I-Triethanolamine I-Triethanolamine yaziwa nangokuthi ama-amine amathathu ayisisekelo kanye ne-triethanol. Iwuketshezi olunamafutha olungenambala olunephunga le-ammonia. Imunca amanzi kalula futhi iphenduke insundu uma ivezwa emoyeni noma ivezwa ekukhanyeni. Iba yikristalu eliyi-cubic elingenambala noma elikhanyayo emazingeni okushisa aphansi.

Izakhiwo zamakhemikhali:

Luwuketshezi olungenambala, olubonakalayo noluqinile ekushiseni kwegumbi. Luyi-hygroscopic, lunephunga le-ammonia, luyi-alkaline, futhi luyacasula. Iphuzu lokuncibilika lingu-21.2℃, iphuzu lokubila lingu-360℃, iphuzu lokushelela lingu-193℃, i-Chemicalbook relative density (d420) ingu-1.1242, kanti i-refractive index (nD20) ingu-1.4852. Luxubene emanzini, i-ethanol kanye ne-acetone, luncibilika kancane ku-ether, i-benzene kanye ne-carbon tetrachloride.

Inhloso:

Isetshenziswa njengoketshezi oluhlanzekile lokususa i-carbon dioxide noma i-hydrogen sulfide egesini. Ama-ester akhiwe phakathi kwe-triethanolamine nama-fatty acid aphezulu asetshenziswa kabanzi njenge-detergents, ama-emulsifiers, ama-humectants kanye nama-lubricant, futhi asetshenziswa nasekulungiseleleni ama-cosmetic balms. I-Triethanolamine isetshenziswa futhi njenge-preservative, i-ejenti yokuvimbela amanzi, i-analytical reagent, kanye ne-solvent. Ingasetshenziswa njenge-activator eku-polymerization kwerabha ye-nitrile, futhi ingasetshenziswa njenge-emulsifier kanye ne-stabilizer yamafutha nama-waxes, kanye ne-softener yezindwangu ngaphansi kwezimo ze-acidic. Ingenye yezingxenye zamafutha okuphotha e-polyester kanye neminye imicu yokwenziwa.

indlela yokukhiqiza

Kuwukufaka i-ethylene oxide kanye namanzi e-ammonia ku-reactor, futhi kwenze ukusabela kokujiya ekushiseni kokusabela okungu-30-40°C kanye nokucindezela kokusabela okungu-70.9-304kPa ukuze kukhiqizwe isisombululo esixubile se-mono-, di-, kanye ne-triethanolamine, esishiswa ku-90-120°C. Ngemva kokuphelelwa amanzi emzimbeni kanye nokuhlushwa, ithunyelwa emibhoshongweni emithathu ye-vacuum Chemicalbook distillation ukuze kuhlikihlwe i-vacuum. Izingxenyana zibanjwa ngokwezindawo ezahlukene zokubilisa ukuze kutholakale imikhiqizo eqediwe ye-monoethanolamine, i-diethanolamine kanye ne-triethanolamine enobumsulwa obungu-99%. Ngesikhathi senqubo yokusabela, uma ingxenye ye-ethylene oxide ikhushulwa, isilinganiso sokukhiqiza se-di- kanye ne-triethanolamine sizokhula, okungakhulisa isivuno se-di- kanye ne-triethanolamine.
