Tetraethylenepentamine, yomwe imadziwikanso kuti tritetraethylenediamine, yomwe imafupikitsidwa kuti TEPA, ndi madzi okhuthala achikasu kapena ofiira ngati lalanje. Amasungunuka mosavuta m'madzi, ethanol ndi zinthu zambiri zachilengedwe, osasungunuka mu benzene ndi ether. Amayamwa mosavuta madzi ndi carbon dioxide mumlengalenga. Alkaline. Imapezeka mwa kutentha ndi ammonolysis reaction pakati pa dichloroethane ndi ammonia, kuletsa ndi alkali kenako n’kusungunuka pansi pa kupsinjika kochepa. Imagwiritsidwa ntchito ngati njira yothetsera mpweya wa chromatography kuti isungidwe bwino komanso kulekanitsa Chemicalbook ya alcohols, amines, pyridine, quinoline, piperazine, thiols ndi madzi. Imagwiritsidwa ntchito mu anion exchange resins, mafuta owonjezera, mafuta owonjezera, komanso imagwiritsidwa ntchito ngati epoxy resin curing agents, rabara vulcanization accelerators, ndi zina zotero.

Cholinga

:Tetraethylene pentamine ingagwiritsidwe ntchito pokonza mkuwa, zinc ndi nickel pogwiritsa ntchito njira yamakono, kusakaniza zinthu za acidic, mphira wopangidwa ndi resin komanso choyeretsera mpweya komanso chothandizira kutaya madzi m'thupi. Imagwiritsidwanso ntchito ngati zowonjezera, zochiritsira, zofulumizitsa, ndi zina zotero.

Njira yopangira:

Chogulitsachi ndi chopangidwa ndi ethylenediamine, diethylenetriamine, triethylenetetramine, ndi polyethylenepolyamine. Kuti mudziwe mfundo ndi ntchito zopangira, chonde onani ethylenediamine. Komabe, kutentha kwa ammonolysis reaction kuyenera kukhala 160 mpaka 250°C, ndipo kuthamanga kuyenera kukhala pamwamba pa 4.0MPa. Sungunulani chinthu cha polyamine chosaphika pansi pa kuthamanga kochepa, sonkhanitsani magawo pa 160-210°C pansi pa kuthamanga kwa 1.3kPa, ndikupeza chinthu chomalizidwa. Chemicalbook of tetraethylpentamine mutazizira. Njira yoyeretsera: Sungunulani madzi ndi sodium yachitsulo kapena anhydrous calcium sulfate kenako gawanizani pansi pa kuthamanga kochepa. Muthanso kusungunula 150g ya tetraethylenepentamine mu 300mL ya 95% ethanol, ndikuchepetsa pang'onopang'ono 180mL ya hydrochloric acid yokhazikika pamene ikuzizira, kusunga kutentha pansi pa 20°C. Sefani choyeracho, chiyikeninso katatu ndi chisakanizo cha ethanol ndi madzi, sambitsani ndi ether, ndipo chiume pansi pa vacuum kuti mupeze tetraethylenepentamine hydrochloride yoyera.
