Iimveliso
Diethanolamine (DEA) CAS No. 111-42-2
Ingcaciso yeMveliso
I-Diethanolamine, ehlala ifinyeziwe njenge-DEA okanye i-DEOA, i-organic compound kunye ne-formula HN (CH2CH2OH)2. I-diethanolamine ecocekileyo yinto eqinileyo emhlophe kwiqondo lobushushu begumbi, kodwa imikhwa yayo yokufunxa amanzi kunye ne-supercool ithetha ukuba ihlala idibana njengolwelo olungenambala, olubonakalayo. I-Diethanolamine i-polyfunctional, i-amine yesibini kunye ne-diol. Njengezinye i-amines eziphilayo, i-diethanolamine isebenza njengesiseko esibuthathaka. Ukubonakalisa umlingiswa we-hydrophilic we-amine yesibini kunye namaqela e-hydroxyl, i-DEA iyanyibilika emanzini. I-Amides elungiselelwe ukusuka kwi-DEA ihlala i-hydrophilic. Kwi-2013, ikhemikhali yahlelwa yi-Arhente yeZizwe ngezizwe yoPhando lweCancer ngokuthi "kunokwenzeka ukuba i-carcinogenic ebantwini".

Isicelo
| Izinto ezifunxa irhasi yeasidi, izinto ezingeyo-ionic, izinto zokuthambisa, izinto zokuthambisa, izicoci zerhasi yamashishini, izithambisi. |
I-Diethanolamine isetyenziselwa ulwelo lwesinyithi ukusika, ukunyathela kunye nokusebenza ngokufa njenge-corrosion inhibitor. Kwimveliso yokucoca, izicoci, izinyibilikisi zelaphu kunye nolwelo lwesinyithi, i-diethanolamine isetyenziselwa ukungathathi hlangothi kwe-asidi kunye nokubekwa komhlaba. I-DEA yinto enokwenzeka yokucaphukisa ulusu kubasebenzi abavezwa kukuvezwa kulwelo olusekwe emanzini. Olunye uphononongo lubonise ukuba i-DEA iyakunqanda kwiimpuku zosana ukufunxwa kwe-choline, eyimfuneko kuphuhliso lobuchopho kunye nokugcinwa; amanqanaba "ayengaphantsi kakhulu kwezo zigxininiso ezinxulumene nokuphuhliswa kwengqondo ephazamisekileyo kwimouse" .Kuphononongo lwemouse lokubonakaliswa okungapheliyo kwi-DEA ephefumulayo kwiindawo eziphezulu (ngaphezu kwe-150 mg / m3), i-DEA yafunyanwa ukuba ibangele utshintsho lomzimba kunye nomzimba womzimba, utshintsho lwezonyango kunye ne-histopathological, ebonisa igazi elincinci, isibindi, izintso kunye ne-testicular systemic toxicity.
I-DEA iyinto enokucaphukisa ulusu kubasebenzi abavezwa kukuvezwa kulwelo olusekwe emanzini.Olunye uphando lubonise ukuba i-DEA inqanda kwiimpuku zosana ukufunxwa kwe-choline, eyimfuneko ekuphuhlisweni nasekugcinweni kwengqondo;[8] nangona kunjalo, isifundo ebantwini. ufumanise ukuba unyango lwe-dermal lwenyanga ye-1 kunye ne-lotion yesikhumba ekhoyo ngokurhweba equlethe i-DEA ibangele amanqanaba e-DEA "ayengaphantsi kakhulu kwezo zigxininiso ezinxulumene nokuphuhliswa kwengqondo ephazamisekileyo kwi-mouse". Kuphononongo lwegundane lokuvezwa okungapheliyo kwi-DEA ephefumlelweyo kwiindawo eziphezulu (ngaphezu kwe-150 mg / m3), i-DEA yafunyanwa ukuba ibangele utshintsho lomzimba kunye nomzimba, utshintsho lweklinikhi kunye ne-histopathological, ebonisa igazi elincinci, isibindi, izintso kunye ne-testicular systemic toxicity. Uphononongo luka-2009 lwafumanisa ukuba i-DEA ineempawu ezinobungozi, ezingapheliyo kunye ne-subchronic yetyhefu kwiintlobo zasemanzini.
Inzuzo
Umgangatho wemveliso, ubungakanani obaneleyo, unikezelo olusebenzayo, umgangatho ophezulu wenkonzo Inenzuzo ngaphezu kwe-amine efanayo, i-ethanolamine, ekubeni i-concentration ephezulu ingasetyenziselwa ukubola okufanayo. Oku kuvumela abasulungeki ukuba bakhuhle ihydrogen sulfide ngesantya esisezantsi se-amine esijikelezayo sisebenzisa amandla angaphantsi ngokubanzi.
