Okwu mmalite

M-nitroaniline bụ ngwakọta organic. Ọ bụ kristal na-acha odo odo nwere isi adịghị mma pụrụ iche.

 

Isi ojiji nke m-nitroaniline bụ dị ka agba agba agba na dị ka akụrụngwa maka mgbawa. Ọ nwere ike ịkwadebe ogige ndị ọzọ site n'imeghachi omume na ụfọdụ ogige, dị ka ogige nitrate nwere ike ịkwadebe site na mmeghachi omume na nitric acid, ma ọ bụ dinitrobenzoxazole nwere ike ịkwadebe site na-emeghachi omume na thionyl chloride.

 

Enwere ike nweta usoro nkwadebe nke m-nitroaniline site na mmeghachi omume nke m-aminophenol na nitric acid. Nzọụkwụ a kapịrị ọnụ bụ igbari m-aminophenol na sulfuric acid nwere nitric acid wee kpalite mmeghachi omume ahụ, wee dị jụụ na crystallize ka emesịa nweta ngwaahịa nke m-nitroaniline.

 

Ozi nchekwa: M-nitroaniline bụ ihe na-egbu egbu nke nwere mmetụta na-akpasu iwe na anya, akpụkpọ ahụ, na akụkụ iku ume. Mmekọrịta na akpụkpọ ahụ nwere ike ịkpata mbufụt na ọbara ọbara, na iku ume nke nnukwu uzuzu ma ọ bụ uzuzu nwere ike ịkpata nsị. Yiri ugogbe anya nchebe, uwe aka, uwe nchebe, na respirators mgbe ị na-arụ ọrụ, ma hụ na a na-arụ ọrụ ahụ na ọnọdụ ikuku dị mma. Ekwesịrị iji mmiri buru ibu sachaa kọntaktị ọ bụla ozugbo wee gwọọ ya ozugbo na nlekọta ahụike. Ọzọkwa, m-nitroaniline bụ ihe mgbawa na ekwesịrị ka echekwa ya ka ọ ghara imeghe ọkụ na oke okpomọkụ.
