Taw qhia
Diphenylamine yog ib qho organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm diphenylamine:
Zoo:
Cov tsos mob: Diphenylamine yog dawb crystalline khoom nrog ib qho tsis muaj zog amine tsw.
Solubility: Nws yog soluble hauv cov kuab tshuaj organic xws li ethanol, benzene thiab methylene chloride ntawm chav tsev kub, tab sis insoluble hauv dej.
Kev ruaj ntseg: Diphenylamine kuj ruaj khov nyob rau hauv ib txwm muaj, yuav oxidize nyob rau hauv cov huab cua, thiab tej zaum yuav tsim cov pa phem.
Siv:
Dye thiab pigment kev lag luam: Diphenylamine yog dav siv nyob rau hauv lub synthesis ntawm dyes thiab pigments, uas yuav siv tau rau dye fibers, tawv thiab yas, thiab lwm yam.
Kev tshawb fawb tshuaj: Diphenylamine yog ib qho tseem ceeb reagent nyob rau hauv cov organic synthesis thiab feem ntau yog siv los tsim carbon-carbon thiab carbon-nitrogen bonds.
Txoj kev:
Txoj kev npaj ntau ntawm diphenylamine yog tau los ntawm cov amino dehydrogenation cov tshuaj tiv thaiv ntawm aniline. Gas-phase catalysts lossis palladium catalysts feem ntau yog siv los pab txhawb cov tshuaj tiv thaiv.
Cov ntaub ntawv kev nyab xeeb:
Kev nqus tau, noj, lossis kev sib cuag ntawm daim tawv nqaij tuaj yeem ua rau khaus thiab ua rau lub qhov muag corrosive.
Thaum siv thiab nqa, kev sib cuag ntawm daim tawv nqaij thiab lub qhov muag yuav tsum zam, thiab qhov cua kom zoo yuav tsum raug coj mus rau hauv tus account.
Diphenylamine yog qhov muaj peev xwm carcinogen thiab cov txheej txheem kev nyab xeeb ntawm kev ua haujlwm yuav tsum tau ua raws li cov cai nruj me ntsis. Cov cuab yeej tiv thaiv tsim nyog yuav tsum tau hnav thaum siv thiab ua haujlwm hauv chav kuaj.
Cov saum toj no yog cov lus qhia luv luv rau cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm diphenylamine. Yog xav paub ntxiv, thov nrog rau cov ntaub ntawv uas cuam tshuam los yog nrog tus kws tshaj lij.
