Nambala ya CAS ya triethylenetetramine ndi 112-24-3, mawonekedwe a molekyulu ndi C6H18N4, ndipo ndi madzi achikasu opepuka okhala ndi maziko amphamvu komanso ma viscosity apakatikati.Kuphatikiza pa kugwiritsidwa ntchito ngati zosungunulira, triethylenetetramine imagwiritsidwanso ntchito popanga ma epoxy resin curring agents, metal chelating agents, ndi synthetic polyamide resins ndi ion exchange resins.

katundu wakuthupi
Zamadzi zamchere zamchere komanso zachikasu zowoneka bwino, kusakhazikika kwake ndikotsika kuposa kwa diethylenetriamine, koma katundu wake ndi wofanana.Malo otentha 266-267°C (272°C), 157°C (2.67kPa), kuzizira 12°C, kachulukidwe wachibale (20, 20°C) 0.9818, refractive index (nD20) 1.4971, flash point 143°C , poyatsira moto 338°C.Kusungunuka m'madzi ndi ethanol, kusungunuka pang'ono mu ether.Zoyaka.Kusakhazikika kochepa, kulimba kwa hygroscopicity ndi zamchere wamphamvu.Imatha kuyamwa mpweya woipa mumlengalenga.Zoyaka, zimakhala ndi chiopsezo choyaka moto zikayatsidwa ndi malawi otseguka ndi kutentha.Zimakhala zowononga kwambiri ndipo zimatha kuyambitsa khungu ndi mucous nembanemba, maso ndi kupuma kwapakhungu, komanso kumayambitsa ziwengo pakhungu, mphumu ya bronchial ndi zizindikiro zina.

mankhwala katundu
Kuyaka (kuwola) mankhwala: kuphatikizapo poizoni nayitrogeni oxides.

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

Alkali wamphamvu: Imachita itakumana ndi zotulutsa zamphamvu, kuchititsa ngozi yamoto ndi kuphulika.Imakhudzidwa ikakumana ndi nitrogen kompositi ndi ma chlorinated hydrocarbons.Amachita ndi asidi.Zosagwirizana ndi amino mankhwala, isocyanates, alkenyl oxides, epichlorohydrin, aldehydes, alcohols, ethylene glycol, phenols, cresols, ndi caprolactam solutions.Imakhudzidwa ndi nitrocellulose.Zimakhalanso zosagwirizana ndi acrolein, acrylonitrile, tert-butyl nitroacetylene, ethylene oxide, isopropyl chloroformate, maleic anhydride, ndi triisobutyl aluminium.Amawononga cobalt, nickel, cobalt ndi aloyi zamkuwa.

Gwiritsani ntchito
1. Amagwiritsidwa ntchito ngati chipinda chochizira kutentha kwa epoxy resin;

2. Ntchito ngati organic kaphatikizidwe, utoto intermediates ndi solvents;

3. Amagwiritsidwa ntchito popanga polyamide resins, ion exchange resins, surfactants, lubricant additives, oyeretsa gasi, ndi zina zotero;

4. Ntchito ngati zitsulo chelating wothandizira, cyanide-free electroplating diffusing agent, mphira wothandiza, kuwala wothandizila, detergent, dispersing wothandizira, etc.;

5. Amagwiritsidwa ntchito ngati complectoring agent, dehydrating agent for alkaline gasi, fabric finishing agent and synthetic raw for ion exchanger resin ndi polyamide resin;

6. Amagwiritsidwa ntchito ngati vulcanizing wothandizira pa fluororubber.

Njira yopangira
Njira yake yopangira ndi dichloroethane amination njira.Madzi a 1,2-dichloroethane ndi ammonia adatumizidwa mu chubu cha tubular kuti apange ammoniation yotentha pa kutentha kwa 150-250 ° C ndi kuthamanga kwa 392.3 kPa.The reaction solution is neutralized with alkali to find mixed free amine, that is concentrated to remove sodium chloride, ndiye zosakayikitsa ndi distilled pansi pa kupsyinjika kuchepetsedwa, ndi kachigawo pakati pa 195-215 ° C. ndi intercepted kupeza chomalizidwa.Njira imeneyi nthawi imodzi imapanga ethylenediamine;diethylenetriamine;tetraethylenepentamine ndi polyethylenepolyamine, amene angapezeke mwa kulamulira kutentha kwa rectifying nsanja kuti distill ndi amine osakaniza, ndi intercepting tizigawo siyana kwa kulekana.
