Benzene ni uruganda rutoroshye kubora. Iyo yitwaye nibindi bintu bya shimi, imiterere shingiro yayo ntigihinduka, gusa atome ya hydrogen mumpeta ya benzene isimburwa nandi matsinda. Umwuka wa benzene urashobora gukora imvange iturika hamwe numwuka. Amazi ya Benzene yoroshye kuruta amazi, ariko imyuka yayo iremereye kuruta umwuka. Biroroshye cyane gutera umuriro no guturika imbere yubushyuhe bwinshi cyangwa umuriro ufunguye. Umwuka wa Benzene urashobora gukwirakwira kure, guhura ninkomoko yo gutwikwa, hamwe numuriro ugana inyuma. Benzene ikunda kubyara no kwegeranya amashanyarazi ahamye. Imyitwarire ya benzene ihuye na okiside irakomeye. Benzene ntishobora gushonga mumazi, ariko irashobora gushonga muri alcool, ether, acetone, chloroform, lisansi, carbone disulfide nibindi byangiza umubiri.
Koresha Ibikoresho fatizo bya shimi, bikoreshwa nkibishishwa hamwe nimbuto zikomoka kuri benzene, ibirungo, amarangi, plastiki, imiti, ibisasu, reberi, nibindi.

Intangiriro

Benzene ni ibara ritagira ibara kandi rifite umucyo ufite impumuro idasanzwe. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya benzene:

 

Ubwiza:

1. Benzene ihindagurika cyane kandi irashya, kandi irashobora gukora imvange iturika hamwe na ogisijeni mu kirere.

2. Ni umusemburo kama ushobora gushonga ibintu byinshi kama, ariko ntibishonga mumazi.

3. Benzene nuruvange rwimpumuro nziza yimiti ihamye.

4. Imiterere yimiti ya benzene irahagaze kandi ntabwo byoroshye kwibasirwa na aside cyangwa alkali.

 

Koresha:

1. Benzene ikoreshwa cyane nkibikoresho fatizo byinganda mu gukora plastiki, reberi, amarangi, fibre synthique, nibindi.

2.Ni inkomoko y'ingenzi mu nganda za peteroli, ikoreshwa mu gukora fenol, aside benzoic, aniline n'ibindi bikoresho.

3. Benzene nayo ikoreshwa muburyo bwo gukemura ibibazo bya synthesis.

 

Uburyo:

1. Biboneka nkibicuruzwa muburyo bwo gutunganya peteroli.

2. Biboneka kubwo kubura umwuma wa fenol cyangwa kumenagura amakara.

 

Amakuru yumutekano:

1.

2. Iyo ukoresheje benzene, birakenewe gukomeza uburyo bwiza bwo guhumeka kugirango ibikorwa bikorwe ahantu heza.

3. Irinde guhura nuruhu no guhumeka umwuka wa benzene, kandi wambare ibikoresho byokwirinda nka gants zo gukingira hamwe nubuhumekero.

4. Kurya cyangwa kunywa ibintu birimo benzene bizatera uburozi, kandi inzira zumutekano zigomba kubahirizwa cyane.
