I-Monoethanolamine (2-aminoethanol ethanolamine)

Uhlobo lwekhemikhali

I-Ethanolamine luhlobo lwe-viscous hygroscopic amino alcohol equlethe amaqela eekhemikhali ze-amine kunye ne-alcohol. Isasazwa kakhulu emzimbeni kwaye yinxalenye ye-lecithin. Ineentlobo ezininzi zezicelo zoshishino. Umzekelo, ingasetyenziswa ekuveliseni iikhemikhali zezolimo kuquka i-ammonia kunye nokuveliswa kwamayeza kunye neesepha. Ingasetyenziswa njenge-surfactant, i-reagent ye-fluorimetric kunye ne-arhente yokususa i-CO2 kunye ne-H2S. Kwicandelo lamayeza, i-ethanolamine isetyenziswa njenge-arhente ye-Vascular Sclerosing. Ikwanayo nepropati ye-antihistaminic, enciphisa iimpawu ezimbi ezibangelwa kukubopha kwe-H1-receptor.

Izicelo

I-Ethanolamine isetyenziswa njenge-arhente yokufunxa ukususa i-carbon dioxide kunye ne-hydrogen sulfide kwigesi yendalo nakwezinye iigesi, njenge-arhente yokuthambisa izikhumba, kunye ne-arhente yokusasaza iikhemikhali zezolimo. I-Ethanolamine ikwasetyenziswa kwii-polish, izisombululo zokushukuma kweenwele, ii-emulsifiers, kunye nokuhlanganiswa kwee-arhente ezisebenzayo kumphezulu (Beyer et al 1983; Mullins 1978; Windholz 1983). I-Ethanolamine ivumelekile kwizinto ezenzelwe ukusetyenziswa kwimveliso, ekucutshungulweni, okanye ekupakishweni kokutya (CFR 1981).

I-Ethanolamine ifumana iimpendulo eziphawulekayo kwi-amines eziphambili kunye nee-alcohols. Iimpendulo ezimbini ezibalulekileyo kwishishini ze-ethanolamine ziquka ukuphendula nge-carbon dioxide okanye i-hydrogen sulfide ukuze kuvele iityuwa ezinyibilikayo emanzini, kunye nokuphendula nge-long chain fatty acids ukwenza isepha ze-ethanolamine ezingathathi hlangothi (Mullins 1978). Iikhompawundi ze-ethanolamine ezithathelwe indawo, ezifana neesepha, zisetyenziswa kakhulu njengeemulsifiers, thickeners, wetting agents, kunye ne-detergents kwi-cosmetic formulations (kubandakanya izicoci zesikhumba, iikhrimu, kunye ne-lotions) (Beyer et al 1983).
