I-Diethylenetriamine CAS 111-40-0

Lulwelo olunamafutha angenambala okanye olukhanyayo olutyheli olucacileyo olunevumba le-ammonia kunye nokucaphuka. Ukuxinana kokutsha yi-0.9542 (20℃), indawo yokunyibilika ngu-39℃, indawo yokubilisa yi-207℃, kunye ne-flash point yi-94℃. Inyibilika emanzini, i-ethanol kunye ne-acetone, ayinyibiliki kwi-ether. Inealkaline kakhulu kwaye idibana neasidi ukwenza iityuwa ezihambelanayo. Yenza ngokulula ii-complex kunye neetyuwa zetsimbi enzima. I-hygroscopic kakhulu kwaye ifunxa ngokulula ukufuma kunye nekharbon diokside emoyeni, yenze umsi omhlophe emoyeni. Inomhlwa kakhulu kwaye iyatshisa kwialloyi zobhedu kunye nezobhedu. I-corrosion kakhulu kwaye iyacaphukisa ulusu, i-mucous membranes kunye ne-respiratory tract.

[Sebenzisa]

Isetyenziswa njenge-organic synthesis intermediates kunye nezinyibilikisi. Isetyenziswa ekwenzeni i-polyamide resins, i-ion exchange resins, i-surfactants, izongezo ze-lubricant, ii-agent zokugqiba ilaphu kunye neekhemikhali zefoto. Ikwasetyenziswa ngokuqhelekileyo njengearhente yokunyanga ubushushu begumbi kwi-epoxy resin, isicoci segesi, iarhente yokuqinisa iphepha, i-aminocarboxylic i-agent complexing agent, i-metal chelating agent, brightener, njl.

[Indlela yokulungiselela emfutshane] Ilungiswa ngokwenza i-amination yoxinzelelo olushushu kunye ne-ammonolysis reactions phakathi kwe-dichloroethane kunye ne-ammonia kwi-100 ~ 150℃ kunye ne-4MPa, i-neutraizing nge-alkali kwaye emva koko i-distilling. Ifomula yokusabela imi ngolu hlobo lulandelayo:

[Ukhuseleko kunye noKhuselo]

Ipakishwe kwimibhobho yeplastiki ye-polyethylene kunye nobunzima obungama-50kg emphanda; isenokupakishwa kwimiphanda yentsimbi enobunzima obungama-200kg emphanda; ngobungakanani obuncinci, inokupakishwa kwi-0.5kg okanye i-1kg yeebhotile zeglasi. Gcina kwindawo epholileyo kunye nomoya, kwaye ungahlali kunye nokuthutha nge-acids.

Le mveliso lulwelo olune-alkaline elonakalisayo. Ukuba ulusu ludibana, luhlambe ngokukhawuleza ngamanzi okanye uhlambulule isisombululo se-boric acid.
