Ko te Tetraethylenepentamine, e kiia ana ko te tritetraethylenediamine, ko te TEPA rānei, he wai tirikara kōwhai, karaka-whero rānei, he maha ngā āhuatanga. He ngāwari te wairewa ki te wai, ki te waipiro ethyl, me te nuinga o ngā whakarewa waro, engari kāore e wairewa ki te benzene me te quintessence. Ka taea e tēnei matū te mimiti i te wai me te hauhā waro mai i te rangi, ka hangaia he āhua kawakore. He mea whakamahi noa te TEPA i roto i ngā tono maha pēnei i te otinga tūmau chromatography hau mō te pupuri me te wehewehe i ngā matū rerekē pēnei i te waipiro, amine, pyridine, quinoline, piperazine, thiols, me te wai. Ka whakamahia hoki i roto i te kapia whakawhiti anion, te tāpiri hinu whakahinuhinu, te tāpiri hinu wahie, ā, hei kaihoko whakapakeke kapia epoxy me ngā whakaterenga whakamomona rapa.

Kaupapa:I kitea te whakamahinga o te Tetraethylenepentamine i roto i te titration matatini o ngā huānga konganuku pēnei i te parahi, te konutea, me te nikara, mā te whakamahi i te tikanga mutunga o nāianei. E whakamahia ana hoki i roto i te saponification o ngā matū waikawa, te purenga hau, te kaihoko whakamaroke, te rapa hangai, me te tono kapia. Hei tāpiri, e whakamahia ana te TEPA hei tāpiri, hei kaihoko whakapakeke, me te whakateretere i roto i ngā ahumahi maha.

Ko te hanga o te tetraethylenepentamine he maha ngā arawhata, ā, he taonga waro monoxide o te ethylenediamine, te diethylenetriamine, te triethylenetetramine, me te polyethylenepolyamine. Ko te tikanga hanga ko te whakamahana wera me te tauhohenga matū ammonolysis, te whakakorenga, me te whakatōtō i raro i te pēhanga whakaiti. Ko te tukanga whakamahine ko te whakamaroke, te wehewehenga i raro i te pēhanga whakaiti, me te hanga anō kia whiwhi ai i te tetraethylenepentamine hydrochloride parakore. Me te taumaha ngota o te 189.3 me te nama konupūmā 112-57-2, ko te koki hāora TEPA he kohua o te 340° nekehanga centigrade, he mātotoru o te 0.998g/miliritara i te 25° nekehanga centigrade, me te pūmahana mura o te 365°F.

te māramatangangā purongo pakihiHe mea nui te mōhio ki ngā āhuatanga o te mākete, te taupū ōhanga, me ngā whakahoutanga o te kamupene, ka taea e te tangata te whakatau pai mō te haumi, te mahi tahi, me te kaupapa pakihi. Mā te tātari i ngā raraunga, te matapae i ngā nekehanga o te mākete, me te mārama ki te pānga o ngā huihuinga o te ao ki te pakihi ka āwhina i te tangata ki te whakatere i te whenua mana o te ao pakihi. Kia mau tonu ki ngā whanaketanga hou o ngā purongo pakihi kia noho whakamua ai i roto i te taiao mākete whakataetae.
