Okwu mmalite
Diphenylamine bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke diphenylamine:
Ogo:
Ọdịdị: Diphenylamine bụ kristal ọcha siri ike na isi amine na-adịghị ike.
Solubility: Ọ na-agbaze na ihe mgbaze organic dị ka ethanol, benzene na methylene chloride n'ime ụlọ okpomọkụ, mana ọ naghị esiri ya ike na mmiri.
Nkwụsi ike: Diphenylamine kwụsiri ike n'okpuru ọnọdụ nkịtị, ọ ga-abụ oxidize na ikuku, ma nwee ike imepụta gas na-egbu egbu.
Jiri:
Dye na pigmenti ụlọ ọrụ: Diphenylamine na-eji ọtụtụ ebe na njikọ nke e ji esiji ákwà na pigmenti, nke nwere ike iji agba eriri, akpụkpọ anụ na plastics, wdg.
Nnyocha kemịkalụ: Diphenylamine bụ ihe dị mkpa na-arụ ọrụ na njikọ organic ma a na-ejikarị emepụta carbon-carbon na carbon-nitrogen bond.
Usoro:
Usoro nkwadebe nke diphenylamine na-enweta site na mmeghachi omume amino dehydrogenation nke aniline. A na-ejikarị ihe ndị na-emepụta gas-phase catalysts ma ọ bụ palladium catalysts eme ihe iji kwado mmeghachi omume ahụ.
Ozi nchekwa:
Ikuku ume, imi, ma ọ bụ kọntaktị na akpụkpọ ahụ nwere ike ịkpasu iwe ma na-emebi anya.
N'oge a na-eji ma na-ebu, a ga-ezere kọntaktị na akpụkpọ ahụ na anya, na ọnọdụ ikuku kwesịrị ekwesị kwesịrị iburu n'uche.
Diphenylamine bụ ọrịa carcinogen nwere ike ịdị na ya, a ga-agbasokwa usoro ọrụ nchekwa dị mkpa yana ịgbaso ụkpụrụ. Ekwesịrị iyi akụrụngwa nchebe kwesịrị ekwesị mgbe ejiri ya wee rụọ ya n'ụlọ nyocha.
Ihe dị n'elu bụ okwu mmeghe nke ihe onwunwe, ojiji, ụzọ nkwadebe na ozi nchekwa nke diphenylamine. Maka ozi ndị ọzọ, biko kpọtụrụ akwụkwọ ndị dị mkpa ma ọ bụ kpọtụrụ ọkachamara.
