Diethylenetriamine CAS 111-40-0

Iyo isina ruvara kana yakareruka yero inoonekera yemafuta ine mafuta ane ammonia kunhuhwirira uye kutsamwa. Hukama hwekupisa density i0.9542 (20 ℃), panonyungudika i -39 ℃, panovira i207 ℃, uye flash point i94 ℃. Soluble mumvura, ethanol uye acetone, isinganyunguriki mu ether. Iyo ine alkaline yakawanda uye inopindirana neasidhi kuita munyu unoenderana. Gadzira zviri nyore macomplexes ane heavy metal salts. Iyo yakanyanya hygroscopic uye inotora nyore hunyoro uye carbon dioxide mumhepo, ichigadzira chiutsi chichena mumhepo. Inoita ngura zvakanyanya uye inokanganisa masimbi emhangura nemhangura. Yakanyanya corrosive uye inogumbura ganda, mucous membranes uye kufema turakiti.

[Shandisa]

Inoshandiswa se organic synthesis intermediates uye solvents. Inoshandiswa mukugadzira polyamide resins, ion exchange resins, surfactants, lubricant additives, machira ekupedzisa maajenti uye makemikari emifananidzo. Iyo inowanzo shandiswa seyekamuri tembiricha yekurapa mumiriri we epoxy resin, gasi rekuchenesa, bepa rinosimbisa mumiriri, aminocarboxylic complexing agent, metal chelating agent, brightener, nezvimwe.

[Nzira yekugadzirira pfupi] Inogadzirwa nekuita kupisa-kudzvanywa amination uye ammonolysis reactions pakati pedichloroethane neammonia pa100 ~ 150 ℃ uye 4MPa, neutralizing nealkali uyezve distilling. Iyo reaction formula ndeyotevera:

[Kuchengetedzwa uye Dziviriro]

Iyo yakarongedzwa mumadhiramu epurasitiki epolyethylene ane huremu hwemambure e50kg padhiramu; inogona zvakare kurongedzerwa mumadhiramu esimbi ane huremu hwemambure e200kg padhiramu; muhuwandu hudiki, inogona kurongedzerwa mu 0.5kg kana 1kg mabhodhoro egirazi. Chengetedza munzvimbo inotonhorera uye inofefetera, uye usagarisane uye kutakura nemaasidhi.

Ichi chigadzirwa imvura ine alkaline corrosive liquid. Kana ganda rikasangana, rigeze pakarepo nemvura kana dilute boric acid solution.
