I-Diethylenetriamine CAS:111-40-0

imvelo
Uketshezi oluphuzi olucwebezelayo olunombala ocwebezelayo olunephunga elinamandla le-ammonia, oluvuthayo futhi olune-alkaline enamandla. Luncibilika emanzini, i-acetone, i-benzene, i-ether, i-methanol, njll., aluncibiliki ku-n-heptane, futhi luyabola kuthusi kanye ne-alloys yalo. Iphuzu lokuncibilika -35℃. Iphuzu lokubila 207℃. Ubuningi obuhlobene o. 9586. Iphuzu lokufiphaza 94℃. Inkomba yokufiphaza 1. 4810. Lo mkhiqizo une-reactivity yama-amine esibili futhi usabela kalula nezinhlobo ezahlukene zamakhemikhali. I-derivatives yawo inezinhlobo eziningi zokusetshenziswa.

Indlela yokulungiselela
Ingatholakala ngokufaka i-dichloroethane ku-ammonia. I-1,2-Ethyl chloride kanye namanzi e-ammonia kuthunyelwa ku-reactor eyishubhu ukuze yenze ukusabela kwe-ammonia okushisayo ekushiseni okungu-150-250°C kanye nokucindezela okungu-392.3kPa. Isixazululo sokusabela siyasuswa nge-alkali ukuze kutholakale ama-amine akhululekile axubile, agxilile ngenkathi kususwa i-sodium chloride. Umkhiqizo ongahluziwe ube usuhluzwa ngaphansi kokucindezela okuncishisiwe bese kuthi ingxenye ephakathi kuka-195 no-215°C ihluzwe ukuze kutholakale umkhiqizo oqediwe. Le ndlela ikhiqiza i-ethylenediamine, i-triethylenetetramine, i-tetraethylenepentamine kanye ne-polyethylenepolyamine ngesikhathi esifanayo. Ingatholakala ngokulawula izinga lokushisa lombhoshongo wokuhluza ukuze kuhluzwe ingxube ye-amine futhi kuhlungwe izingxenyana ezahlukene ukuze kuhlukaniswe.

sebenzisa
Lo mkhiqizo usetshenziswa kakhulu njenge-solvent kanye ne-organic synthesis intermediate, futhi ungasetshenziswa ukulungiselela ama-ejenti okwelapha i-epoxy resin, ama-gas purifier (okususa i-CO2), izithasiselo zamafutha okugcoba, ama-emulsifier, amakhemikhali ezithombe, ama-surfactants, kanye nama-ejenti okuqeda indwangu. , isithuthukisi sephepha, i-aminocarboxylic complexing agent, i-metal chelating agent, i-heavy metal hydrometallurgy kanye ne-cyanide-free electroplating diffusion agent, i-brightener, kanye ne-synthetic ion exchange resin kanye ne-polyamide resin, njll.
