Mtengo Wabwino Wopanga Monoethanolamine CAS:141-43-5

kufotokozera mwachidule:

Monoethanolamine ndi mtundu wa mowa wa amino womwe uli ndi viscous hygroscopic womwe uli ndi magulu a amine ndi mowa. Monoethanolamine imafalikira kwambiri m'thupi ndipo ndi gawo la lecithin. Monoethanolamine ili ndi mitundu yambiri ya ntchito zamafakitale. Mwachitsanzo, Monoethanolamine ingagwiritsidwe ntchito popanga mankhwala a zaulimi kuphatikizapo ammonia komanso kupanga mankhwala ndi sopo. Monoethanolamine ingagwiritsidwenso ntchito ngati surfactant, fluorimetric reagent komanso ngati chochotsera CO2 ndi H2S. M'munda wamankhwala, ethanolamine imagwiritsidwa ntchito ngati chothandizira mitsempha yamagazi. Monoethanolamine ilinso ndi mphamvu yoletsa histaminic, yomwe imachepetsa zizindikiro zoyipa zomwe zimayambitsidwa ndi kumangirira kwa H1-receptor.

Kapangidwe ka thupi: Monoethanolamine ndi triethanolamine ndi zamadzimadzi zokhuthala, zopanda mtundu, zoyera, komanso zosakanikirana bwino kutentha kwa chipinda; diethanolamine ndi chinthu cholimba cha kristalo. Ma ethanolamine onse amayamwa madzi ndi carbon dioxide kuchokera mumlengalenga ndipo amasakanikirana mosalekeza ndi madzi ndi mowa. Malo oundana a ethanolamines onse amatha kuchepetsedwa kwambiri powonjezera madzi.
Ma ethanolamine amagwiritsidwa ntchito kwambiri ngati othandizira popanga ma surfactants, omwe akhala ofunikira kwambiri pamalonda monga sopo, mankhwala a nsalu ndi zikopa, ndi ma emulsifiers. Ntchito zawo zimayambira pakubowola ndi kudula mafuta mpaka sopo wamankhwala ndi zimbudzi zapamwamba kwambiri.

Kugwiritsa Ntchito Monoethanolamine

1. Ethanolamine imagwiritsidwa ntchito ngati choyamwitsa kuti ichotse carbon dioxide ndi hydrogen sulfide kuchokera ku mpweya wachilengedwe ndi mpweya wina, ngati choyamwitsa khungu, komanso ngati choyamwitsa mankhwala a zaulimi. Ethanolamine imagwiritsidwanso ntchito mu zopukutira, njira zozungulira tsitsi, zosakaniza, komanso popanga zinthu zomwe zimagwira ntchito pamwamba (Beyer et al 1983; Mullins 1978; Windholz 1983). Ethanolamine imaloledwa m'zinthu zomwe zimagwiritsidwa ntchito popanga, kukonza, kapena kulongedza chakudya (CFR 1981).
Ethanolamine imakumana ndi zotsatira zomwe zimachitika ngati ma amine oyambira komanso ma alcohols. Zotsatira ziwiri zofunika kwambiri za ethanolamine m'mafakitale zimaphatikizapo kuchitapo kanthu ndi carbon dioxide kapena hydrogen sulfide kuti ipange mchere wosungunuka m'madzi, komanso kuchitapo kanthu ndi ma acid amafuta atali kuti apange sopo wa ethanolamine wosalowerera (Mullins 1978). Ma ethanolamine omwe amalowetsedwa m'malo mwake, monga sopo, amagwiritsidwa ntchito kwambiri ngati ma emulsifiers, thickeners, wetting agents, ndi sopo mu zodzoladzola (kuphatikizapo zotsukira khungu, mafuta odzola, ndi mafuta odzola) (Beyer et al 1983).
2. Monoethanolamine imagwiritsidwa ntchito ngati chotulutsira mankhwala a zaulimi, popanga zinthu zogwira ntchito pamwamba, monga chofewetsa khungu, komanso mu emulsifiers, polishes, ndi njira zothetsera tsitsi.
3. Monga mankhwala oletsa dzimbiri; popanga zodzoladzola, sopo, utoto, ndi ma polish.
4. Amagwiritsidwa ntchito ngati chotetezera; kuchotsa mpweya woipa wa carbon dioxide ndi hydrogen sulfide kuchokera ku zosakaniza za mpweya.
