Diethanolamine (DEA) CAS No. 111-42-2
Product Description
Diethanolamine, feem ntau abbreviated li DEA los yog DEOA, yog ib qho organic compound nrog cov mis HN (CH2CH2OH) 2. Ntshiab diethanolamine yog cov khoom dawb ntawm chav tsev kub, tab sis nws nyiam nqus dej thiab ua kom sov lub ntsiab lus uas nws feem ntau ntsib raws li tsis muaj xim, kua nplaum. Diethanolamine yog polyfunctional, ua ib tug thib ob amine thiab diol. Zoo li lwm cov organic amines, diethanolamine ua raws li lub hauv paus tsis muaj zog. Kev xav txog tus cwj pwm hydrophilic ntawm cov pab pawg amine thiab hydroxyl, DEA yog soluble hauv dej. Amides npaj los ntawm DEA feem ntau kuj hydrophilic. Hauv xyoo 2013, cov tshuaj tau muab cais los ntawm Lub Chaw Haujlwm Saib Xyuas Kev Tshawb Fawb Thoob Ntiaj Teb ntawm Cancer li "tejzaum nws tuaj yeem ua rau tib neeg".

Diethanolamine yog siv nyob rau hauv metalworking kua rau txiav, stamping thiab tuag-casting hauj lwm raws li ib tug corrosion inhibitor. Hauv kev tsim cov tshuaj detergents, tshuaj ntxuav, cov kuab tshuaj thiab cov dej ua haujlwm hlau, diethanolamine yog siv rau acid neutralization thiab av deposition. DEA yog qhov ua rau tawv nqaij khaus ntawm cov neeg ua haujlwm rhiab heev los ntawm kev cuam tshuam cov dej ua haujlwm hlau. Ib txoj kev tshawb fawb tau pom tias DEA inhibits cov nas me me rau kev nqus ntawm choline, uas yog qhov tsim nyog rau kev loj hlob ntawm lub hlwb thiab kev saib xyuas; [8] Txawm li cas los xij, kev tshawb fawb hauv tib neeg tau txiav txim siab tias kev kho mob dermal rau 1 lub hlis nrog cov tshuaj pleev ib ce muag muag uas muaj DEA ua rau DEA. Cov qib uas tau "deb qis dua cov concentrations cuam tshuam nrog perturbed hlwb kev loj hlob nyob rau hauv tus nas".Nyob rau hauv ib tug nas txoj kev tshawb no ntawm ntev raug rau inhaled DEA ntawm siab concentrations (txog 150 mg / m3), DEA tau pom los ntxias lub cev thiab lub cev hnyav hloov, Kev kho mob thiab kev hloov pauv histopathological, qhia txog cov ntshav me me, siab, lub raum thiab cov qog nqaij hlav hauv lub cev toxicity.
DEA yog qhov ua rau cov tawv nqaij khaus khaus hauv cov neeg ua haujlwm rhiab heev los ntawm kev raug dej-raws li cov khoom siv hlau ua haujlwm.Ib txoj kev tshawb fawb pom tias DEA inhibits hauv cov nas me me kom nqus tau cov choline, uas tsim nyog rau kev loj hlob ntawm lub hlwb thiab kev saib xyuas;[8] Txawm li cas los xij, kev tshawb fawb hauv tib neeg txiav txim siab tias kev kho mob dermal rau 1 lub hlis nrog cov tshuaj pleev ib ce muag muag uas muaj DEA ua rau cov qib DEA uas tau "deb qis dua cov concentrations cuam tshuam nrog perturbed hlwb kev loj hlob hauv nas". Hauv kev tshawb nrhiav nas ntawm kev kis tus kab mob ntev mus rau qhov nqus tau DEA ntawm qhov siab siab (siab dua 150 mg / m3), DEA tau pom tias ua rau lub cev thiab lub cev hnyav hloov pauv, kev kho mob thiab cov kab mob histopathological, qhia txog cov ntshav me, siab, lub raum thiab cov qog ntshav hauv lub cev. Ib txoj kev tshawb fawb 2009 pom tias DEA muaj peev xwm mob, mob ntev thiab subchronic toxicity zog rau cov tsiaj hauv dej.
Qhov zoo
Cov khoom lag luam zoo, kom muaj nuj nqis txaus, kev xa khoom zoo, kev pabcuam zoo Nws muaj qhov zoo dua li cov amine zoo sib xws, ethanolamine, nyob rau hauv qhov siab dua yuav siv tau rau tib lub peev xwm corrosion. Qhov no tso cai rau cov refiners los txhuam hydrogen sulfide ntawm qis dua amine tus nqi nrog tsawg zog siv tag nrho.
