I-Tetraethylenepentamine, ekwabizwa ngokuba yi-tritetraethylenediamine, okanye i-TEPA, lulwelo olutyheli okanye olubomvu-orenji oluneempawu ezahlukeneyo. Lunyibilika lula emanzini, kwi-ethyl alcohol, nakwi-organic solvent eninzi, kodwa alunyibiliki kwi-benzene nakwi-quintessence. Olu hlobo lwe-hour angle lunamandla okufunxa amanzi kunye ne-carbon dioxide emoyeni, luyila i-alkaline ngokwemvelo. I-TEPA isetyenziswa rhoqo kwizicelo ezahlukeneyo ezifana nesisombululo se-gas chromatography esisisigxina sokugcina nokwahlulahlula izinto ezahlukeneyo ezifana notywala, i-amine, i-pyridine, i-quinoline, i-piperazine, i-thiols, kunye namanzi. Ikwasetyenziswa kwi-anion exchange resin, kwi-lubricate oil additive, kwi-fuel oil additive, kwaye isebenza njenge-epoxy resin hardening agent kunye ne-rubber vulcanization accelerators.

Injongo:Ukufunyanwa kweTetraethylenepentamine kusetyenziswe kakhulu kwi-titration ye-metallic element efana ne-copper, i-zinc, kunye ne-nickel, indlela yangoku yokuphuma kwe-end point. Ikwasetyenziswa kwi-saponification ye-acidity substance, ukucocwa kwegesi, i-dehydration agent, i-synthetic rubber, kunye ne-resin application. Ukongeza, i-TEPA isetyenziswa njenge-additive, i-hardening agent, kunye ne-accelerator kwimizi-mveliso eyahlukeneyo.

Ukuveliswa kwe-tetraethylenepentamine kubandakanya izitebhisi ezininzi kwaye yi-carbon monoxide-merchandise ye-ethylenediamine, i-diethylenetriamine, i-triethylenetetramine, kunye ne-polyethylenepolyamine. Indlela yokuvelisa ibandakanya i-thermal amination kunye ne-ammonolysis chemical reaction, i-neutralization, kunye ne-distillation phantsi koxinzelelo lokunciphisa. Inkqubo yokucoca ibandakanya ukuphelelwa ngamanzi emzimbeni, ukwahlulwahlulwa phantsi koxinzelelo lokunciphisa, kunye ne-recrystallization ukuze kufunyanwe i-tetraethylenepentamine hydrochloride ecocekileyo. Ngobunzima be-molecular ye-189.3 kunye nenombolo ye-calcium 112-57-2, i-TEPA hour angle inendawo yokubilisa ye-340 ° degree centigrade, uxinano lwe-0.998g / milliliter kwi-25 ° degree centigrade, kunye ne-flash point ye-365 ° F.

ukuqondaiindaba zoshishinoKubalulekile kubatyali-mali, usomashishini, kunye neengcali kushishino olwahlukeneyo. Ngokuhlala unolwazi malunga nokuthambekela kwimarike, isalathisi sezoqoqosho, kunye nohlaziyo lwenkampani, umntu unokuchonga isigqibo esinolwazi malunga nokutyala imali, intsebenziswano, kunye nesicwangciso seshishini. Ukuhlalutya idatha, ukuqikelela intshukumo yemarike, kunye nokuqonda impembelelo yesiganeko sehlabathi kwishishini kunokunceda umntu ukuba ahambe ngendlela efanelekileyo kwimeko yamandla okuziphatha yehlabathi leshishini. Hlala unolwazi ngophuhliso lwamva nje kwiindaba zeshishini ukuze uhlale uphambili kwimeko yemarike yokhuphiswano.
