Diethylenetriamine CAS 111-40-0

Nws yog ib yam roj tsis muaj xim los yog daj daj uas muaj ntxhiab ammonia thiab khaus khaus. Qhov ceev ntawm kev kub hnyiab yog 0.9542 (20 ℃), qhov melting point yog -39 ℃, qhov boiling point yog 207 ℃, thiab qhov flash point yog 94 ℃. Yaj hauv dej, ethanol thiab acetone, tsis yaj hauv ether. Nws yog alkaline heev thiab reacts nrog acid los tsim cov ntsev sib xws. Yooj yim tsim cov complexes nrog cov ntsev hlau hnyav. Nws yog hygroscopic heev thiab yooj yim nqus cov dej noo thiab carbon dioxide hauv huab cua, tsim cov pa dawb hauv huab cua. Nws yog corrosive heev thiab yog corrosive rau tooj liab thiab tooj liab alloys. Corrosive heev thiab khaus rau daim tawv nqaij, mucous membranes thiab txoj kev ua pa.

[Siv]

Siv ua cov tshuaj nruab nrab thiab cov kuab tshuaj organic synthesis. Siv rau hauv kev tsim cov polyamide resins, ion exchange resins, surfactants, cov roj nplua nyeem ntxiv, cov neeg ua tiav cov ntaub thiab cov tshuaj siv thaij duab. Nws kuj tseem siv tau ua tus neeg sawv cev kho qhov kub hauv chav rau epoxy resin, roj purifier, ntawv txhawb nqa tus neeg sawv cev, aminocarboxylic complexing agent, hlau chelating agent, brightener, thiab lwm yam.

[Txoj kev npaj luv luv] Nws yog npaj los ntawm kev ua cov tshuaj amination thiab ammonolysis kub ntawm dichloroethane thiab ammonia ntawm 100 ~ 150 ℃ thiab 4MPa, neutralizing nrog alkali thiab tom qab ntawd distillation. Cov mis tshuaj yog raws li nram no:

[Kev Nyab Xeeb thiab Kev Tiv Thaiv]

Nws tau ntim rau hauv cov thoob yas polyethylene nrog qhov hnyav tag nrho ntawm 50kg ib thoob; nws kuj tuaj yeem ntim rau hauv cov thoob hlau nrog qhov hnyav tag nrho ntawm 200kg ib thoob; hauv cov khoom me me, nws tuaj yeem ntim rau hauv lub raj mis iav 0.5kg lossis 1kg. Khaws cia rau qhov chaw txias thiab cua nkag, thiab tsis txhob nyob ua ke thiab thauj nrog cov kua qaub.

Cov khoom no yog cov kua alkaline corrosive heev. Yog tias daim tawv nqaij kov, ntxuav tam sim ntawd nrog dej lossis diluted boric acid kua.
