Taw qhia
Azodicarboxamide (N, N'-dimethyl-N, N'-dinitrosoglylamide) yog cov xim tsis muaj kob crystalline nrog cov khoom tshwj xeeb thiab ntau yam kev siv.
Zoo:
Azodicarboxamide yog cov xim tsis muaj xim nyob rau hauv chav tsev kub, soluble nyob rau hauv acids, alkalis thiab organic solvents, thiab muaj solubility zoo.
Nws yog raug rau cua sov los yog tshuab thiab tawg, thiab yog cais raws li explosive.
Azodicarboxamide muaj zog oxidizing zog thiab tuaj yeem hnov mob hnyav nrog combustibles thiab yooj yim oxidized tshuaj.
Siv:
Azodicarboxamide yog dav siv nyob rau hauv lub teb ntawm tshuaj synthesis thiab yog ib qho tseem ceeb reagent thiab intermediate nyob rau hauv ntau organic synthesis tshuaj.
Nws yog siv los ua raw khoom rau dye pigments hauv kev lag luam dye.
Txoj kev:
Txoj kev npaj ntawm azodicarbonamide feem ntau yog raws li hauv qab no:
Nws yog tsim los ntawm cov tshuaj tiv thaiv ntawm nitrous acid thiab dimethylurea.
Nws yog tsim los ntawm cov tshuaj tiv thaiv ntawm soluble dimethylurea thiab dimethylurea pib los ntawm nitric acid.
Cov ntaub ntawv kev nyab xeeb:
Azodicarboxamide yog qhov tawg heev thiab yuav tsum khaws cia kom deb ntawm qhov hluav taws kub, kev sib txhuam, cua sov thiab lwm yam khoom siv hluav taws xob.
Cov hnab looj tes tiv thaiv tsim nyog, tsom iav, thiab qhov ncauj qhov ntswg yuav tsum hnav thaum siv azodicarbonamide.
Tsis txhob sib cuag nrog oxidants thiab combustibles thaum ua haujlwm.
Azodicarbonamide yuav tsum muab khaws cia rau hauv qhov chaw kaw, txias, qhov cua zoo kom deb ntawm tshav ntuj ncaj qha.
