Inombolo ye-CAS ye-triethylenetetramine ngu-112-24-3, ifomula ye-molecular C6H18N4, futhi iwuketshezi oluphuzi olukhanyayo olunosisekelo oluqinile kanye ne-viscosity ephakathi. Ngaphezu kokusetshenziswa njengesinyibilikisi, i-triethylenetetramine iphinde isetshenziswe ekwenzeni ama-epoxy resin elaphayo, ama-metal chelating agents, nama-synthetic polyamide resins nama-ion exchange resins.

izakhiwo zomzimba
I-alkaline enamandla kanye noketshezi oluphuzi olune-viscous ngokumaphakathi, ukuguquguquka kwayo kuphansi kune-diethylenetriamine, kodwa izakhiwo zayo ziyefana. Iphuzu elibilayo lingu-266-267°C (272°C), 157°C (2.67kPa), iphoyinti eliqandayo ngu-12°C, ukuminyana kwesihlobo (20, 20°C) 0.9818, inkomba ye-refractive (nD20) 1.4971, iphoyinti elikhanyayo ngu-143°C , iphoyinti lokuzifudumeza elingu-338°C. Incibilika emanzini ne-ethanol, inyibilika kancane ku-ether. Okuvutha umlilo. I-volatility ephansi, i-hygroscopicity eqinile kanye ne-alkaline eqinile. Ingakwazi ukumunca i-carbon dioxide emoyeni. Ukuvutha, kunobungozi bokusha lapho kuvezwe amalangabi avulekile nokushisa. Igqwala kakhulu futhi ingashukumisa isikhumba nolwelwesi lwamafinyila, amehlo kanye nomgudu wokuphefumula, futhi ibangele ukungezwani komzimba nesikhumba, isifuba somoya we-bronchial nezinye izimpawu.

izakhiwo zamakhemikhali
Imikhiqizo evuthayo (ukubola): kufaka phakathi ama-nitrogen oxide anobuthi.

Contraindications: acrolein, acrylonitrile, tert-butyl nitroacetylene, ethylene oxide, isopropyl chloroformate, anhydride maleic, triisobutyl aluminium.

I-alkali Eqinile: Isabela lapho ithintana nama-oxidants aqinile, ibangele ingozi yomlilo nokuqhuma. Isabela ngokuthintana nezinhlanganisela ze-nitrogen nama-hydrocarbons ane-chlorine. Isabela nge-asidi. Akuhambisani nama-amino compounds, isocyanates, alkenyl oxides, epichlorohydrin, aldehydes, alcohols, ethylene glycol, phenols, cresols, nezixazululo ze-caprolactam. Isabela nge-nitrocellulose. Futhi ayihambisani ne-acrolein, i-acrylonitrile, i-tert-butyl nitroacetylene, i-ethylene oxide, i-isopropyl chloroformate, i-anhydride yamaleic, ne-triisobutyl aluminium. I-corrodes ithusi, ama-alloys ethusi, i-cobalt ne-nickel.

Sebenzisa
1. Isetshenziswa njenge-ejenti yokwelapha izinga lokushisa legumbi le-epoxy resin;

2. Isetshenziswa njenge-organic synthesis, i-dyes intermediates kanye nezincibilikisi;

3. Isetshenziswa ekwenzeni ama-polyamide resins, ama-ion exchange resins, ama-surfactants, izithasiselo zokuthambisa, izihlanzi zegesi, njll.;

4. Isetshenziswa njenge-ejenti ye-metal chelating, i-ejenti yokusabalalisa i-cyanide-free electroplating, insiza yerabha, i-ejenti ekhanyayo, okokuhlanza, i-ejenti ehlakazayo, njll.;

5. Isetshenziswa njenge-ejenti eyinkimbinkimbi, i-ejenti eqeda amanzi emzimbeni ngegesi ye-alkali, i-ejenti yokuqedela indwangu kanye nezinto zokwenziwa zokwenziwa ze-ion exchanger resin ne-polyamide resin;

6. Isetshenziswa njenge-ejenti ye-vulcanizing ye-fluororubber.

Indlela yokukhiqiza
Indlela yayo yokukhiqiza i-dichloroethane amination method. Amanzi ayi-1,2-dichloroethane kanye ne-ammonia athunyelwe ku-reactor ye-tubular ukuze athole i-ammoniation yokucindezela okushisayo ezingeni lokushisa elingu-150-250 °C kanye nengcindezi engu-392.3 kPa. Isixazululo sokusabela siyancishiswa nge-alkali ukuze kutholwe i-amine yamahhala exubile, egxilwa ukuze isuse i-sodium chloride, bese umkhiqizo ongahluziwe uhlanjululwa ngaphansi kwengcindezi encishisiwe, bese ingxenye ephakathi kuka-195-215 ° C. inqanyulwa ukuze kutholwe umkhiqizo oqediwe. Le ndlela kanyekanye ikhiqiza i-ethylenediamine; i-diethylenetriamine; i-tetraethylenepentamine kanye ne-polyethylenepolyamine, engatholwa ngokulawula izinga lokushisa lombhoshongo olungisayo ukuze uhlanganise ingxube ye-amine, futhi unqamule izingxenyana ezihlukene zokuhlukaniswa.
