Tetraethylenepentamine CAS No. 112-57-2
Product Description
Diethanolamine, rinowanzodimburirwa seDEA kana DEOA, musanganiswa weorganic une formula HN(CH2CH2OH)2. Pure diethanolamine ichena yakasimba patembiricha yekamuri, asi maitiro ayo ekutora mvura uye kune supercool zvichireva kuti inowanzosangana semvura isina ruvara, viscous. Diethanolamine is polyfunctional, iri yechipiri amine uye diol. Kufanana nemamwe organic amines, diethanolamine inoshanda senheyo isina simba. Kuratidzira hunhu hwehydrophilic hwechipiri amine uye hydroxyl mapoka, DEA inonyungudika mumvura. Amides akagadzirirwa kubva kuDEA anowanzo zvakare hydrophilic. Muna 2013, kemikari yakarongedzerwa neInternational Agency for Research on Cancer se "zvichida carcinogenic kuvanhu".

Application
| Inonyanya kushandiswa mukugadzirwa kwepolyamide resin, cation exchange resin, mafuta ekuwedzera ekuwedzera, mafuta ekuwedzera emafuta, nezvimwewo, anogona zvakare kushandiswa se epoxy resin kurapa mumiririri, rubber vulcanization accelerator. |
Diethanolamine inoshandiswa mumagetsi ekugadzira simbi yekucheka, kutsika uye kufa-casting mashandiro se corrosion inhibitor. Mukugadzirwa kwezvinosuka, zvinochenesa, zvinonyungudutsa machira uye zvinwiwa zvesimbi, diethanolamine inoshandiswa kuita acidization uye kuisa ivhu. DEA inogona kutsamwisa ganda muvashandi vanofemerwa nekusangana nemvura-based metalworking fluids. Imwe ongororo yakaratidza kuti DEA inhibisa mucheche mbeva kubatwa kwecholine, inodiwa pakukura kwehuropi nekugadzirisa;[8] zvisineyi, ongororo muvanhu yakaratidza kuti kurapwa kwedermal kwemwedzi we1 neinotengeswa yeganda lotion ine DEA yakakonzera DEA. mazinga aive "kure pasi pezviya zvekufunganya zvine chekuita nekukanganisika kwehuropi kukura mugonzo". Muchidzidzo chembeva chekugara kuratidzwa kweDEA yakafemerwa pamatunhu akakwirira (pamusoro pe150 mg/m3), DEA yakawanikwa ichikurudzira kushanduka kwehuremu hwemuviri nenhengo, kiriniki uye histopathological shanduko, zvinoratidza ropa rakapfava, chiropa, itsvo uye testicular systemic toxicity.
DEA inogona kutsamwisa ganda muvashandi vanonzwisiswa nekusangana nemvura-based metalworking fluids.Imwe ongororo yakaratidza kuti DEA inhibits mumwana wembeva kutorwa kwecholine, iyo inodiwa mukukura kweuropi nekugadzirisa;[8] zvisinei, chidzidzo muvanhu. yakateya kuti kurapwa kwedermal kwemwedzi we1 neinotengeswa yeganda lotion ine DEA yakakonzera mazinga eDEA aive "kure pasi peaya mafungidziro ane chekuita nekukanganisika kwehuropi kukura mugonzo". Muchidzidzo chembeva chekugara chisingaperi kune DEA yakafemerwa pamazinga akanyanya (pamusoro pe150 mg/m3), DEA yakawanikwa ichikurudzira uremu hwemuviri uye nhengo, shanduko yekiriniki uye histopathological, inoratidza ropa rakapfava, chiropa, itsvo uye testicular systemic toxicity. Chidzidzo che2009 chakawana kuti DEA ine mukana wakaoma, usingaperi uye subchronic toxicity zvimiro zvezvipenyu zvemumvura.
Advantage
Unhu hwechigadzirwa, huwandu hwakakwana, kuburitsa kunoshanda, mhando yepamusoro yebasa Iine bhenefiti pamusoro peamine yakafanana, ethanolamine, pakuti iyo yakakwira yekumisikidza inogona kushandiswa kune imwecheteyo ngura. Izvi zvinobvumira vanonatsa kukwesha hydrogen sulfide pamwero wakaderera wekutenderera amine nekushomeka kwesimba rose rekushandisa.
