Abubuwan Samfura:
1.Benzene yana daya daga cikin mahimman kayan albarkatun halitta na asali kuma shine wakilin hydrocarbons na aromatic. Yana da tsayayyen tsarin zobe mai mutum shida.
2.The main sinadaran halayen ne Bugu da kari, maye da kuma zobe-bude amsa. Ƙarƙashin aikin sulfuric acid da nitric acid, yana da sauƙi don samar da nitrobenzene ta hanyar maye gurbin. Yi amsa tare da maida hankali sulfuric acid ko fuming sulfuric acid don samar da benzenesulfonic acid. Tare da halides na ƙarfe irin su ferric chloride a matsayin mai haɓakawa, halayen halogenation yana faruwa a ƙananan zafin jiki don samar da benzene halogenated. Tare da aluminum trichloride a matsayin mai kara kuzari, alkylation dauki tare da olefins da halogenated hydrocarbons don samar da alkylbenzene; amsawar acylation tare da acid anhydride da acyl chloride don samar da acylbenzene. A gaban vanadium oxide catalyst, benzene yana oxidised ta oxygen ko iska don samar da maleic anhydride. Benzene mai zafi zuwa 700 ° C fashe yana faruwa, yana haifar da carbon, hydrogen da ƙaramin adadin methane da ethylene da sauransu. Yin amfani da platinum da nickel a matsayin masu haɓakawa, ana aiwatar da halayen hydrogenation don samar da cyclohexane. Tare da zinc chloride a matsayin mai kara kuzari, chloromethylation dauki tare da formaldehyde da hydrogen chloride don samar da benzyl chloride. Amma zoben benzene ya fi kwanciyar hankali, alal misali, tare da nitric acid, potassium permanganate, dichromate da sauran oxidants ba sa amsawa.
3.It yana da high refractive dukiya da karfi kamshi dandano, flammable kuma mai guba. Miscible tare da ethanol, ether, acetone, carbon tetrachloride, carbon disulfide da acetic acid, dan kadan mai narkewa cikin ruwa. Mara lahani ga karafa, amma ƙananan sa na benzene mai ɗauke da ƙazantattun sulfur akan tagulla da wasu karafa suna da tasirin lalata. Liquid benzene yana da sakamako mai raguwa, fata da guba za a iya sha, don haka ya kamata ku guje wa haɗuwa da fata.
4.Vapour da iska don samar da abubuwan fashewa, iyakar fashewar 1.5% -8.0% (girma).
5.Kwarai: Kwanciyar hankali
6. Abubuwan da aka haramta:Soxidants, halogens, acid
7. Hadarin polymerisation:Ba polymerisation
Aikace-aikacen samfur:
Kayan kayan masarufi na asali, ana amfani da su azaman kaushi da abubuwan da aka samo asali na benzene, kayan yaji, rini, robobi, magunguna, fashewa, roba, da sauransu.
Bayanan Ajiye samfur:
1.Ajiye a cikin dakin ajiya mai sanyi, mai iska.
2.Kiyaye daga wuta da tushen zafi.
3.The ajiya zafin jiki kada ya wuce 37 ° C.
4.Kiyaye akwati a rufe.
5.Ya kamata a adana shi daban daga magungunan oxidising, kuma kada a taɓa haɗuwa.
6.Yi amfani da hasken wuta-proof da wuraren samun iska.
7.Hana yin amfani da kayan aikin injiniya da kayan aiki masu sauƙi don haifar da tartsatsi.
8.Yankin ajiya ya kamata a sanye shi da kayan aikin gaggawa na gaggawa da kayan aiki masu dacewa.
