Ko te Tetraethylenepentamine, e mohiotia ana ko tritetraethylenediamine, whakapotohia ko TEPA, he wai kowhai, karaka-whero ranei. He ngawari te wairewa ki te wai, te waiwaro me te nuinga o nga whakarewa pararopi, kare e rewa i roto i te benzene me te etera.Ka ngawari te tango i te wai me te hauhā i te hau. Kawakawa. Ka whiwhihia ma te waiariki amination me te tauhohenga ammonolysis i waenga i te dichloroethane me te haukini, te whakakore me te kawakore katahi ka whakamakuku i raro i te pehanga iti. Ka whakamahia hei otinga chromatography hau mo te pupuri whiriwhiri me te wehenga pukapuka matū o nga waipiro, amine, pyridine, quinoline, piperazine, thiols me te wai. Ka whakamahia i roto i nga kapia whakawhiti anion, nga taapiri hinu whakahinuhinu, nga taapiri hinu hinu hinu, ka whakamahia ano hoki hei kaihoko rongoa epoxy resin, he kaiwhakatere rapa vulcanization, etc.

Te kaupapa

:Ka taea te whakamahi Tetraethylene pentamine mo te titration matatini o te parahi, te konutea me te nickel na roto i te tikanga mutunga o naianei, te saponification o nga matū waikawa, te rapa waihanga me te kapia hau purenga me te kaihoko matewai. Ka whakamahia ano hei taapiri, hei rongoa rongoa, whakatere, aha atu.

Tikanga whakaputa:

Ko tenei hua he hua-tahi o te ethylenediamine, diethylenetriamine, triethylenetetramine, me te polyethylenepolyamine. Mo nga tikanga whakangao me nga mahi, tirohia koa te ethylenediamine. Engari, me 160 ki te 250°C te pāmahana o te tauhohenga ammonolysis, me te pehanga ki runga ake i te 4.0MPa. Kohia te hua polyamine masivesivá i raro i te pehanga iti, kohia nga hautau ki te 160-210°C i raro i te pehanga 1.3kPa, ka whiwhi i te pukapuka matū o te tetraethylpentamine i muri i te whakamahana. Tikanga whakamahine: Whakakorehia ki te konutai konukawata me te konupora konupūmā pākawa ngāwhā, ka hautauhia i raro i te pēhanga iti. Ka taea hoki e koe te whakakore i te 150g o te tetraethylenepentamine i roto i te 300mL o te 95% ethanol, me te whakaheke haere ki roto i te 180mL o te waikawa puota wai i te wa e whakamahana ana, me te pupuri i te pāmahana i raro iho i te 20°C. Tātarihia te rerenga ma, whakamaua kia toru nga wa ki te ranunga o te waihano me te wai, horoi ki te etera, ka whakamaroke i raro i te korehau kia whiwhi te tetraethylenepentamine hydrochloride parakore.
