Monoethanolamine (MEA) CAS Numera 141-43-5

E mafai ona gaosia le MEA e ala i le fa'afefeina o le ammonia/vai ma le ethylene oxide i le mamafa o le 50-70 pa e fa'atumauina ai le ammonia i le vaega vai. O le faagasologa e exothermic ma e le manaʻomia se faʻamalosi. Ole fua ole ammonia ma le ethylene oxide e taua tele i le filifilia o le tuufaatasiga o le paluga e maua. Afai e tali le ammonia ma le mole e tasi o le ethylene oxide, ua faia le monoethanolamine, faatasi ai ma mole mole e lua o le ethylene oxide, e fai le diethanolamine ae tolu mole o le ethylene oxide triethanolamine ua fausia. A maeʻa le tali, o le faʻamaʻiina o le paluga e maua mai e faia muamua e aveese ai le sili atu o le amonia ma le vai. Ona tuueseeseina lea o amine e faaaoga ai se seti o le distillation e tolu-laasaga.

Monoethanolamine o loʻo faʻaaogaina e pei o vailaʻau faʻamaʻi, vailaʻau faʻamaʻi, vailaʻau, solvents, intermediates vali, paʻu accelerators, inhibitors corrosion ma surfactants, ma isi E faʻaaogaina foi e pei o le kasa acid absorbents, emulsifiers, plasticizers, paʻu vulcanizing agents, lomitusi ma vali Whitening sui, ie. anti-moth agent, ma isi. E mafai foi ona faʻaaogaina e avea o se plasticizer, vulcanizing agent, accelerator ma le foaming agent mo resins synthetic ma paʻu, faʻapea foʻi ma intermediates mo vailaau faʻasaina, vailaʻau ma vali. O se mea mataʻina foʻi mo vailaʻau faʻapipiʻi, emulsifiers mo cosmetics, ma isi pisinisi textile e pei o le lomitusi ma le valiina o le susulu, antistatic agent, anti-moth agent, detergent. E mafai fo'i ona fa'aogaina e pei o se kaponi carbon dioxide absorber, vaitusi fa'aopoopo, ma suau'u fa'aopoopo.
