Feem ntau Diethanolamine tshwm sim ua kua tsis muaj xim pob tshab lossis siv lead ua thaum sov li chav tsev, thiab muaj ntxhiab tsw ammonia me ntsis.

Tshwj xeeb, qhov melting point ntawm diethanolamine yog 28 ℃ thiab qhov boiling point yog 268.8 ℃. Nws yuav zoo li cov kua tsis muaj xim pob tshab ntawm chav tsev kub vim yog deliquescence thiab supercooling.

Tsis tas li ntawd xwb, nws sib xyaw nrog dej, methanol, acetone, thiab lwm yam, thiab yaj me ntsis hauv cov kuab tshuaj xws li benzene, ether, carbon tetrachloride, thiab n-heptane.

Diethanolamine yog ib qho organic compound uas muaj ntau yam kev siv. Nws yog siv dav hauv ntau qhov chaw xws li tshuaj, tshuaj pleev ib ce, kev lag luam tshuaj lom neeg, thiab kev kho roj.

Hauv kev kho mob, diethanolamine siv tau los ua tshuaj pleev rau qee yam kab mob ntawm daim tawv nqaij xws li eczema thiab psoriasis. Nws txoj kev ua haujlwm yog txo cov tsos mob xws li o ntawm daim tawv nqaij thiab khaus los ntawm kev txwv tsis pub muaj kev o thiab kev loj hlob ntawm cov hlwb tawv nqaij.

Hauv kev lag luam tshuaj pleev ib ce, diethanolamine feem ntau siv rau hauv cov tshuaj pleev ib ce xws li cov khoom saib xyuas tawv nqaij thiab cov tshuaj pleev thaiv hnub vim nws cov tshuaj antioxidant, moisturizing thiab anti-ultraviolet. Ua ib qho emulsifier thiab pH regulator, nws pab cov khoom sib tov zoo dua thiab nyob ruaj khov, thaum kho qhov pH ntawm cov khoom kom nws haum rau daim tawv nqaij.

Hauv kev lag luam tshuaj lom neeg, diethanolamine siv dav dua. Nws tuaj yeem siv ua cov roj acid absorbent kom nqus tau cov pa phem xws li carbon dioxide thiab hydrogen sulfide hauv huab cua thiab ntxuav ib puag ncig. Tib lub sijhawm, nws tseem yog cov khoom siv tseem ceeb rau kev tsim cov organic compounds, xws li surfactants thiab polymers, thiab siv dav hauv kev tsim cov tshuaj ntxuav tes, polishes, lubricants, softeners, surfactants thiab lwm yam khoom. Tsis tas li ntawd, diethanolamine kuj tseem siv tau ua tus neeg sawv cev qeeb qeeb rau kev kho dej boiler thiab ua ib qho nruab nrab rau cov tshuaj tua kab glyphosate.

Tsis tas li ntawd xwb, diethanolamine kuj tseem ua lub luag haujlwm tseem ceeb hauv kev ntxuav roj, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem ntawm cov roj ntuj thiab roj av refining, rau kev tshem tawm cov pa roj acidic xws li carbon dioxide thiab hydrogen sulfide los txhim kho cov roj zoo. Hauv kev lag luam tshuaj tua kab thiab tshuaj, diethanolamine, ua ib qho tseem ceeb nruab nrab, tuaj yeem txhim kho kev ruaj khov thiab kev ua haujlwm ntawm cov tshuaj tua kab thiab tshuaj.

Feem ntau, diethanolamine muaj txiaj ntsig zoo rau ntau qhov chaw vim nws cov khoom tshwj xeeb thiab ntau yam kev siv.
