Diethanolamine (DEA) CAS No. 111-42-2
Mafotokozedwe Akatundu
Diethanolamine, yomwe nthawi zambiri imafupikitsidwa ngati DEA kapena DEOA, ndi organic pawiri ndi chilinganizo HN(CH2CH2OH)2. Diethanolamine yoyera ndi yolimba yoyera kutentha kwa chipinda, koma zizoloŵezi zake zoyamwa madzi ndi supercool kutanthauza kuti nthawi zambiri zimakhala ngati madzi opanda mtundu, a viscous. Diethanolamine ndi polyfunctional, pokhala amine yachiwiri ndi diol. Monga ma organic amines, diethanolamine imakhala ngati maziko ofooka. Kuwonetsa mawonekedwe a hydrophilic a magulu achiwiri amine ndi hydroxyl, DEA imasungunuka m'madzi. Amides okonzedwa kuchokera ku DEA nthawi zambiri amakhalanso hydrophilic. Mu 2013, mankhwalawo adasankhidwa ndi International Agency for Research on Cancer kuti "mwina akhoza kuyambitsa khansa kwa anthu".

Kugwiritsa ntchito
| Zoyezera mpweya wa asidi, zopangira mafuta osagwiritsa ntchito ayoni, zopangira ma emulsifiers, zopukutira, zoyeretsera gasi m'mafakitale, zothira mafuta. |
Diethanolamine amagwiritsidwa ntchito m'madzi opangira zitsulo podula, kupondaponda ndi kuponyera kufa ngati choletsa corrosion inhibitor. Popanga zotsukira, zotsukira, zosungunulira nsalu ndi madzi opangira zitsulo, diethanolamine amagwiritsidwa ntchito pochotsa asidi komanso kuyika nthaka. DEA ndi chinthu chokhumudwitsa pakhungu mwa ogwira ntchito omwe amadziwitsidwa ndi madzi opangira zitsulo. Kafukufuku wina adawonetsa kuti DEA imalepheretsa kuyamwa kwa choline mu mbewa za ana, zomwe ndizofunikira kuti ubongo ukule ndi kukonzanso; Mu kafukufuku wa mbewa wokhudzana ndi kukhudzidwa kwapang'onopang'ono kwa DEA pazambiri (pamwamba pa 150 mg/m3), DEA idapezeka kuti imapangitsa kusintha kwa thupi ndi chiwalo, matenda ndi histopathological kusintha, kusonyeza wofatsa magazi, chiwindi, impso ndi testicular zokhudza zonse kawopsedwe.
DEA ndi chinthu chomwe chingakhumudwitse khungu mwa ogwira ntchito omwe amakhudzidwa ndi kukhudzana ndi madzi opangira zitsulo. Kafukufuku wina anasonyeza kuti DEA imalepheretsa mbewa za ana kuyamwa kwa choline, komwe kuli kofunikira kuti ubongo ukule ndi kukonzanso;[8] Komabe, kafukufuku wa anthu. adatsimikiza kuti chithandizo chamankhwala kwa mwezi wa 1 ndi mafuta odzola akhungu omwe amapezeka pamalonda omwe ali ndi DEA adapangitsa kuti milingo ya DEA ikhale "yotsika kwambiri yomwe imalumikizidwa ndi kusokonezeka kwaubongo mu mbewa". Mu kafukufuku wa mbewa wokhudzana ndi nthawi yayitali ya DEA yopumira pamtunda wambiri (pamwamba pa 150 mg / m3), DEA idapezeka kuti imapangitsa kusintha kwa thupi ndi ziwalo za thupi, kusintha kwachipatala ndi histopathological, kusonyeza magazi ochepa, chiwindi, impso ndi testicular systemic toxicity. Kafukufuku wa 2009 adapeza kuti DEA imatha kukhala ndi poizoni wowopsa, wosakhazikika komanso wosakhazikika pazamoyo zam'madzi.
Ubwino
Ubwino wazinthu, kuchuluka kokwanira, kuperekera kogwira mtima, ntchito yabwino kwambiri Imakhala ndi mwayi wopitilira amine wofanana, ethanolamine, chifukwa kuchuluka kwakukulu kungagwiritsidwe ntchito pakuwonongeka komweko. Izi zimathandiza oyenga kutsuka hydrogen sulfide pamlingo wocheperako wozungulira wa amine osagwiritsa ntchito mphamvu zonse.
