Diethylenetriamine CAS 111-40-0

Nws yog xim tsis muaj xim lossis lub teeb daj pob tshab oily kua nrog ammonia tsw thiab khaus khaus. Tus txheeb ze flammability ceev yog 0.9542 (20 ℃), lub melting point yog -39 ℃, boiling point yog 207 ℃, thiab flash point yog 94 ℃. Soluble hauv dej, ethanol thiab acetone, insoluble hauv ether. Nws yog alkaline heev thiab reacts nrog acid los tsim cov ntsev sib xws. Yooj yim tsim complexes nrog hnyav hlau ntsev. Nws yog hygroscopic heev thiab yooj yim absorbs ya raws thiab carbon dioxide nyob rau hauv cov huab cua, tsim cov pa luam yeeb dawb hauv huab cua. Nws yog corrosive heev thiab corrosive rau tooj liab thiab tooj liab alloys. Heev corrosive thiab irritating rau ntawm daim tawv nqaij, mucous daim nyias nyias thiab ua pa ib ntsuj av.

[Siv]

Siv ua organic synthesis intermediates thiab cov kuab tshuaj. Siv rau hauv kev tsim cov polyamide resins, ion pauv resins, surfactants, lubricant additives, ntaub xov xov thiab cov tshuaj yees duab. Nws kuj yog siv los ua chav tsev kub curing tus neeg saib xyuas rau epoxy resin, roj purifier, daim ntawv reinforcing tus neeg saib xyuas, aminocarboxylic complexing tus neeg saib xyuas, hlau chelating tus neeg saib xyuas, brightener, thiab lwm yam.

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

[Kev nyab xeeb thiab kev tiv thaiv]

Nws tau ntim rau hauv cov thawv yas polyethylene nrog qhov hnyav ntawm 50kg ib chim; nws tseem tuaj yeem ntim rau hauv cov thawv hlau nrog qhov hnyav ntawm 200kg ib chim; hauv me me, nws tuaj yeem ntim rau hauv 0.5kg lossis 1kg iav fwj. Khaws rau hauv qhov chaw txias thiab qhov cua, thiab tsis txhob sib xyaw thiab thauj nrog cov kua qaub.

Cov khoom no yog alkaline corrosive kua heev. Yog hais tias daim tawv nqaij los rau hauv kev sib cuag, ntxuav tam sim ntawd nrog dej los yog dilute boric acid tov.
