Chaw Tsim Khoom Zoo Tus Nqi Monoethanolamine CAS: 141-43-5

piav qhia luv luv:

Monoethanolamine yog ib hom amino alcohol uas muaj viscous hygroscopic thiab muaj ob pawg tshuaj amine thiab cawv. Monoethanolamine muaj ntau yam nyob hauv lub cev thiab yog ib feem ntawm lecithin. Monoethanolamine muaj ntau yam kev siv hauv kev lag luam. Piv txwv li, Monoethanolamine siv tau rau hauv kev tsim cov tshuaj ua liaj ua teb xws li ammonia thiab kev tsim cov tshuaj thiab cov tshuaj ntxuav tes. Monoethanolamine kuj siv tau ua surfactant, fluorimetric reagent thiab tshem tawm CO2 thiab H2S. Hauv kev lag luam tshuaj, ethanolamine siv ua vascular sclerosing agent. Monoethanolamine kuj muaj cov khoom antihistamine, uas txo cov tsos mob tsis zoo los ntawm H1-receptor binding.

Kev piav qhia

Cov khoom siv lub cev: Monoethanolamine thiab triethanolamine yog cov kua nplaum, tsis muaj xim, ntshiab, hygroscopic ntawm chav tsev kub; diethanolamine yog cov khoom siv crystalline. Tag nrho cov ethanolamines nqus dej thiab carbon dioxide los ntawm huab cua thiab sib xyaw nrog dej thiab cawv. Cov ntsiab lus khov ntawm txhua yam ethanolamines tuaj yeem txo qis ntau los ntawm kev ntxiv dej.
Cov tshuaj ethanolamines siv dav dav ua cov khoom nruab nrab hauv kev tsim cov surfactants, uas tau dhau los ua qhov tseem ceeb hauv kev lag luam xws li cov tshuaj ntxuav tes, cov tshuaj textile thiab tawv, thiab cov tshuaj emulsifiers. Lawv siv ntau yam los ntawm kev khawb thiab txiav roj mus rau cov xab npum kho mob thiab cov khoom siv hauv chav dej zoo.

Cov ntawv thov ntawm Monoethanolamine

1. Ethanolamine siv ua ib yam khoom siv nqus kom tshem tawm cov pa roj carbon dioxide thiab hydrogen sulfide ntawm cov roj av thiab lwm yam pa roj, ua ib yam khoom siv ua kom tawv mos, thiab ua ib yam khoom siv tawg rau cov tshuaj ua liaj ua teb. Ethanolamine kuj siv rau hauv cov tshuaj pleev xim, cov tshuaj pleev plaub hau, cov tshuaj emulsifiers, thiab hauv kev tsim cov tshuaj surfactant (Beyer et al 1983; Mullins 1978; Windholz 1983). Ethanolamine raug tso cai rau hauv cov khoom siv rau kev tsim khoom, kev ua, lossis kev ntim khoom noj (CFR 1981).
Ethanolamine dhau los ua cov tshuaj tiv thaiv ntawm cov amines thawj zaug thiab cov cawv. Ob qho tshuaj tiv thaiv tseem ceeb hauv kev lag luam ntawm ethanolamine suav nrog kev tiv thaiv nrog carbon dioxide lossis hydrogen sulfide kom ua rau cov ntsev uas yaj tau hauv dej, thiab kev tiv thaiv nrog cov roj fatty acids ntev los tsim cov xab npum ethanolamine tsis muaj zog (Mullins 1978). Cov tshuaj ethanolamine hloov pauv, xws li xab npum, siv dav dav ua cov emulsifiers, thickeners, wetting agents, thiab detergents hauv cov tshuaj pleev ib ce (suav nrog cov tshuaj ntxuav tawv nqaij, creams, thiab lotions) (Beyer et al 1983).
2. Monoethanolamine siv ua tus neeg sawv cev rau cov tshuaj ua liaj ua teb, hauv kev tsim cov neeg sawv cev ntawm cov khoom siv saum npoo av, ua tus neeg sawv cev mos rau cov tawv nqaij, thiab hauv cov tshuaj emulsifiers, polishes, thiab cov tshuaj pleev plaub hau.
3.Ua ib qho tshuaj nruab nrab; tshuaj tiv thaiv xeb; hauv kev tsim cov tshuaj pleev ib ce, tshuaj ntxuav, xim, thiab txhuam.
4. Siv ua buffer; tshem tawm cov pa roj carbon dioxide thiab hydrogen sulfide ntawm cov roj sib xyaw.
