Diethanolamine 111-42-2 puriy: ≥99%

Keeb Kwm:

Ethanolamine (EA) yog cov amino cawv tseem ceeb tshaj plaws, suav nrog monoethanolamine (MEA), diethanolamine (DEA), thiab triethanolamine (TEA). Ethanolamine yog ib qho tseem ceeb organic intermediate siv dav hauv surfactants, synthetic detergents, petroleum additives, synthetic resin thiab roj hmab plasticizers, accelerators, vulcanizers, thiab foaming agents, nrog rau hauv kev ntxuav roj, kua antifreeze, luam ntawv thiab dyeing, tshuaj, tshuaj tua kab, kev tsim kho, thiab kev siv tub rog. Ntau yam ntawm ethanolamine cov khoom lag luam downstream yog cov tshuaj intermediates zoo tseem ceeb thiab kuj tsis muaj nyob hauv Suav teb. Yog li ntawd, kev siv zog ntxiv hauv kev tsim thiab siv ethanolamine yog qhov tseem ceeb rau ob qho tib si kom tau raws li qhov xav tau tshuaj zoo hauv tsev thiab txhawb kev loj hlob sai ntawm kev lag luam ethanolamine.

Diethanolamine, tseem hu ua bishydroxyethylamine thiab 2,2′-iminobisethanol, yog cov kua dawb crystalline lossis tsis muaj xim nrog lub zog hygroscopicity. Nws yooj yim yaj hauv dej, methanol, ethanol, acetone, thiab benzene. Nws solubility hauv benzene (g/100g) ntawm 25°C yog 4.2, thiab hauv ether nws yog 0.8. Nws siv suav nrog: lub tshuab lim roj, nqus cov pa roj acidic uas muaj tshuaj lom neeg xws li carbon dioxide, hydrogen sulfide, thiab sulfur dioxide. "Benfil" kua, siv hauv kev lag luam ammonia synthesis, feem ntau yog tsim los ntawm cov khoom no. Nws kuj tseem siv ua emulsifier, roj nplua nyeem, tshuaj zawv plaub hau, thickener, thiab lwm yam additives. Nws yog ib qho organic synthesis intermediate siv hauv kev tsim cov khoom siv ntxuav khaub ncaws, preservatives, thiab cov khoom siv tshuaj txhua hnub (xws li surfactants). Nws kuj tseem siv hauv kev tsim morpholine.

Siv: Diethanolamine siv ua cov khoom siv raw rau cov buffers hauv kev lag luam tshuaj, ua tus neeg sawv cev sib txuas hauv kev tsim cov ua npuas polyurethane uas muaj zog heev, thiab ua cov tshuaj ntxuav rau cov pistons ntawm lub cav dav hlau thaum sib xyaw nrog triethanolamine. Nws teb nrog cov roj fatty acids los ua alkyl cawv acyl. Nws kuj siv ua cov khoom siv raw rau kev tsim cov organic, cov khoom siv tshuaj lom neeg rau cov surfactants, thiab cov roj acid absorbent. Nws siv ua cov khoom siv thickener thiab foam modifier hauv cov tshuaj zawv plaub hau thiab cov tshuaj ntxuav lub teeb, ua cov khoom nruab nrab hauv kev lag luam organic synthesis, thiab ua cov kuab tshuaj hauv kev lag luam tshuaj. Nws muaj ntau yam kev siv hauv kev lag luam ntxuav khaub ncaws, kev lag luam tshuaj pleev ib ce, kev ua liaj ua teb, kev lag luam tsim kho, thiab kev lag luam hlau.
