I-Diethanolamine (DEA) iyinhlanganisela ye-organic ene-chemical formula C4H11NO2. Iwuketshezi lwe-viscous olungenambala noma ikristalu ene-alkaline futhi ikwazi ukumunca amagesi afana ne-carbon dioxide ne-hydrogen sulfide emoyeni. I-Diethanolamine ehlanzekile iqinile emhlophe ekushiseni kwekamelo, kodwa ukuthambekela kwayo ekwenzeni ukudla okungenamsoco kanye ne-supercool kwenza ngezinye izikhathi ibonakale njengoketshezi olungenambala futhi olusobala. I-Diethanolamine, njenge-amine yesibili ne-diol, inokusetshenziswa okuningi ku-organic synthesis. Njengamanye ama-amine compounds, i-diethanolamine iyisisekelo esibuthakathaka. Ngo-2017, i-World Health Organization's International Agency for Research on Cancer yakhipha uhlu lwereferensi lokuqala lwe-carcinogens, futhi yafaka i-diethanolamine ohlwini lwe-Category 2B carcinogens. Ngo-2013, i-compound yaphinde yahlukaniswa ngokuthi "okungenzeka ukuthi i-carcinogenic kubantu" yi-International Agency for Research on Cancer.

Imisebenzi kanye nokusetshenziswa kwe-diethanolamine:

1. Isetshenziswa kakhulu njenge-asidi emunca igesi, i-non-ionic surfactant, i-emulsifier, i-ejenti yokupholisha, isihlanzi segesi yezimboni nesithambisi esifana ne-CO2, i-H2S ne-SO2. I-Iminodiethanol, eyaziwa nangokuthi i-diethanolamine, iyingxenye ye-glyphosate yokubulala ukhula. Isetshenziswa njengesihlanzi segesi nanjengento engavuthiwe yezidakamizwa zokwenziwa kanye ne-organic synthesis.

2. I-Diethanolamine iwumsebenzi ophakathi nendawo ku-organic synthesis. Isibonelo, ingasetshenziswa ukukhiqiza amanye ama-ejenti okuhlanza amehlo embonini yendwangu. Usawoti we-fatty acid we-morpholine ungasetshenziswa njengezilondolozi. I-Morpholine ingasetshenziswa futhi ukukhiqiza i-pholcodine yesimiso sezinzwa esicindezelayo. noma njenge-solvent. I-Diethanolamine isetshenziswa kukhemikhali yokuhlaziya njengesixazululo esimile se-reagent kanye negesi ye-chromatography yokugcina ngokukhetha futhi ihlukanise utshwala, ama-glycols, ama-amine, ama-pyridine, ama-quinolines, ama-piperazines, ama-thiols, ama-thioethers, namanzi.

3. I-Diethanolamine iyi-corrosion inhibitor ebalulekile futhi ingasetshenziswa njenge-corrosion inhibitor ekwelapheni kwamanzi okubhayela, i-coolant yenjini yemoto, uwoyela wokumba nokusika, nezinye izinhlobo zamafutha okugcoba. Iphinde isetshenziswe kugesi yemvelo njengesimunca sokuhlanza amagesi e-asidi. Isetshenziswa njenge-emulsifier kuzimonyo ezahlukene kanye nemithi. Embonini yendwangu, ingasetshenziswa njenge-lubricant, i-ejenti yokumanzisa, isithambisa nezinye izinto zokwenziwa ze-organic zokwenziwa.

4. Isetshenziswa njenge-asidi emuncayo, i-plasticizer, i-softener, i-emulsifier, njll. kuma-adhesives. Ibuye isetshenziselwe ukumunca amagesi ane-acidic (njenge-hydrogen sulfide, i-carbon dioxide, njll.) ku-petroleum gas, igesi yemvelo namanye amagesi. Kuyinto impahla eluhlaza for synthesis imithi, izibulala-zinambuzane, udayi intermediates kanye surfactants. Isetshenziswa njenge-emulsifier yamafutha namawaksi, kanye nesithambisa sesikhumba nemicu yokwenziwa ngaphansi kwezimo ezine-asidi. Isetshenziswa njenge-thickener kanye nesithuthukisi segwebu kuma-shampoos nama-detergents alula. Ibuye isetshenziselwe okokuhlanza, okokugcoba, okokukhanyisa kanye nesikhiphi sothuli se-piston.

5. Isetshenziswa njenge-ejenti eyinkimbinkimbi ye-silver plating, i-cadmium plating, i-lead plating, i-zinc plating, njll.

6. Isetshenziswa njengama-reagents okuhlaziya, izinto ezimunca igesi ye-asidi, izithambisa kanye nezinto zokugcoba, naku-organic synthesis.
