Igiciro cyiza cy'umukora Monoethanolamine CAS: 141-43-5

ibisobanuro bigufi:

Monoethanolamine ni ubwoko bwa amino alcohol ifite viscous hygroscopic, ikaba irimo amatsinda ya amine na alcohol. Monoethanolamine ikwirakwira cyane mu mubiri kandi ni igice cya lecithin. Monoethanolamine ifite ubwoko bwinshi bw'ibikorwa mu nganda. Urugero, Monoethanolamine ishobora gukoreshwa mu gukora imiti ikomoka ku buhinzi irimo ammonia ndetse no mu gukora imiti n'isabune. Monoethanolamine ishobora kandi gukoreshwa nk'umusemburo, fluorimetric reagent ndetse n'umusemburo wo gukuramo CO2 na H2S. Mu rwego rw'imiti, ethanolamine ikoreshwa nk'umusemburo wo gukamura imitsi y'amaraso. Monoethanolamine ifite kandi ubushobozi bwo kurwanya histamine, bugabanya ibimenyetso bibi biterwa no gufatana kwa H1-receptor.

Ibisobanuro

Imiterere y'umubiri: Monoethanolamine na triethanolamine ni ibinyobwa bitose, bidafite ibara, bisobanutse neza, kandi bifite hygroscopic ku bushyuhe bw'icyumba; diethanolamine ni crystalline solid. Etanolamine zose zikura amazi na dioxyde de carbone mu kirere kandi zishobora kuvangwa n'amazi na alcohol. Ubukonje bwa ethanolamine zose bushobora kugabanuka cyane iyo wongeyeho amazi.
Ethanolamines zikoreshwa cyane nk'ibikoresho by'ibanze mu gukora ibintu bifasha mu gukora surfactants, byaje kuba ingenzi mu bucuruzi nk'isabune, imiti ikoreshwa mu myenda n'uruhu, hamwe n'ibinyabutabire bigabanya ubushyuhe. Imikoreshereze yazo iva mu gucukura no gukata amavuta kugeza ku masabune yo kuvura n'ibikoresho byo kwiyuhagira byiza.

Imikoreshereze ya Monoethanolamine

1. Ethanolamine ikoreshwa nk'ikintu gifasha mu gukuraho dioxyde de carbone na hydrogen sulfide muri gaze karemano n'indi myuka, nk'ikintu cyoroshya uruhu, no mu gukwirakwiza imiti ikomoka ku buhinzi. Ethanolamine ikoreshwa kandi mu gusiga irangi, mu gusukura umusatsi, mu gutera imiti igabanya ubushyuhe, no mu gukora ibintu bikora ku buso (Beyer et al 1983; Mullins 1978; Windholz 1983). Ethanolamine yemerewe gukoreshwa mu bintu bigenewe gukoreshwa mu gukora, gutunganya, cyangwa gupakira ibiribwa (CFR 1981).
Ethanolamine igira ingaruka ku bintu nk'ibiranga amine z'ibanze n'ibikomoka kuri alkoholi. Ibintu bibiri by'ingenzi bya ethanolamine mu nganda bikubiyemo ingaruka ku mwuka wa dioxyde de carbone cyangwa hydrogen sulfide kugira ngo bitange imyunyungugu ishongesha mu mazi, n'ingaruka ku mwuka wa aside irike ndende kugira ngo habeho amasabune ya ethanolamine adafite aho ahuriye n'amazi (Mullins 1978). Ibinyabutabire bya ethanolamine byasimbuwe, nk'amasabune, bikoreshwa cyane nk'ibinyabutabire, ibinini, ibikoresho byo kogosha, n'isabune mu buryo bwo kwisiga (harimo n'ibisukura uruhu, amavuta yo kwisiga, n'amavuta yo kwisiga) (Beyer et al 1983).
2. Monoethanolamine ikoreshwa nk'ikintu gikwirakwiza imiti ikoreshwa mu buhinzi, mu gukora ibintu bikora ku buso, nk'ikintu cyoroshya uruhu, no mu bintu bigabanya ubushyuhe, isuku, n'ibisubizo by'umusatsi.
3. Nk'umuti ugabanya ubushyuhe; urinda kwangirika; mu gukora amavuta yo kwisiga, isabune, amarangi, n'amavuta yo gusiga.
4. Ikoreshwa nk'ikibuno; gukuraho dioxyde de carbone na hydrogen sulfide mu mvange ya gaze.
