Ko te Tetraethylenepentamine, e mōhiotia ana ko te tritetraethylenediamine, e whakarāpopototia ana ko TEPA, he wai matotoru kōwhai, karaka-whero rānei. He ngāwari te wairewa ki te wai, te etanoru me te nuinga o ngā whakarewa waro, kāore e wairewa ki te benzene me te ether. Ka ngāwari te mimiti i te wai me te hauhā waro i te rangi. He kawakore. Ka whiwhihia mā te whakamahana wera me te tauhohenga ammonolysis i waenga i te dichloroethane me te haukini, ka whakakorengia ki te kawakore, kātahi ka whakatōtō i raro i te pēhanga iti. Ka whakamahia hei otinga tūmau chromatography hau mō te pupuri whiriwhiri me te wehenga matū o ngā waipiro, amines, pyridine, quinoline, piperazine, thiols me te wai. Ka whakamahia i roto i ngā kapia whakawhiti anion, ngā tāpiringa hinu whakahinuhinu, ngā tāpiringa hinu wahie, ā, ka whakamahia hoki hei kaihoko whakaora kapia epoxy, hei whakateretere whakamomona rapa, me ētahi atu.

Kaupapa

Ka taea te whakamahi i te Tetraethylene pentamine mō te titration matatini o te parahi, te konutea me te nikara mā te tikanga mutunga o nāianei, te saponification o ngā matū waikawa, te purenga hau rapa hangai me te kapia me te kaihoko whakamaroke. Ka whakamahia hoki hei tāpiri, hei kaihoko whakaora, hei whakateretere, me ētahi atu.

Tikanga whakaputa:

He hua tahi tēnei o te ethylenediamine, te diethylenetriamine, te triethylenetetramine, me te polyethylenepolyamine. Mō ngā mātāpono whakaputa me ngā mahi, tirohia te ethylenediamine. Heoi, me 160 ki te 250°C te pāmahana o te tauhohenga ammonolysis, ā, me neke ake te pēhanga i te 4.0MPa. Whakarewahia te hua polyamine mata i raro i te pēhanga iti, kohia ngā wāhanga i te 160-210°C i raro i te pēhanga o te 1.3kPa, ā, whiwhi i te hua oti o te tetraethylpentamine i muri i te whakamatao. Tikanga whakamahine: Whakamarokehia ki te konutai whakarewa, ki te konupūmā whanariki anhydrous rānei, kātahi ka wehewehea i raro i te pēhanga iti. Ka taea hoki e koe te whakarewa i te 150g o te tetraethylenepentamine ki roto i te 300mL o te 95% etanoru, ā, ka maturuturu mārire ki roto i te 180mL o te waikawa hauwai kukū i te wā e whakamatao ana, me te pupuri i te pāmahana i raro i te 20°C. Tātarihia te matū mā, whakakōhatuhia kia toru ngā wā ki te ranunga o te etanoru me te wai, horoia ki te etera, ka whakamaroke i raro i te korehau kia puta ai he tetraethylenepentamine hydrochloride parakore.
