I-Diethylenetriamine CAS 111-40-0

Iwuketshezi olunamafutha angenambala noma oluphuzi ngokukhanyayo olunephunga le-ammonia nokucasuka. Ukuminyana okuhlobene nokuvutha ngu-0.9542 (20℃), indawo yokuncibilika ngu--39℃, iphoyinti elibilayo ngu-207℃, futhi indawo ekhanyayo ingu-94℃. Incibilika emanzini, i-ethanol ne-acetone, ayincibiliki ku-ether. Ine-alkaline kakhulu futhi ihlangana ne-asidi ukwenza usawoti ohambisanayo. Yakha kalula izinkimbinkimbi ezinosawoti wensimbi esindayo. I-hygroscopic kakhulu futhi imunca kalula umswakama kanye ne-carbon dioxide emoyeni, yakhe intuthu emhlophe emoyeni. Igqwala kakhulu futhi iyagqwala kuma-alloys ethusi nawethusi. Igqwala kakhulu futhi iyacasula isikhumba, ulwelwesi lwamafinyila kanye nomgudu wokuphefumula.

[Sebenzisa]

Isetshenziswa njenge-organic synthesis intermediates kanye nezinyibilikisi. Isetshenziswa ekwenzeni ama-polyamide resins, ama-ion exchange resins, ama-surfactants, izithasiselo zokugcoba, ama-ejenti aqeda indwangu namakhemikhali ezithombe. Ibuye isetshenziswe ngokujwayelekile njenge-ejenti yokwelapha izinga lokushisa legumbi le-epoxy resin, isihlanzi segesi, i-ejenti yokuqinisa amaphepha, i-aminocarboxylic complexing agent, i-metal chelating agent, i-brightener, njll.

[Indlela yokulungiselela emfushane] Ilungiswa ngokwenza i-hot-pressure amination kanye ne-ammonolysis reactions phakathi kwe-dichloroethane ne-ammonia ku-100~150℃ kanye ne-4MPa, ingathathi hlangothi nge-alkali bese i-distilling. Ifomula yokusabela imi kanje:

[Ukuphepha Nokuvikela]

Ipakishwe emiphongolweni yepulasitiki ye-polyethylene enesisindo esinesisindo esingu-50kg emgqonyeni ngamunye; ingabuye ifakwe emiphongolweni yensimbi enesisindo esingama-200kg emgqonyeni ngamunye; ngamanani amancane, ingapakishwa kumabhodlela engilazi angu-0.5kg noma angu-1kg. Gcina endaweni epholile futhi enomoya, futhi ungahlali ndawonye futhi uthuthe ngama-acids.

Lo mkhiqizo uwuketshezi oludlayo olune-alkali. Uma isikhumba sithintana, sigeze ngokushesha ngamanzi noma nciphisa isisombululo se-boric acid.
