ʻO ka helu CAS o triethylenetetramine he 112-24-3, ʻo ka molecular formula C6H18N4, a he wai melemele māmā me ke kumu ikaika a me ka viscosity medium.Ma waho aʻe o ka hoʻohana ʻana ma ke ʻano he solvent, hoʻohana pū ʻia ka triethylenetetramine i ka hana ʻana i nā mea hoʻōla epoxy resin, nā mea hoʻoheheʻe metala, a me nā resins polyamide synthetic a me nā resins exchange ion.

waiwai kino
ʻO ka wai melemele alkaline ikaika a me ka liʻiliʻi liʻiliʻi, ʻoi aku ka haʻahaʻa o kona volatility ma mua o ka diethylenetriamine, akā like kona mau waiwai.ʻO ka helu hoʻolapalapa 266-267°C (272°C), 157°C (2.67kPa), wahi hau hau 12°C, mānoanoa pili (20, 20°C) 0.9818, helu kuhikuhi (nD20) 1.4971, kiko uila 143°C , wahi ho'ā 'akomi 338°C.Hiki ke hoʻoheheʻe ʻia i ka wai a me ka ethanol, hiki ke hoʻoheheʻe ʻia i ka etera.Hiki ke ahi.Haʻahaʻa volatility, ikaika hygroscopicity a ikaika alkaline.Hiki ke komo i ke kalapona kalapona i ka lewa.Hiki ke puhi, aia ka pilikia o ke ahi ke ʻike ʻia i nā lapalapa a me ka wela.He mea ʻino loa ia a hiki ke hoʻoulu i ka ʻili a me ka mucous membranes, nā maka a me ka ʻōpū hanu, a hoʻoulu i ka ʻili allergies, bronchial asthma a me nā hōʻailona ʻē aʻe.

waiwai kemika
Nā huahana hoʻopau (decomposition): me nā oxide nitrogen toxic.

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

Alkali ikaika: Hoʻopili i ka pilina me nā mea hoʻoheheʻe ikaika, e hoʻopilikia i ke ahi a me ka pahū.Hoʻopili i ka pilina me nā pūhui nitrogen a me nā hydrocarbons chlorinated.Pane me ka waika.ʻAʻole kūpono me nā pūhui amino, isocyanates, alkenyl oxides, epichlorohydrin, aldehydes, alcohols, ethylene glycol, phenols, cresols, a me nā hopena caprolactam.Hoʻopili me ka nitrocellulose.ʻAʻole kūpono ia me ka acrolein, acrylonitrile, tert-butyl nitroacetylene, ethylene oxide, isopropyl chloroformate, maleic anhydride, a me triisobutyl aluminika.Hoʻopau i ke keleawe, nā ʻāpana keleawe, ka cobalt a me ka nickel.

Hoʻohana
1. Hoʻohana ʻia ma ke ʻano he mea ho'ōla wela lumi no ka resin epoxy;

2. Hoʻohana ʻia e like me ka synthesis organik, nā mea hoʻonaninani a me nā solvents;

3. Hoʻohana ʻia i ka hana ʻana i nā resins polyamide, nā resins exchange ion, surfactants, lubricant additives, gas purifiers, etc.;

4. Hoʻohana 'ia e like me ka metala chelating agent, cyanide-free electroplating diffusing agent, rubber auxiliary, brightening agent, detergent, dispersing agent, etc.;

5. Hoʻohana ʻia ma ke ʻano he mea paʻakikī, mea hoʻomaʻemaʻe wai no ke kinoea alkaline, mea hoʻopau lole a me nā mea synthetic no ka resin exchanger a me ka resin polyamide;

6. Hoʻohana ʻia ma ke ʻano he vulcanizing agent no ka fluororubber.

Hana hana
ʻO kāna hana hana ʻo dichloroethane amination method.Ua hoʻouna ʻia ka 1,2-dichloroethane a me ka wai amonia i loko o kahi reactor tubular no ka hoʻoulu ʻana i ka ammoniation wela ma kahi mahana o 150-250 °C a me kahi kaomi o 392.3 kPa.Hoʻopili ʻia ka hopena hopena me ka alkali no ka loaʻa ʻana o ka amine manuahi ʻole, i hoʻopaʻa ʻia no ka wehe ʻana i ka sodium chloride, a laila hoʻoheheʻe ʻia ka huahana crude ma lalo o ke kaomi hoʻemi ʻia, a hoʻopaʻa ʻia ka hakina ma waena o 195-215 ° C. no ka loaʻa ʻana o ka huahana pau.Hoʻopuka pū kēia ʻano hana i ka ethylenediamine;diethylenetriamine;tetraethylenepentamine a me ka polyethylenepolyamine, hiki ke loaa ma ka hoomalu ana i ka wela o ka halekiai rectifying e distill i ka hui amine, a intercepting okoa hakina no ka hookaawale ana.
