I-Tetraethylenepentamine, ebizwa nangokuthi i-tritetraethylenediamine, noma i-TEPA, iwuketshezi oluphuzi noma olubomvu olunezinhlanganisela eziningi olunesakhiwo esisodwa. Luncibilika kalula emanzini, i-ethyl alcohol, kanye ne-solvent eningi yezinto eziphilayo, kodwa aluncibiliki ku-benzene kanye ne-quintessence. Le angle yehora elihlanganisiwe inamandla okumunca amanzi kanye ne-carbon dioxide emoyeni, okwenza kube yi-alkaline ngokwemvelo. I-TEPA ivame ukusetshenziswa ekusetshenzisweni okuhlukahlukene njengesixazululo se-gas chromatography esimile sokugcina nokuhlukanisa izinto ezahlukene ezifana notshwala, i-amine, i-pyridine, i-quinoline, i-piperazine, i-thiols, kanye namanzi. Iphinde isetshenziswe ku-anion exchange resin, i-lubricate oil additive, i-fuel oil additive, futhi isebenza njenge-epoxy resin hardening agent kanye ne-raber vulcanization accelerators.

Inhloso:Ukutholwa kwe-tetraethylenepentamine kusetshenziswa kwayo ekulinganisweni okuyinkimbinkimbi kwezinto zensimbi ezifana nethusi, i-zinc, kanye nokuxhashazwa kwe-nickel njengendlela yamanje yokugcina. Iphinde isetshenziswe ekuhlanganisweni kwezinto ezine-acidic, ekuhlanzweni kwegesi, ejenti yokuphelelwa amanzi emzimbeni, enjoloba yokwenziwa, kanye nokusetshenziswa kwe-resin. Ngaphezu kwalokho, i-TEPA isetshenziswa njengesengezo, i-ejenti yokuqinisa, kanye ne-accelerator ezimbonini ezahlukahlukene.

Ukukhiqizwa kwe-tetraethylenepentamine kuhilela izitebhisi eziningi futhi kuyimpahla ye-carbon monoxide ye-ethylenediamine, i-diethylenetriamine, i-triethylenetetramine, ne-polyethylenepolyamine. Indlela yokukhiqiza ifaka phakathi i-thermal amination kanye ne-ammonolysis chemical reaction, i-neutralization, kanye ne-distillation ngaphansi kwengcindezi yokunciphisa. Inqubo yokucwenga ihilela ukuphelelwa amanzi emzimbeni, ukuhlukaniswa ngaphansi kwengcindezi yokunciphisa, kanye nokuphinda kusetshenziswe ukuze kutholakale i-tetraethylenepentamine hydrochloride emsulwa. Ngesisindo sama-molecule esingu-189.3 kanye nenombolo ye-calcium 112-57-2, i-engeli yehora le-TEPA iphuzu lokubila elingu-340 ° degree centigrade, ubuningi obungu-0.998g / milliliter ku-25 ° degree centigrade, kanye nephuzu lokukhanya elingu-365 ° F.

ukuqondaizindaba zebhizinisiKubalulekile kubatshalizimali, osomabhizinisi, kanye nochwepheshe embonini ehlukahlukene. Ngokuhlala unolwazi mayelana nokuthambekela kwemakethe, inkomba yezomnotho, kanye nokuvuselelwa kwenkampani, umuntu angakwazi ukwenza isinqumo esinolwazi mayelana nokutshalwa kwezimali, ubambiswano, kanye nohlelo lwebhizinisi. Hlaziya idatha, ubikezele ukunyakaza kwemakethe, futhi uqonde umthelela womcimbi womhlaba wonke ebhizinisini kungasiza umuntu ukuthi ahambe ngendlela efanele endaweni yamandla okuziphatha yomhlaba webhizinisi. Hlala uvuselelwa ngentuthuko yakamuva ezindabeni zebhizinisi ukuze uhlale uphambili endaweni yemakethe yokuncintisana.
