I-Diethylenetriamine CAS 111-40-0

Luketshezi olunamafutha olungenambala noma oluphuzi olukhanyayo olunombala okhanyayo olunephunga le-ammonia kanye nokucasuka. Ubuningi bokusha bungu-0.9542 (20℃), iphuzu lokuncibilika lingu-39℃, iphuzu lokubila lingu-207℃, kanti iphuzu lokusha lingu-94℃. Luncibilika emanzini, i-ethanol kanye ne-acetone, aluncibiliki ku-ether. Lune-alkaline kakhulu futhi luphendula ne-asidi ukuze lwakhe usawoti ohambisanayo. Lwakha kalula ama-complex ngosawoti wensimbi osindayo. Lune-hygroscopic kakhulu futhi lumunca kalula umswakama kanye ne-carbon dioxide emoyeni, lwakha intuthu emhlophe emoyeni. Lunobuthi kakhulu futhi lunobuthi kuma-alloy ethusi nawethusi. Lunobuthi kakhulu futhi lucasula isikhumba, ulwelwesi lwamafinyila kanye nendlela yokuphefumula.

[Sebenzisa]

Isetshenziswa njengezinto ezihlanganisa ukwenziwa kwezinto eziphilayo kanye nezinyibilikisi. Isetshenziswa ekwenziweni kwama-polyamide resins, ama-ion exchange resins, ama-surfactants, izithasiselo zokugcoba, izinto zokuqeda indwangu kanye namakhemikhali ezithombe. Isetshenziswa futhi njenge-ejenti yokwelapha izinga lokushisa legumbi le-epoxy resin, i-gas purifier, i-paper reinforcement agent, i-aminocarboxylic complexing agent, i-metal chelating agent, i-brightener, njll.

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

[Ukuphepha Nokuvikelwa]

Ipakishwe emiphongolweni yepulasitiki ye-polyethylene enesisindo esingama-50kg ngomgqomo; ingapakishwa futhi emiphongolweni yensimbi enesisindo esingama-200kg ngomgqomo; ngobuningi obuncane, ingapakishwa emabhodleleni engilazi angama-0.5kg noma angu-1kg. Gcina endaweni epholile futhi enomoya, futhi ungahlali ndawonye futhi uthuthe nama-asidi.

Lo mkhiqizo uketshezi olubolayo olune-alkaline kakhulu. Uma isikhumba sithintana, sigeze ngokushesha ngamanzi noma unciphise isixazululo se-boric acid.
