Ko te nama CAS o te triethylenetetramine he 112-24-3, ko te tauira ngota ko C6H18N4, a he wai kowhai marama me te kaha taketake me te pokey reo.I tua atu i te whakamahi hei whakarewa, ka whakamahia ano te triethylenetetramine i roto i te hanga i nga kaipakihi epoxy resin, nga kaihoko chelating whakarewa, me nga kapia polyamide waihanga me nga kapia whakawhiti katote.

āhuatanga kikokiko
Ko te wai kowhai kawakore me te wai kowhai ngawari, he iti ake te pähekeheke i to te diethylenetriamine, engari he rite tonu ona ahuatanga.Te ira koropuha 266-267°C (272°C), 157°C (2.67kPa), te mīti 12°C, te kiato whanaunga (20, 20°C) 0.9818, te taupū whakaata (nD20) 1.4971, te uira 143°C , ira mura-aunoa 338°C.Wairewa i roto i te wai me te waiwaro, paku wairewa i roto i te etera.He mura ahi.He iti te pähekeheke, te kaha hygroscopicity me te kaha kawakore.Ka taea te tango hau hau.Ka wera, ka tupono ka wera ina pa ana ki nga mura ahi me te wera.He tino pirau, ka taea te whakaihiihi i te kiri me nga kiriuhi mucous, nga kanohi me te waahanga manawa, me te mate mate kiri, te mate huango me etahi atu tohu.

āhuatanga matū
Hua ngingiha (decomposition): tae atu ki te waikura hauota paitini.

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

Alkali Kaha: Ka tauhohe ki te pa ki nga waikura kaha, ka puta he ahi me te pahūtanga.Ka tauhohe i te pa atu ki nga pūhui hauota me te waiwaro maota.Ka tauhohe ki te waikawa.He hotokore ki nga pūhui amino, isocyanates, alkenyl oxides, epichlorohydrin, aldehydes, waipiro, ethylene glycol, phenols, cresols, me nga otinga caprolactam.Ka tauhohe ki te nitrocellulose.He hotokore hoki ki te acrolein, acrylonitrile, tert-butyl nitroacetylene, ethylene oxide, isopropyl chloroformate, maleic anhydride, me te triisobutyl aluminum.Ka waikura te parahi, te koranu parahi, te cobalt me ​​te nickel.

Whakamahi
1. Whakamahia hei kaihoko whakamaora i te pāmahana rūma mo te kapia epoxy;

2. Ka whakamahia hei whakahiato waro, hei takawaenga waikano me nga whakarewa;

3. Whakamahia i roto i te hanga o te polyamide resins, katote whakawhiti resins, surfactants, lubricant additives, hau purifiers, etc.;

4. I whakamahia hei kaihoko chelating whakarewa, cyanide-free electroplating diffusing agent, rapa awhina, kanapa, hopii, dispersing agent, etc.;

5. Ka whakamahia hei kaihoko whakahiato, hei kaihoko whakamaoritanga mo te hau kawakore, he kaihoko whakaoti papanga me nga mea mata waihanga mo te kapia whakawhiti katote me te kapia polyamide;

6. Ka whakamahia hei kaikawe vulcanizing mo te fluororubber.

Tikanga whakaputa
Ko tana tikanga whakaputa ko te tikanga amination dichloroethane.Ko te 1,2-dichloroethane me te wai haukini i tukuna ki roto i te reactor tubular mo te haukini wera-wera i te mahana o te 150-250 °C me te pehanga 392.3 kPa.Ko te otinga tauhohenga ka whakakorehia ki te kawakore ki te whiwhi amine kore utu, ka kukū hei tango i te konutai pūhaumāota, kātahi ka marewa te hua masivesivá i raro i te pehanga iti, me te hautanga i waenga i te 195-215° C. ka haukotia kia whiwhi i te hua kua oti.Ko tenei tikanga ka whakaputa tahi i te ethylenediamine i te wa kotahi;diethylenetriamine;tetraethylenepentamine me te polyethylenepolyamine, ka taea te tiki ma te whakahaere i te pāmahana o te pourewa whakatika hei whakamarumaru i te ranunga amine, me te haukoti i nga hautau rereke mo te wehenga.
