1. He aha ka monoethanolamine?
ʻO ka Monoethanolamine kahi mea hoʻohuihui me ka molecular formula c2h7no, wai kala ʻole.Hoʻohana ʻia ia e hoʻoneʻe i ke kinoea waikawa mai ke kinoea maoli a me ka ʻaila a me ka hana ʻana i ka mea holoi non-ionic, emulsifier, etc.
Ka inoa: monoethanolamine
Pōkole:MEA
Alias:2-aminoethanol;2-Aminoethyl alcoho
CAS: 141-43-5
ʻO ke kumu molekala: c2h7no
Kaumaha molekula: 61.0837
Ka helu hehee: 10.5 ℃
Puni paila: 170 ℃
Kekahi hau: – 5 ℃
Hōʻike hoʻohālikelike: 1.4540
Māmā pili: 1.0180 (20 / 4 ℃)
Kaila uila: 93.3 ℃
ʻO ka Monoethanolamine kahi wai viscous kala ʻole me ka ʻala o ka ammonia ma ke ana wela, hiki ke hoʻoheheʻe ʻia i ka wai, ikaika alkaline, hiki ke hoʻopili ʻia me ka wai, ethanol a me ka acetone, hiki ke hoʻoheheʻe iki ʻia i ka ether a me ka carbon tetrachloride.Ma 25 ℃, ʻo ka solubility ma benzene he 1.4%, ma ka ether he 2.1%, a ma ka carbon tetrachloride he 0.2%.Hiki iā ia ke komo i ka carbon dioxide a me ka hydrogen sulfide a hoʻokuʻu i ke kinoea i hoʻopaʻa ʻia ma hope o ka hoʻomehana ʻana.Hiki ke hoʻopau ʻia a hiki ke ʻā inā loaʻa ke ahi ākea a me ka wela nui.He mea make ka mahu.He hygroscopic kekahi.Loaʻa iā ia nā hopena emulsifying a foaming.Hiki iā ia ke hana i nā paʻakai me nā ʻakika inorganic a me nā mea hoʻokalakupua a me nā esters me ka anhydride.Hiki ke pani ʻia ka hydrogen atom ma kāna hui amino e acyl halide, haloalkane, etc
2. Ke noi nui
ʻO ka Monoethanolamine kekahi o nā mea waiwai kumu.Hoʻohana ʻia ia i ka ʻoihana lāʻau e synthesize l-cysteamine hydrochloride, taurine, anti infective drugs e like me furazolidone, morpholine biguanide, ketoconazole, anti parasitic drug tetraimidazole a me ka lāʻau cardiovascular Pansheng, etc.;Synthesis o olaquindox i ka ʻoihana lāʻau lapaʻau holoholona;Hoʻohana ʻia no ka synthesis o polyvinylpyrrolidone (PVP), ethylene imine a me polyethylene imine;ʻO ka hoʻohuihui ʻana o ka ethylenediamine kemika maikaʻi;ʻO ka mea hoʻomālamalama fluorescent i ka ʻoihana textile;ʻO ka hoʻohui ʻana o nā mea pena kiʻekiʻe i ka hoʻoluʻu a me ka ʻoihana kemika;Neutralizer i loko o ka ʻoihana pāpaʻi a me ka ʻoihana ʻeleʻele aila;Hoʻohana ʻia ia i ka hana ʻana i nā surfactants, nā mea hoʻokaʻawale, nā mea hoʻomaʻemaʻe, nā preservatives a me nā pena.
3. Hoʻokuʻu aku
4. Nā hana kōkua mua
5. ʻIkepili Kaʻa
Hebei Guanlang Biotechnology Co., Ltd. no Guanlang Group, i hoʻokumu ʻia i ka makahiki 2007, aia ma Shijiazhuang kūlanakauhale ʻo ia ke kapikala o Hebei Province a me ka ʻāpana hub ma waena o Beijing Tianjin a me Hebei a loaʻa iā ia ka pono o ka lawe ʻana.ʻO kā mākou hui kahi ʻoihana ʻenehana kiʻekiʻe hou me ka Research & Development, ka hana ʻana a me ke kūʻai aku.
