Tetraethylenepentamine CAS No 112-57-2
Ibisobanuro ku bicuruzwa
Diethanolamine, ikunze kwitwa DEA cyangwa DEOA, ni ifumbire mvaruganda hamwe na formula HN (CH2CH2OH) 2. Diethanolamine isukuye nikintu cyera cyane mubushyuhe bwicyumba, ariko ikunda gufata amazi hamwe na supercool bivuze ko ikunze guhura nkamazi adafite ibara, yuzuye amabara. Diethanolamine ni imikorere myinshi, kuba amine ya kabiri na diol. Kimwe nandi amine kama, diethanolamine ikora nkibanze ridakomeye. Kugaragaza imiterere ya hydrophilique ya amine ya kabiri ya amine na hydroxyl, DEA irashonga mumazi. Amide yateguwe kuva DEA akenshi nayo ni hydrophilique. Mu mwaka wa 2013, imiti yashyizwe mu rwego n’ikigo mpuzamahanga gishinzwe ubushakashatsi kuri kanseri "ishobora kuba kanseri ku bantu".

Gusaba
| Ahanini ikoreshwa muri synthesis ya polyamide resin, cation yo guhanahana cation, amavuta yo kwisiga amavuta, inyongeramusaruro yamavuta, nibindi, irashobora kandi gukoreshwa nka epoxy resin ikiza imiti, yihuta ya rubber. |
Diethanolamine ikoreshwa mumazi yo gukora ibyuma mugukata, gutera kashe no gupfa-nkibikoresho byangiza. Mu gukora ibikoresho byo kumesa, gusukura, gushiramo imyenda hamwe namazi yo gukora ibyuma, diethanolamine ikoreshwa mugutabuza aside no guta ubutaka. DEA ni uruhu rushobora kurakaza abakozi bakanguriwe no guhura n'amazi ashingiye kumazi. Ubushakashatsi bumwe bwerekanye ko DEA ibuza imbeba z’abana kwinjiza choline, ikenerwa mu mikurire y’ubwonko no kuyitaho; urwego "rwari munsi yibyo bitekerezo bifitanye isano niterambere ryubwonko bwangiritse mu mbeba" .Mu bushakashatsi bwakozwe nimbeba bwerekeranye no guhura na DEA ihumeka cyane (hejuru ya mg / m3 150), DEA yasanze itera uburemere bwumubiri ningingo, impinduka zamavuriro na histopathologique, byerekana amaraso yoroheje, umwijima, impyiko nuburozi bwa sisitemu.
DEA ishobora gutera uruhu kubakozi bakangurirwa no guhura n’amazi ashingiye ku mazi. Ubushakashatsi bumwe bwerekanye ko DEA ibuza imbeba z’abana kwinjiza choline, ikenewe mu mikurire y’ubwonko no kuyitaho; [8] ariko, ubushakashatsi bwakozwe ku bantu yemeje ko kuvura dermal ukwezi 1 hamwe na lisansi yuruhu iboneka mubucuruzi irimo DEA byatumye urwego rwa DEA "ruri munsi yibyo bitekerezo bifitanye isano no gukura kwubwonko bwangiza imbeba". Mu bushakashatsi bwimbeba bwerekeranye no guhura na DEA ihumeka cyane (hejuru ya mg / m3 150), DEA yasanze itera uburemere bwumubiri ningingo, ihinduka ryamavuriro na histopathologique, byerekana amaraso yoroheje, umwijima, impyiko nuburozi bwa sisitemu. Ubushakashatsi bwakozwe mu 2009 bwerekanye ko DEA ifite uburozi bukabije, budakira ndetse n’ubumara bw’amoko y’amazi

Ubwiza bwibicuruzwa, ubwinshi buhagije, gutanga neza, serivisi nziza Bifite inyungu kurenza amine, Ethanolamine, muburyo bwo kwibanda cyane bishobora gukoreshwa muburyo bumwe bwo kwangirika. Ibi bituma abayinonosora bashakisha hydrogène sulfide ku gipimo cyo hasi cya amine ikoresheje ingufu nke muri rusange.
