I-Diethylenetriamine CAS 111-40-0

Lulwelo olunamafutha olungenambala okanye olutyheli olukhanyayo, olunombala otyheli kwaye lubonakala luvutha. Ubuninzi bokutsha buyi-0.9542 (20℃), iqondo lokunyibilika liyi-39℃, iqondo lokubila liyi-207℃, kwaye iqondo lokukhanya liyi-94℃. Lunyibilika emanzini, kwi-ethanol nakwi-acetone, alunyibiliki kwi-ether. Lune-alkaline eninzi kwaye luphendula ne-asidi ukwenza iityuwa ezifanayo. Luyakha ngokulula ii-complexes ngeetyuwa zesinyithi esinzima. Lune-hygroscopic kakhulu kwaye lufunxa lula umswakama kunye ne-carbon dioxide emoyeni, lwenze umsi omhlophe emoyeni. Lunobuthi kakhulu kwaye lunobuthi kwi-alloys zekopolo kunye ne-copper. Lunobuthi kakhulu kwaye lucaphukisa ulusu, ii-membrane ze-mucous kunye neendlela zokuphefumla.

[Sebenzisa]

Isetyenziswa njengezinto ezidityanisiweyo kunye nezinyibilikisi ze-organic synthesis. Isetyenziswa ekwenziweni kwee-polyamide resins, ii-ion exchange resins, ii-surfactants, izongezo ze-lubricant, ii-lap finishing agents kunye neekhemikhali zefoto. Ikwasetyenziswa njenge-ejenti yokupholisa ubushushu begumbi kwi-epoxy resin, i-gas purifier, i-paper reinforcement agent, i-aminocarboxylic complexing agent, i-metal chelating agent, i-brightener, njl.njl.

[Indlela emfutshane yokulungiselela] Ilungiswa ngokwenza i-hot-pressure amination kunye ne-ammonolysis reactions phakathi kwe-dichloroethane kunye ne-ammonia kwi-100 ~ 150℃ kunye ne-4MPa, inyibilikisa nge-alkali ize emva koko ihluzwe. Ifomula yempendulo yile ilandelayo:

[Ukhuseleko kunye noKhuseleko]

Ipakishwe kwiibhareli zeplastiki zepolyethylene ezinobunzima obupheleleyo obuyi-50kg ngebhareli; ingapakishwa nakwiibhareli zesinyithi ezinobunzima obupheleleyo obuyi-200kg ngebhareli; ngobuninzi obuncinci, ingapakishwa kwiibhotile zeglasi eziyi-0.5kg okanye i-1kg. Gcina kwindawo epholileyo nengena umoya, kwaye ungahlali kunye kwaye uthuthe nee-asidi.

Le mveliso lulwelo olune-alkaline enamandla. Ukuba ulusu ludibana, luhlambe ngoko nangoko ngamanzi okanye udibanise isisombululo se-boric acid.
