Intangiriro

Benzidine (izwi kandi nka diphenylamine) ni ifumbire mvaruganda. Ibikurikira nintangiriro yimiterere yabyo, imikoreshereze, uburyo bwo gukora namakuru yumutekano:

Ubwiza:

- Kugaragara: Benzidine ni umweru kugeza umuhondo wijimye wijimye.

- Gukemura: kudashonga mumazi, gushonga mumashanyarazi nka alcool, ethers, nibindi.

- Ikimenyetso: Ni electrophile ifite imiterere yo gusimbuza electrophilique.

Koresha:

- Benzidine ikoreshwa cyane mubijyanye na synthesis organique. Irashobora gukoreshwa nkibikoresho fatizo hamwe nogukora hagati yimiti nkamabara, pigment, plastike, nibindi.

Uburyo:

- Benzidine isanzwe itegurwa no kugabanya dinitrobiphenyl, kurandura imirasire ya haloaniline, nibindi.

- Uburyo bugezweho bwo gutegura burimo synthesis organic ya amine aromatic, nka reaction ya substrate diphenyl ether hamwe na amino alkane.

Amakuru yumutekano:

- Benzidine ni uburozi kandi irashobora gutera uburakari no kwangiza umubiri wumuntu.

- Mugihe ukoresha benzidine, ugomba kwitonda kugirango wirinde guhura nuruhu no guhumeka, kandi ibikoresho birinda nka gants, ibirahure birinda, hamwe na masike yo gukingira bigomba kwambara nibiba ngombwa.

- Iyo benzidine ihuye nuruhu cyangwa amaso, igomba kwozwa ako kanya n'amazi menshi.

- Mugihe ubitse kandi ukoresha benzidine, witondere kwirinda guhura nibintu kama na okiside kugirango wirinde umuriro cyangwa guturika.
