Diethanolamine (DEA) ke motsoako oa manyolo o nang le foromo ea lik'hemik'hale C4H11NO2. Ke mokelikeli o se nang 'mala oa viscous kapa kristale e nang le alkaline 'me e ka monya likhase tse kang carbon dioxide le hydrogen sulfide moeeng. Diethanolamine e hloekileng ke 'mala o mosoeu o tiileng mocheso oa kamore, empa tšekamelo ea eona ea ho ja lijo tse monate le supercool e etsa hore ka linako tse ling e bonahale e le mokelikeli o se nang mebala le o bonaletsang. Diethanolamine, joalo ka amine ea bobeli le diol, e na le litšebeliso tse ngata ho organic synthesis. Joalo ka metsoako e meng ea amine, diethanolamine ke motheo o fokolang. Ka 2017, Setsi sa Machaba sa Lipatlisiso sa Mokhatlo oa Lefatše oa Bophelo bakeng sa Lipatlisiso ka Kankere se ile sa lokolla lethathamo la litšupiso tsa li-carcinogens, 'me la kenyelletsa diethanolamine lethathamong la Category 2B carcinogens. Ka 2013, motsoako o ile oa boela oa hlalosoa e le "mohlomong oa kankere ho batho" ke Mokhatlo oa Machaba oa Lipatlisiso ka Kankere.

Mesebetsi le tšebeliso ea diethanolamine:

1. Haholo-holo e sebelisoa e le acid e monyang khase, non-ionic surfactant, emulsifier, bencheng agent, indasteri e hloekisang khase le lubricant tse kang CO2, H2S le SO2. Iminodiethanol, eo hape e tsejoang e le diethanolamine, ke karolo e bohareng ea glyphosate ea herbicide. E sebelisoa e le sehloekisi sa khase hape e le thepa e tala bakeng sa lithethefatsi tsa maiketsetso le motsoako oa manyolo.

2. Diethanolamine ke karolo e bohareng ea motsoako oa manyolo. Mohlala, e ka sebelisoa ho hlahisa li-optical bleaching agents indastering ea masela. Matsoai a mafura a morpholine a ka sebelisoa e le li-preservative. Morpholine e ka boela ea sebelisoa ho hlahisa pholcodine ea tsamaiso ea methapo ea methapo. kapa joalo ka sehlapi. Diethanolamine e sebelisoa k'hemistri ea ho hlahloba e le tharollo ea reagent le ea khase ea chromatography ho boloka le ho arola joala, glycols, amines, pyridines, quinolines, piperazines, thiols, thioethers le metsi.

3. Diethanolamine ke corrosion inhibitor ea bohlokoa 'me e ka sebelisoa e le corrosion inhibitor ho phekolo ea metsi a boiler, mochine o pholileng oa koloi, ho cheka le ho seha oli, le mefuta e meng ea oli e tlotsang. E boetse e sebelisoa khase ea tlhaho e le monyetla bakeng sa ho hloekisa likhase tsa asiti. E sebelisoa e le emulsifier ho litlolo le meriana e fapaneng. Indastering ea masela, e ka sebelisoa e le setlolo, sesebelisoa sa ho kolobisa, se nolofatsang le lisebelisoa tse ling tsa tlhaho tsa maiketsetso.

4. E sebelisoa e le acid e monyang, plasticizer, softener, emulsifier, joalo-joalo ka likhomaretsi. E boetse e sebelisoa e le monya bakeng sa likhase tse nang le asiti (joalo ka hydrogen sulfide, carbon dioxide, joalo-joalo) ka khase ea petroleum, khase ea tlhaho le likhase tse ling. Ke thepa e tala bakeng sa ho kopanya meriana, chefo e bolaeang likokoanyana, li-intermediates tsa dae le li-surfactants. E sebelisoa e le emulsifier bakeng sa oli le boka, le se bonolo bakeng sa letlalo le likhoele tsa maiketsetso tlas'a maemo a asiti. E sebelisoa e le sesebelisoa se matlafatsang le ho ntlafatsa foam ho li-shampoo le li-detergents tse bobebe. E boetse e sebelisoa e le sesepa, lubricant, lightener le enjene ea ho tlosa lerole la piston.

5. E sebelisoa e le ntho e rarahaneng bakeng sa ho roala silevera, cadmium plating, lead plating, zinc plating, joalo-joalo.
