Ibicuruzwa:
1.Benzene nimwe mubintu byingenzi byibanze byibanze kandi ni uhagarariye hydrocarbone nziza. Ifite imiterere itandatu igizwe nabanyamuryango.
2.Imiti nyamukuru yimiti niyongera, gusimbuza no gufungura impeta. Mubikorwa bya acide sulfurike yibanze hamwe na acide ya nitric, biroroshye kubyara nitrobenzene mugusimbuza reaction. Kora hamwe na acide sulfurike yibanze cyangwa gusohora aside sulfurike kugirango ukore aside benzenesulfonic. Hamwe nicyuma nka chloride ferricike nka catalizator, reaction ya halogenation ibaho mubushyuhe buke kugirango itange benzene ya halogene. Hamwe na aluminium trichloride nka catalizator, reaction ya alkylation hamwe na olefine na hydrocarbone ya halogene ikora alkylbenzene; acylation reaction hamwe na acide anhydride na acili chloride kugirango ikore acylbenzene. Imbere ya catisale ya vanadium oxyde, benzene ihindurwamo ogisijeni cyangwa umwuka kugirango ikore anhydride yumugabo. Benzene yashyutswe kugeza kuri 700 ° C gucika bibaho, bikabyara karubone, hydrogène hamwe na metani nkeya na etilene nibindi. Ukoresheje platine na nikel nka catalizator, reaction ya hydrogenation ikorwa kugirango cyclohexane. Hamwe na chloride ya zinc nka catalizator, chloromethylation reaction hamwe na fordehide na hydrogen chloride kugirango bitange benzyl chloride. Ariko impeta ya benzene irahagaze neza, kurugero, hamwe na acide ya nitric, potasiyumu permanganate, dichromate nizindi okiside ntizifata.
3.Ifite imitungo myinshi yangiritse kandi uburyohe bukomeye bwa aromatic, yaka kandi ifite uburozi. Ntibishobora gukoreshwa na Ethanol, ether, acetone, tetrachloride ya karubone, karubone disulfide na acide acike, bigashonga gato mumazi. Ntibishobora kwangirika kwibyuma, ariko urwego rwo hasi rwa benzene irimo umwanda wa sulfure kumuringa hamwe nibyuma bimwe bifite ingaruka zigaragara. Amazi ya benzene agira ingaruka mbi, irashobora kwinjizwa nuruhu nuburozi, bityo rero ugomba kwirinda guhura nuruhu.
4.Umwuka numwuka kugirango ube uruvange ruturika, igipimo cyo guturika cya 1.5% -8.0% (ingano).
5.Guhungabana: Birahamye
6.Ibintu bibujijwe:Strong oxydeans, acide, halogene
7.Impanuka ya polimerisation:Ntabwo polymerisation
Gusaba ibicuruzwa:
Ibikoresho fatizo bya shimi, bikoreshwa nkibishishwa hamwe nimbuto zikomoka kuri benzene, ibirungo, amarangi, plastiki, imiti, ibisasu, reberi, nibindi.
Inyandiko zibika ibicuruzwa:
1.Bika mububiko bukonje, buhumeka.
2.Komeza kure yumuriro nubushyuhe.
3.Ubushyuhe bwo kubika ntibugomba kurenga 37 ° C.
4.Komeza ikintu gifunze.
5.Bigomba kubikwa bitandukanye na okiside, kandi ntibigomba na rimwe kuvangwa.
6.Koresha ibikoresho biturika biturika kandi bihumeka.
7.Kubuza gukoresha ibikoresho bya mashini nibikoresho byoroshye kubyara ibishashi.
8.Ahantu ho kubika hagomba kuba hafite ibikoresho byihutirwa byihutirwa nibikoresho byubuhungiro.
