Tetraethylenepentamine, oo sidoo kale loo yaqaan tritetraethylenediamine, oo loo soo gaabiyo TEPA, waa dareere huruud ah ama casaan-liin ah. Si fudud ugu milmi kara biyaha, ethanol iyo inta badan dareerayaasha dabiiciga ah, oo aan ku milmi karin benzene iyo ether. Si fudud ayay u nuugtaa biyaha iyo kaarboon laba ogsaydh hawada. Alkaline. Waxaa laga helaa falcelinta kulaylka iyo falcelinta ammonolysis ee u dhaxaysa dichloroethane iyo ammonia, iyadoo dhexdhexaadinaysa alkali ka dibna lagu milmayo cadaadis yar. Waxaa loo isticmaalaa sidii xal gaas ah oo loogu talagalay haynta xulashada iyo kala soocida aalkolada, amiinada, pyridine, quinoline, piperazine, thiols iyo biyaha. Waxaa loo isticmaalaa resins-ka is-weydaarsiga anion, walxaha saliidda lagu daro ee saliidda lagu daro, waxyaabaha saliidda shidaalka lagu daro, iyo sidoo kale loo isticmaalo sida wakiilada daaweynta resin epoxy, dardar-geliyaha caagga ah ee vulcanization, iwm.

Ujeeddo

:Tetraethylene pentamine waxaa loo isticmaali karaa titration adag oo naxaas, zinc iyo nikkel ah iyadoo la adeegsanayo habka ugu dambeeya ee hadda jira, saponification ee walxaha aashitada leh, nadiifinta gaaska caagga iyo resin-ka ee synthetic-ga ah iyo wakiilka fuuq-baxa. Waxaa sidoo kale loo isticmaalaa sidii lagu daro, wakiilo daaweyn, dardar-geliyeyaal, iwm.

Habka wax soo saarka:

Badeecadani waa wax soo saar ay wadaagaan ethylenediamine, diethylenetriamine, triethylenetetramine, iyo polyethylenepolyamine. Mabaadi'da wax soo saarka iyo hawlgallada, fadlan tixraac ethylenediamine. Si kastaba ha ahaatee, heerkulka falcelinta ammonolysis waxay u baahan tahay inay noqoto 160 ilaa 250°C, cadaadiskuna waa inuu ka sarreeyaa 4.0MPa. Badeecada polyamine ee cayriin ku milmi cadaadis la dhimay, ururi jajabyada 160-210°C cadaadis 1.3kPa ah, oo hel badeecada la dhammeeyay ee tetraethylpentamine ka dib qaboojinta. Habka sifeynta: Fuuq-baxa ku daadi sodium bir ah ama calcium sulfate aan biyo lahayn ka dibna kala qaybi cadaadis la dhimay. Waxa kale oo aad ku milmi kartaa 150g oo tetraethylenepentamine ah 300mL oo ah 95% ethanol, oo si tartiib tartiib ah ugu dhaadhac 180mL oo ah aashitada hydrochloric ee xooggan inta aad qaboojinayso, adigoo heerkulka ka dhigaya mid ka hooseeya 20°C. Shaandhee qulqulka cad, saddex jeer dib u warshadee isku darka ethanol iyo biyo, ku dhaq ether, oo ku qalaji faakiyuum si aad u hesho tetraethylenepentamine hydrochloride saafi ah.
