Imikhiqizo
I-Tetraethylenepentamine CAS No. 112-57-2
Incazelo Yomkhiqizo
I-Diethanolamine, evame ukufushaniswa njenge-DEA noma i-DEOA, iyinhlanganisela yezinto eziphilayo enefomula ethi HN(CH2CH2OH)2. I-diethanolamine ehlanzekile iqinile emhlophe ezingeni lokushisa lasekamelweni, kodwa ukuthambekela kwayo kokumunca amanzi kanye ne-supercool okusho ukuthi ivame ukuhlangana nayo njengoketshezi olungenambala, olubonakalayo. I-Diethanolamine i-polyfunctional, iyi-amine yesibili ne-diol. Njengamanye ama-amine aphilayo, i-diethanolamine isebenza njengesisekelo esibuthakathaka. Ibonisa uhlamvu lwe-hydrophilic lweqembu lesibili le-amine ne-hydroxyl, i-DEA iyancibilika emanzini. Ama-Amide alungiselelwe kusuka ku-DEA ngokuvamile nawo ane-hydrophilic. Ngo-2013, ikhemikhali yahlukaniswa yi-International Agency for Research on Cancer ngokuthi "mhlawumbe i-carcinogenic kubantu".

Isicelo
| Isetshenziswa kakhulu ekuhlanganiseni i-polyamide resin, i-cation exchange resin, izithasiselo zikawoyela wokugcoba, izithasiselo zikawoyela kaphethiloli, njll., futhi ingasetshenziswa njenge-epoxy resin elaphayo, i-rubber vulcanization accelerator. |
I-Diethanolamine isetshenziswa oketshezini lwensimbi ukusika, ukugxiviza kanye nokusebenza kokufa njenge-corrosion inhibitor. Lapho kukhiqizwa izinto zokuhlanza, zokuhlanza, izincibilikisi zendwangu kanye noketshezi lwensimbi, i-diethanolamine isetshenziselwa ukungathathi hlangothi kwe-asidi nokufaka inhlabathi. I-DEA iyisithukuthezi esingaba khona esikhumbeni ezisebenzini ezizwela ngokuchayeka kuketshezi lwensimbi olusekelwe emanzini. Olunye ucwaningo lwabonisa ukuthi i-DEA ivimbela ezinganeni zamagundane ukumuncwa kwe-choline, okudingekayo ekuthuthukisweni nasekugcinweni kobuchopho;[8] nokho, ucwaningo kubantu lwathola ukuthi ukwelashwa kwesikhumba inyanga engu-1 ngesigcobo sesikhumba esitholakalayo esithengiswayo esiqukethe i-DEA kwaholela ku-DEA. amazinga "ayengaphansi kakhulu kwalokho okugxilile okuhlotshaniswa nokuthuthukiswa kobuchopho okuphazamisekile egundaneni".Ocwaningweni lwegundane lokuchayeka okungamahlalakhona ku-DEA ehogeliwe ekugxilweni okuphezulu (ngaphezu kuka-150 mg/m3), i-DEA yatholakala yenza izinguquko zesisindo somzimba nesitho, izinguquko zomtholampilo kanye ne-histopathological, ezibonisa igazi elincane, isibindi, izinso kanye nobuthi be-testicular systemic.
I-DEA inamandla okucasula isikhumba ezisebenzini eziqwashiswa ngokuchayeka oketshezini lwensimbi olusekelwe emanzini.Olunye ucwaningo lwabonisa ukuthi i-DEA ivimbela kumagundane ezingane ukumuncwa kwe-choline, okudingekayo ekuthuthukiseni nasekulondolozeni ubuchopho;[8] nokho, ucwaningo kubantu. inqume ukuthi ukwelashwa kwesikhumba inyanga engu-1 ngesigcobo sesikhumba esitholakalayo esithengiswayo esiqukethe i-DEA kubangele amazinga e-DEA "ayengaphansi kakhulu kwalokho kugxilile okuhlobene nokukhula kobuchopho okuphazamisekile egundaneni". Ocwaningweni lwegundane lokuchayeka okungamahlalakhona ku-DEA ehogeliwe ekugxilweni okuphezulu (ngaphezulu kwe-150 mg/m3), i-DEA yatholakala yenza izinguquko zesisindo somzimba nesitho, izinguquko zomtholampilo neze-histopathological, ezibonisa igazi elincane, isibindi, izinso kanye nobuthi be-testicular systemic. Ucwaningo lwango-2009 lwathola ukuthi i-DEA inezindawo ezinobuthi obunamandla, obungapheli kanye nobuncane bezinhlobo zasemanzini.
Inzuzo
Izinga lomkhiqizo, inani elanele, ukulethwa okuphumelelayo, izinga eliphezulu lesevisi Inenzuzo kune-amine efanayo, i-ethanolamine, ngokuthi ukugxilisa okuphezulu kungase kusetshenziselwe amandla afanayo okugqwala. Lokhu kuvumela abacwengi ukuthi bakhuhle i-hydrogen sulfide ngenani eliphansi le-amine elijikelezayo ngokusetshenziswa kwamandla sekukonke.
