I-Diethylenetriamine CAS: 111-40-0

imvelo
Uketshezi olukhanyayo lwe-hygroscopic olukhanyayo olunephunga elimnandi le-ammonia, oluvutha umlilo futhi lune-alkaline enamandla. Incibilika emanzini, i-acetone, i-benzene, i-ether, i-methanol, njll., ayincibiliki ku-n-heptane, futhi igqwalisa ithusi nama-alloys ayo. Iphuzu lokuncibilika -35 ℃. Iphoyinti lokubilisa 207℃. Ukuminyana okuhlobene o. 9586. Iphoyinti elikhanyayo 94℃. Inkomba ye-Refractive 1. 4810. Lo mkhiqizo unokusebenza kabusha kwama-amine esibili futhi usabela kalula ngezinhlanganisela ezihlukahlukene. Okuphuma kuyo kunezinhlobonhlobo zokusetshenziswa.

Indlela yokulungiselela
Ingatholakala nge-ammoniation ye-dichloroethane. I-1,2-Ethyl chloride namanzi e-ammonia athunyelwa ku-reactor ye-tubular ukuze enze ukusabela kwe-ammoniation yokucindezela okushisa ku-150-250 ° C kanye nengcindezi engu-392.3kPa. Isixazululo sokusabela sincishiswa nge-alkali ukuze kutholwe ama-amine amahhala axutshwe, agxilwe ngenkathi esusa i-sodium chloride. Umkhiqizo ongahluziwe ube usukhishwa ngaphansi kwengcindezi encishisiwe futhi ingxenyenamba ephakathi kuka-195 no-215°C iyanqanyulwa ukuze kutholwe umkhiqizo osuphelile. Le ndlela ikhiqiza i-ethylenediamine, i-triethylenetetramine, i-tetraethylenepentamine ne-polyethylenepolyamine ngesikhathi esifanayo. Ingatholakala ngokulawula izinga lokushisa lombhoshongo wokucwiliswa kwamanzi ukuze kugaywe ingxube ye-amine nokunqamula izingxenyana ezihlukene ukuze kuhlukaniswe.

sebenzisa
Lo mkhiqizo usetshenziswa kakhulu njenge-solvent kanye ne-organic synthesis intermediate, futhi ungasetshenziswa ukulungisa ama-epoxy resin curing agents, izihlanzi zegesi (zokukhipha i-CO2), izithasiselo zikawoyela wokugcoba, ama-emulsifiers, amakhemikhali ezithombe, ama-surfactants, nama-ejenti aqeda indwangu. , isithuthukisi sephepha, i-aminocarboxylic complexing agent, i-metal chelating agent, i-heavy metal hydrometallurgy kanye ne-ejenti yokusabalalisa i-cyanide-free electroplating, i-brightener, ne-synthetic ion exchange resin ne-polyamide resin, njll.
