Katundu:
1.Benzene ndi imodzi mwazinthu zofunika kwambiri zopangira organic ndipo imayimira ma hydrocarbon onunkhira. Ili ndi mphete yokhazikika yokhala ndi mamembala asanu ndi limodzi.
2.Zochita zazikulu zamakina ndizowonjezera, kulowetsa ndi kutsegulira kwa mphete. Pansi pa zochita za sulfuric acid ndi nitric acid, ndizosavuta kupanga nitrobenzene polowa m'malo. Amachitani ndi sulfuric acid kapena fuming sulfuric acid kupanga benzenesulfonic acid. Ndizitsulo zachitsulo monga ferric chloride monga chothandizira, halogenation reaction imapezeka pa kutentha kochepa kuti ipange halogenated benzene. Ndi aluminium trichloride monga chothandizira, alkylation reaction ndi olefins ndi halogenated hydrocarbons kupanga alkylbenzene; acylation reaction ndi asidi anhydride ndi acyl chloride kupanga acylbenzene. Pamaso pa vanadium oxide catalyst, benzene amapangidwa ndi okosijeni kapena mpweya kuti apange maleic anhydride. Benzene imatenthedwa mpaka 700 ° C kusweka kumachitika, kutulutsa mpweya, haidrojeni ndi methane pang'ono ndi ethylene ndi zina zotero. Pogwiritsa ntchito platinamu ndi nickel monga chothandizira, hydrogenation reaction imachitika kuti ipange cyclohexane. Ndi zinki kolorayidi monga chothandizira, chloromethylation anachita ndi formaldehyde ndi hydrogen kolorayidi kupanga benzyl kolorayidi. Koma mphete ya benzene imakhala yokhazikika, mwachitsanzo, ndi nitric acid, potaziyamu permanganate, dichromate ndi ma okosijeni ena samachita.
3.Ili ndi katundu wambiri wotsitsimula komanso kununkhira kwamphamvu, kuyaka komanso poizoni. Zosakaniza ndi ethanol, ether, acetone, carbon tetrachloride, carbon disulfide ndi acetic acid, sungunuka pang'ono m'madzi. Zosawononga ku zitsulo, koma benzene yotsika yokhala ndi zonyansa za sulfure pa mkuwa ndi zitsulo zina zimakhala ndi mphamvu zowononga. Zamadzimadzi benzene ndi degreasing zotsatira, akhoza kuyamwa ndi khungu ndi poizoni, choncho kupewa kukhudzana ndi khungu.
4.Vapour ndi mpweya kupanga zosakaniza zophulika, malire a kuphulika kwa 1.5% -8.0% (volume).
5.Kukhazikika: Kukhazikika
6. Zinthu zoletsedwa:Strong okosijeni, zidulo, halogens
7. Polymerization ngozi:Non-polymerization
Ntchito Yogulitsa:
Basic mankhwala zopangira, ntchito monga solvents ndi kupanga zotumphukira benzene, zonunkhira, utoto, mapulasitiki, mankhwala, zophulika, labala, etc.
Zolemba Zosungira:
1.Sungani m'nyumba yosungiramo zoziziritsa komanso mpweya wabwino.
2. Khalani kutali ndi moto ndi gwero la kutentha.
3.Kutentha kosungirako kusapitirire 37°C.
4.Sungani chidebe chosindikizidwa.
5.Iyenera kusungidwa mosiyana ndi oxidizing agents, ndipo sayenera kusakanikirana.
6.Gwiritsani ntchito zounikira zosaphulika ndi mpweya wabwino.
7.Letsani kugwiritsa ntchito zida zamakina ndi zida zomwe zimakhala zosavuta kupanga zopsereza.
8.Malo osungira ayenera kukhala ndi zida zowonongeka zowonongeka ndi zipangizo zoyenera zogona.
