Tetraethylenepentamine, oo sidoo kale loo yaqaan tritetraethylenediamine, oo loo soo gaabiyo TEPA, waa dareere galgal ah oo huruud ah ama liimi-cas ah. Si fudud ugu milmay biyaha, ethanol iyo inta badan dareerayaasha organic, aan lagu milmin benzene iyo ether.Waxay si fudud u nuugtaa biyaha iyo carbon dioxide hawada. Alkaline. Waxaa lagu helaa kuleyl kuleyl ah iyo falcelinta ammonolysis ee u dhexeysa dichloroethane iyo ammonia, ka takhalusidda alkali ka dibna ka saar cadaadiska hoos u dhaca. Waxa loo istcimaalay xalal taagan oo chromatography gaas ah ee haynta doorashada iyo kala soocida buugta Kiimikada ee khamriga, amines, pyridine, quinoline, piperazine, thiols iyo biyaha. Loo isticmaalo xabagta sarrifka ah ee anion, saliid lagu daro saliidda, saliid lagu daro saliidda, iyo sidoo kale loo isticmaalo sida epoxy resin dawooyinka, dardar vulcanization caag, iwm.

Ujeedo

Pentamine Tetraethylene waxaa loo isticmaali karaa titration adag ee naxaasta, zinc iyo nikkel iyadoo la isticmaalayo habka dhamaadka hadda, saponification ee walxaha acidic, caag synthetic iyo sifaynta gaaska resin iyo wakiilka fuuqbaxa. Waxa kale oo loo isticmaalaa sida wax lagu daro, wakiilada daawaynta, dardargeliyayaasha, iwm.

Habka wax soo saarka:

Alaabtani waa wax-soo-saarka ethylenediamine, diethylenetriamine, triethylenetetramine, iyo polyetylenepolyamine. Mabaadi'da wax soo saarka iyo hawlgallada, fadlan tixraac ethylenediamine. Si kastaba ha ahaatee, heerkulka falcelinta ammonolysis wuxuu u baahan yahay inuu ahaado 160 ilaa 250 ° C, cadaadiskuna waa inuu ka sarreeyaa 4.0MPa. Ku kala saar badeecada polyamine-ka cayriin ee cadaadiska la dhimay, ku soo ururi jajabyada 160-210 ° C cadaadiska 1.3kPa, oo hel badeecada dhammaatay ee Kiimikada tetraethylpentamine qaboojinta ka dib. Habka sifaynta: Ku fuuqbax sodiyam macdan ah ama kaalshiyam sulfate anhydrous ah ka dibna kala jajabi cadaadiska hoos u dhaca. Waxa kale oo aad ku milmi kartaa 150g oo tetraethylenepentamine ah 300mL oo ah 95% ethanol, oo si tartiib tartiib ah u daadi 180mL oo ah acid hydrochloric acid inta aad qaboojinayso, adiga oo heerkulku ka hooseeyo 20°C. Sifey dabaylaha cad, ku celi saddex jeer isku dar ah ethanol iyo biyo, ku dhaq ether, oo ku qallaji faakuum hoostiisa si aad u hesho tetraethylenepentamine hydrochloride saafi ah.
