Triethanolamine Triethanolamine kuj tseem hu ua peb yam amines ntxiv thiab triethanol. Nws yog cov kua roj tsis muaj xim nrog ntxhiab ammonia. Nws nqus dej tau yooj yim thiab hloov xim av thaum raug cua lossis raug lub teeb. Nws dhau los ua cov siv lead ua cubic tsis muaj xim lossis daj daj ntawm qhov kub qis.

Cov khoom siv tshuaj lom neeg:

Nws yog ib qho kua tsis muaj xim, pob tshab thiab khov ntawm chav tsev kub. Nws yog hygroscopic, muaj ntxhiab ammonia, yog alkaline, thiab yog khaus. Lub ntsiab lus yaj yog 21.2 ℃, lub ntsiab lus kub yog 360 ℃, lub ntsiab lus flash yog 193 ℃, Chemicalbook qhov ceev (d420) yog 1.1242, thiab qhov ntsuas refractive (nD20) yog 1.4852. Miscible hauv dej, ethanol thiab acetone, me ntsis soluble hauv ether, benzene thiab carbon tetrachloride.

Lub Hom Phiaj:

Siv ua kua huv rau kev tshem tawm cov pa roj carbon dioxide lossis hydrogen sulfide ntawm cov roj. Cov esters tsim ntawm triethanolamine thiab cov roj fatty acids siab dua yog siv dav ua cov tshuaj ntxuav, emulsifiers, humectants thiab lubricants, thiab kuj siv rau hauv kev npaj cov tshuaj pleev kom zoo nkauj. Triethanolamine kuj tseem siv ua cov tshuaj preservative, cov neeg sawv cev tiv thaiv dej, analytical reagent, thiab cov kuab tshuaj. Nws tuaj yeem siv ua tus activator hauv polymerization ntawm nitrile roj hmab, thiab kuj tuaj yeem siv ua emulsifier thiab stabilizer rau roj thiab waxes, thiab ua softener rau textiles nyob rau hauv acidic mob. Nws yog ib qho ntawm cov khoom ntawm spinning roj rau polyester thiab lwm yam synthetic fibers.

txoj kev tsim khoom

Nws yog pub ethylene oxide thiab ammonia dej rau hauv lub reactor, thiab ua qhov condensation reaction ntawm qhov kub ntawm 30-40 ° C thiab qhov siab ntawm 70.9-304kPa los tsim cov tshuaj sib xyaw ntawm mono-, di-, thiab triethanolamine, uas tau cua sov ntawm 90-120 ° C. Tom qab dehydration thiab concentration, nws raug xa mus rau peb lub tshuab nqus tsev Chemicalbook distillation towers rau kev nqus tsev distillation. Cov feem raug cuam tshuam raws li cov ntsiab lus boiling sib txawv kom tau txais monoethanolamine, diethanolamine thiab triethanolamine tiav cov khoom nrog qhov huv ntawm 99%. Thaum lub sijhawm ua haujlwm, yog tias qhov sib piv ntawm ethylene oxide nce ntxiv, qhov sib piv ntawm di- thiab triethanolamine yuav nce ntxiv, uas tuaj yeem ua rau kom muaj txiaj ntsig ntawm di- thiab triethanolamine.
