Tetraethylenepentamine, yomwe imadziwikanso kuti tritetraethylenediamine, yofupikitsidwa ngati TEPA, ndi madzi achikasu kapena ofiira a viscous. Imasungunuka mosavuta m'madzi, ethanol ndi zosungunulira zambiri za organic, zosasungunuka mu benzene ndi ether. Imayamwa mosavuta madzi ndi carbon dioxide mumlengalenga. Zamchere. Imatengedwa ndi matenthedwe amination ndi ammonolysis reaction pakati pa dichloroethane ndi ammonia, neutralizing ndi alkali ndiyeno distilling pansi pa kupanikizika kochepa. Amagwiritsidwa ntchito ngati gasi chromatography stationary solution posungirako kusankha ndi Chemicalbook kulekanitsa ma alcohols, amines, pyridine, quinoline, piperazine, thiols ndi madzi. Amagwiritsidwa ntchito posinthanitsa ma resin a anion, zowonjezera mafuta opaka mafuta, zowonjezera zamafuta, komanso amagwiritsidwa ntchito ngati ma epoxy resin machiritso, ma accelerator a raba vulcanization, etc.

Cholinga

:Tetraethylene pentamine angagwiritsidwe ntchito kwa zovuta titration zamkuwa, nthaka ndi faifi tambala ndi njira panopa mapeto, saponification wa zinthu acidic, kupanga mphira ndi utomoni kuyeretsa mpweya ndi mpweya wothandizira. Amagwiritsidwanso ntchito ngati zowonjezera, machiritso othandizira, ma accelerator, etc.

Njira yopangira:

Izi ndizopangidwa ndi ethylenediamine, diethylenetriamine, triethylenetetramine, ndi polyethylenepolyamine. Kuti mumve mfundo zopangira ndi magwiridwe antchito, chonde onani ethylenediamine. Komabe, kutentha kwa ammonolysis reaction kuyenera kukhala 160 mpaka 250 ° C, ndipo kupanikizika kuyenera kukhala pamwamba pa 4.0MPa. Sakanizani mankhwala a polyamine osakanizidwa pang'onopang'ono, sonkhanitsani tizigawo ting'onoting'ono pa 160-210 ° C mokakamizidwa ndi 1.3kPa, ndipo pezani mankhwala omalizidwa Chemicalbook ya tetraethylpentamine mutazizirira. Njira yoyenga: Dehydrate ndi zitsulo za sodium kapena anhydrous calcium sulfate ndiyeno perekani pang'onopang'ono pansi pa kupanikizika. Mukhozanso kusungunula 150g ya tetraethylenepentamine mu 300mL ya 95% ethanol, ndipo pang'onopang'ono mutsike mu 180mL wa hydrochloric acid wokhazikika pamene mukuzizira, kusunga kutentha kosachepera 20 ° C. Sefa mpweya woyera, recrystallize katatu ndi chisakanizo cha Mowa ndi madzi, sambani ndi etha, ndi kuumitsa pansi pa vacuum kuti mupeze tetraethylenepentamine hydrochloride yoyera.
