Izici Zomkhiqizo:
I-1.I-benzene ingenye yezinto ezibalulekile eziyisisekelo ze-organic futhi imele ama-hydrocarbon anephunga elimnandi. Inesakhiwo esizinzile esinamalungu ayisithupha.
2.Ukusabela kwamakhemikhali okuyinhloko ukuhlanganisa, ukufaka esikhundleni kanye nokuphendula ngokuvula indandatho. Ngaphansi kwesenzo se-concentrated sulfuric acid kanye ne-nitric acid, kulula ukukhiqiza i-nitrobenzene ngokusabela esikhundleni. Isabela nge-sulfuric acid egxilile noma i-sulfuric acid evuthayo ukuze yakhe i-benzenesulfonic acid. Ngama-metal halides afana ne-ferric chloride njenge-catalyst, ukusabela kwe-halogenation kwenzeka ekushiseni okuphansi ukukhiqiza i-halogenated benzene. Nge-aluminium trichloride njenge-catalyst, ukusabela kwe-alkylation nge-olefin nama-halogenated hydrocarbons ukwakha i-alkylbenzene; ukusabela kwe-acylation nge-asidi anhydride ne-acyl chloride ukwenza i-acylbenzene. Lapho kukhona i-vanadium oxide catalyst, i-benzene ikhishwa umoya-mpilo noma umoya ukuze yakhe i-anhydride ye-maleic. I-Benzene ishisa ku-700 ° C ukuqhekeka kwenzeka, ikhiqiza i-carbon, i-hydrogen kanye nenani elincane le-methane ne-ethylene nokunye. Kusetshenziswa iplatinamu ne-nickel njengama-catalyst, ukusabela kwe-hydrogenation kwenziwa ukuze kukhiqizwe i-cyclohexane. Nge-zinc chloride njenge-catalyst, ukusabela kwe-chloromethylation nge-formaldehyde ne-hydrogen chloride ukukhiqiza i-benzyl chloride. Kodwa indandatho ye-benzene izinzile, isibonelo, i-nitric acid, i-potassium permanganate, i-dichromate nezinye i-oxidants ayiphenduli.
3.Inomphumela ophezulu we-refractive kanye ne-flavour ephunga elimnandi, evuthayo futhi inobuthi. Ixubene ne-ethanol, i-ether, i-acetone, i-carbon tetrachloride, i-carbon disulfide ne-acetic acid, inyibilika kancane emanzini. Ayigqwali ezinsimbi, kodwa izinga eliphansi le-benzene eliqukethe ukungcola kwesulfure kukhopha nezinye izinsimbi zinomphumela wokugqwala osobala. I-benzene ewuketshezi inomphumela wokuwohloka, ingamuncwa isikhumba kanye nobuthi, ngakho-ke kufanele ugweme ukuthintana nesikhumba.
I-4.I-vapour kanye nomoya ukwenza izingxube eziqhumayo, umkhawulo wokuqhuma we-1.5% -8.0% (ivolumu).
5.Ukuzinza: Ukuzinza
6.Izinto ezingavunyelwe:Sama-oxidants aqinile, ama-asidi, ama-halogens
7.Ingozi yePolymerization:I-Non-pi-olymerization
Isicelo somkhiqizo:
Izinto zokusetshenziswa zamakhemikhali eziyisisekelo, ezisetshenziswa njengezincibilikisi nezinto eziphuma ku-benzene zokwenziwa, izinongo, odayi, amapulasitiki, amakhemisi, iziqhumane, irabha, njll.
Amanothi Okugcina Umkhiqizo:
1.Gcina endaweni epholile, nengena umoya.
2. Gcina kude nomlilo kanye nomthombo wokushisa.
3.Izinga lokushisa lokugcina akufanele lidlule ku-37°C.
4.Gcina isitsha sivaliwe.
5.Kufanele igcinwe ngokuhlukana nama-oxidising agents, futhi akufanele neze ixutshwe.
6.Sebenzisa izibani ezingaqhumi kanye nezindawo zokungenisa umoya.
7.Vimbela ukusetshenziswa kwemishini namathuluzi alula ukwenza izinhlansi.
I-8.Indawo yokugcina kufanele ifakwe imishini yokwelapha izimo eziphuthumayo ezivuzayo kanye nezinto zokukhosela ezifanele.
