʻa o ka amine me ka liʻiliʻi o ka hoʻohana ʻana i ka ikehu.
