Kev ua haujlwm thiab kev siv ntawm diethanolamine

Diethanolamine (DEA) yog cov organic compound nrog cov tshuaj formula C4H11NO2. Nws yog cov kua dej tsis muaj xim lossis siv lead ua uas muaj alkaline thiab tuaj yeem nqus cov pa roj xws li carbon dioxide thiab hydrogen sulfide hauv huab cua. Ntshiab diethanolamine yog cov khoom dawb ntawm chav tsev kub, tab sis nws txoj kev nyiam rau deliquesce thiab supercool ua rau qee zaum nws tshwm sim ua kua tsis muaj xim thiab pob tshab. Diethanolamine, raws li ib tug thib ob amine thiab diol, muaj ntau siv nyob rau hauv cov organic synthesis. Zoo li lwm cov amine compounds, diethanolamine tsis muaj zog. Xyoo 2017, Lub Koom Haum Ntiaj Teb Kev Noj Qab Haus Huv Lub Koom Haum Thoob Ntiaj Teb rau Kev Tshawb Fawb Txog Kev Tshawb Fawb tau tshaj tawm cov npe ua ntej siv cov carcinogens, thiab suav nrog diethanolamine hauv cov npe ntawm Qib 2B carcinogens. Nyob rau hauv 2013, lub compound kuj raug cais raws li "tejzaum carcinogenic rau tib neeg" los ntawm International Agency for Research on Cancer.

Kev ua haujlwm thiab kev siv ntawm diethanolamine

1. Feem ntau yog siv los ua cov pa roj carbon dioxide, uas tsis yog-ionic surfactant, emulsifier, polishing tus neeg sawv cev, muaj roj purifier thiab roj nplua nyeem xws li CO2, H2S thiab SO2. Iminodiethanol, tseem hu ua diethanolamine, yog ib qho nruab nrab ntawm cov tshuaj tua kab mob glyphosate. Nws yog siv los ua cov roj purifier thiab ua cov khoom siv raw rau cov tshuaj hluavtaws thiab cov organic synthesis.

2. Diethanolamine yog ib qho nruab nrab ntawm cov organic synthesis. Piv txwv li, nws tuaj yeem siv los tsim qee cov tshuaj kho qhov muag hauv kev lag luam textile. Fatty acid ntsev ntawm morpholine tuaj yeem siv los ua cov tshuaj tua kab mob. Morpholine kuj tseem siv tau los tsim lub hauv paus paj hlwb kev nyuaj siab tshuaj pholcodine. los yog ua kuab tshuaj. Diethanolamine yog siv nyob rau hauv analytical chemistry raws li ib tug reagent thiab roj chromatography nyob twj ywm tov rau xaiv khaws cia thiab cais cawv, glycols, amines, pyridines, quinolines, piperazines, thiols, thioethers, thiab dej.

3. Diethanolamine yog ib qho tseem ceeb corrosion inhibitor thiab yuav siv tau raws li ib tug corrosion inhibitor nyob rau hauv boiler dej kho, tsheb cav coolant, drilling thiab txiav cov roj, thiab lwm yam roj lubricating. Kuj tseem siv rau hauv cov pa roj carbon monoxide ua ib qho nqus rau purifying acid gases. Siv ua emulsifier hauv ntau yam tshuaj pleev ib ce thiab tshuaj. Hauv kev lag luam textile, nws tuaj yeem siv los ua cov roj nplua nyeem, tus neeg sawv cev ntub dej, softener thiab lwm yam khoom siv hluavtaws organic.

4. Siv los ua kua qaub, plasticizer, softener, emulsifier, thiab lwm yam hauv cov nplaum. Nws kuj tseem siv los ua cov khoom nqus dej rau cov kua qaub (xws li hydrogen sulfide, carbon dioxide, thiab lwm yam) hauv cov roj av, cov pa roj ntsha thiab lwm yam roj. Nws yog cov khoom siv raw rau kev sib txuas ntawm cov tshuaj, tshuaj tua kab, tshuaj tua kab mob thiab surfactants. Siv ua emulsifier rau roj thiab waxes, thiab softener rau tawv thiab hluavtaws fibers nyob rau hauv acidic tej yam kev mob. Siv raws li ib tug thickener thiab ua npuas ncauj txhim kho nyob rau hauv cov tshuaj zawv plaub hau thiab lub teeb detergents. Nws kuj yog siv los ua tshuaj ntxuav tes, roj nplua nyeem, ci ci thiab lub cav piston plua plav tshem tawm.

5. Siv raws li tus neeg sawv cev complexing rau nyiaj plating, cadmium plating, txhuas plating, zinc plating, thiab lwm yam.

6. Siv raws li kev soj ntsuam reagents, acid gas absorbents, softeners thiab lubricants, thiab nyob rau hauv cov organic synthesis.
