Nhanganyaya

Benzene imvura isina ruvara uye inoonekera ine kunhuhwirira kwakakosha. Iyi inotevera sumo yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza benzene:

Hunhu:

1. Benzene inonyanya kushanduka uye inopisa, uye inogona kugadzira musanganiswa unoputika neokisijeni mumhepo.

2. Iro organic solvent inogona kunyungudutsa organic matter yakawanda, asi isinganyungudike mumvura.

3. Benzene isanganiswa inonhuhwirira ine chimiro chemakemikari yakagadzikana.

4. Kemikari yebenzene yakagadzikana uye haisi nyore kurwiswa neacid kana alkali.

Shandisa:

1. Benzene inoshandiswa zvakanyanya seyakagadzirwa neindasitiri yekugadzira mapurasitiki, rabha, dhayi, mafibhi ekugadzira, nezvimwe.

2. Iyo yakakosha kubva muindasitiri yepetrochemical, inoshandiswa kugadzira phenol, benzoic acid, aniline uye mamwe makomisheni.

3. Benzene inowanzoshandiswa sechinhu chinonyungudutsa cheorganic synthesis reactions.

Nzira:

1. Inowanikwa sechigadzirwa-chigadzirwa mukunatswa kwepetroleum.

2. Inowanikwa nekugadzirisa kwekushaya mvura kwe phenol kana kuputika kwemarasha tar.

Zvekuchengetedza

1. Benzene chinhu chine muchetura, uye kubatwa kwenguva refu kana kufemerwa nemhepo yakawandisa yebenzene vapor zvinokonzeresa njodzi dzehutano kumuviri wemunhu, kusanganisira carcinogenicity.

2. Paunenge uchishandisa benzene, zvinodikanwa kuchengetedza mhepo yakanaka yemhepo kuti uone kuti kuvhiyiwa kunoitwa munzvimbo yakakodzera.

3. Dzivisa kubatwa kweganda uye kufemera mupfuhwira webenzene, uye pfeka zvinhu zvinozvidzivirira zvakaita semagirovhosi ekudzivirira nezvinofemesa.

4. Kudya kana kunwa zvinhu zvine benzene zvinounza muchetura, uye nzira dzekuchengetedza kuchengetedza dzinofanira kunyatsocherechedzwa.

5. Marara ebenzene netsvina inosanganisirwa mubenzene inofanira kuraswa zvichitevedza mitemo nemirau yakakodzera kudzivirira kusvibiswa kwezvakatipoteredza nekukuvadza.
