Okwu mmalite
Benzidine (nke a makwaara dị ka diphenylamine) bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke ọdịdị ya, ojiji ya, ụzọ mmepụta ya na ozi nchekwa:
Ogo:
- Ọdịdị: Benzidine bụ ọcha na-acha odo odo kristal siri ike.
- Solubility: ihe na-adịghị ike na mmiri, soluble na organic solvents dị ka alcohols, ethers, wdg.
- Akara: Ọ bụ electrophile nwere njirimara nke mmeghachi omume ngbanwe electrophilic.
Jiri:
- A na-eji Benzidine eme ihe n'ọtụtụ ebe n'ọhịa nke njikọ organic. Enwere ike iji ya dị ka ihe eji eme ihe na etiti sịntetik maka kemịkalụ dị ka ịjiji, pigmenti, plastik, wdg.
Usoro:
- A na-akwado Benzidine site na mbelata dinitrobiphenyl, mkpochapụ radieshon nke haloaniline, wdg.
- Ụzọ nkwadebe nke oge a gụnyere njikọ organic nke amines aromatic, dị ka mmeghachi omume nke mkpụrụ diphenyl ether na amino alkanes.
Ozi nchekwa:
- Benzidine na-egbu egbu ma nwee ike ịkpasu iwe na imebi ahụ mmadụ.
- Mgbe a na-eji benzidine eme ihe, ekwesịrị ịkpachara anya ka ọ ghara imetụ akpụkpọ ahụ na ikuku ume, na a ga-eyi ihe nchekwa dịka uwe aka, ugogbe anya nchebe na ihe mkpuchi ma ọ bụrụ na ọ dị mkpa.
- Mgbe benzidine batara na akpụkpọ ahụ ma ọ bụ anya, ekwesịrị iji mmiri buru ibu sachaa ya ozugbo.
- Mgbe ị na-echekwa ma na-eji benzidine, lezie anya ka ị zere kọntaktị na ihe ndị dị ndụ na oxidants iji gbochie ọkụ ma ọ bụ mgbawa.
