Ethanolamine (CAS 141-43-5) yog dab tsi?
Ethanolamine, tseem hu ua 2-aminoethanol, yog ib qho kev sib xyaw ua ke uas tau siv dav hauv ntau lub lag luam vim nws cov khoom tshwj xeeb. Cov kua tsis muaj xim, tsis muaj kuab paug no yog ib qho tseem ceeb hauv lub tsev thaiv hauv kev sib txuas ntawm surfactants, emulsifiers, thiab corrosion inhibitors.
Dab tsi yog qhov kub ntawm ethanolamine?
Ethanolamine, tseem hu ua 2-aminoethanol lossis MEA, muaj cov mis mos molecular C₂H₇NO. Nws yog ib qho tsis hloov pauv organic amine compound nrog cov khoom siv yooj yim.
Ethanolamine muaj ibKub taw tes ntawm 170 degree, faib nws raws li qhov qis - boiling -point amine thiab nws kuj yog dej -soluble. Raws li ambient kub nce, lub zog nyob rau hauv lub ethanolamine molecule tsis tu ncua nce, txo cov kev cuam tshuam ntawm cov molecule kev sib cuam tshuam nrog nws ib puag ncig, nws thiaj li ua rau evaporation mus rau hauv lub gaseous xeev. Qhov qis qis ntawm ethanolamine muaj feem xyuam rau cov qauv hydrogen bonding ntawm nws cov molecules.

Ethanolamine (CAS 141-43-5) Kev siv
Ethanolamine (xws li monoethanolamine, diethanolamine, thiab triethanolamine) yog ib qho tseem ceeb organic compound nrog ntau yam kev lag luam. Nws lub luag haujlwm tseem ceeb suav nrog ua cov tshuaj reagent, hnyav, emulsifier, roj hmab accelerator, corrosion inhibitor, thiab degradation agent. Nws cov ntawv thov siv ntau yam kev lag luam, xws li tshuaj lom neeg, tshuaj, ua liaj ua teb, textile, thiab roj av.
- Chemical Reagent thiab Solvent: Ethanolamine feem ntau yog siv los ua cov tshuaj reagent hauv cov chaw kuaj tshuaj rau kev sib txuas ntawm lwm cov organic sib txuas. Vim nws zoo solubility, nws kuj yog siv los ua ib qho hnyav, tshwj xeeb tshaj yog nyob rau hauv cov xim thiab cov tshuaj ntxuav.
- Emulsifier: Ethanolamine yog siv los ua ib qho emulsifier hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej, pab cov roj thiab dej sib tov los tsim cov emulsion ruaj khov.
- Roj Hmab Accelerator: Hauv kev lag luam roj hmab, ethanolamine yog siv los ua tus accelerator kom ceev cov txheej txheem vulcanization ntawm roj hmab thiab txhim kho kev ua haujlwm ntawm cov khoom siv roj hmab.
