Koresha	Nitrobenzene ningirakamaro hagati yacyo. Nitrobenzene yashizwemo sulfure trioxide kugirango ibone aside m-nitrobenzene sulfonique. Irashobora gukoreshwa nk'irangi hagati, okiside yoroheje hamwe n'umunyu urwanya irangi. Nitrobenzene yashizwemo aside ya chlorosulfonike kugirango ibone chloride m-nitrobenzenesulfonyl, yakoreshwaga hagati y’irangi, imiti nibindi. Nitrobenzene ihindurwamo M-nitrochlorobenzene, ikoreshwa cyane mu gukora amarangi n'imiti yica udukoko. Nyuma yo kugabanuka, M-chloroaniline irashobora kuboneka. Ikoreshwa nk'irangi rya orange GC, ni na farumasi, imiti yica udukoko, imiti yera ya fluorescent, abahuza pigment organic. Nitrobenzene yongeye nitrasiyo irashobora kuba m-dinitrobenzene, mukugabanuka irashobora kuba m-phenylenediamine, ikoreshwa nkumuhuza wamabara, imiti ivura epoxy resin, inyongeramusaruro za peteroli, umuvuduko wa sima, M-dinitrobenzene nka sodium sulfide igice kimwe nacyo kuri M-nitroaniline. Kubara irangi rya orange base R, ni intera y'amabara ya azo hamwe na pigment organic.

Intangiriro

Nitrobenzene) nuruvange kama rushobora kuba kristaline yera ikomeye cyangwa amazi yumuhondo afite impumuro idasanzwe. Ibikurikira ni intangiriro kuri bimwe mubintu, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya nitrobenzene:

Ubwiza:

Nitrobenzene ntishobora gushonga mumazi ariko irashobora gushonga mumashanyarazi nka alcool na ethers.

Irashobora kuboneka na nitrati ya benzene, ikorwa mugukora benzene hamwe na aside nitricike yibanze.

Nitrobenzene ni uruganda ruhamye, ariko nanone iraturika kandi ifite umuriro mwinshi.

Koresha:

Nitrobenzene nigikoresho cyingenzi cyimiti kandi ikoreshwa cyane muri synthesis.

Nitrobenzene irashobora kandi gukoreshwa nkinyongera mumashanyarazi, amarangi hamwe.

Uburyo:

Uburyo bwo gutegura nitrobenzene buboneka ahanini na nitrification ya benzene. Muri laboratoire, benzene irashobora kuvangwa na acide ya nitricike hamwe na acide sulfurike yibanze, ikabyutsa ubushyuhe buke, hanyuma ikakaraba n'amazi akonje kugirango ibone nitrobenzene.

Amakuru yumutekano:

Nitrobenzene ni uburozi, kandi guhura cyangwa guhumeka umwuka wacyo birashobora kwangiza umubiri.

Nibintu byaka kandi biturika kandi bigomba kwirinda guhura ninkomoko yumuriro.

Ibikoresho byo kurinda umuntu nka gants zo kurinda hamwe na gogles bigomba kwambarwa mugihe ukoresha nitrobenzene, kandi hagomba kubungabungwa ibidukikije bihumeka neza.

Mugihe habaye impanuka cyangwa impanuka, hagomba gufatwa ingamba zikwiye kugirango zisukure kandi zijugunywe. Kurikiza amategeko n'amabwiriza ajyanye no guta neza imyanda yatanzwe.
