Thepa ea Sehlahisoa:
1.Benzene ke e 'ngoe ea lintho tsa bohlokoa ka ho fetisisa tsa motheo tsa lihlahisoa tse tala 'me ke moemeli oa li-hydrocarbon tse nkhang hamonate. E na le sebopeho se tsitsitseng sa litho tse tšeletseng.
2.Liphetoho tse ka sehloohong tsa lik'hemik'hale ke ho phaella, ho fetola le ho bula lesale. Tlas'a ketso ea sulfuric acid le nitric acid, ho bonolo ho hlahisa nitrobenzene ka karabelo ea sebaka. E arabela ka acid e ngata ea sulfuric kapa sulfuric acid e monko ho etsa benzenesulfonic acid. Ka metal halides tse kang ferric chloride e le catalyst, halogenation reaction e etsahala ka mocheso o tlase ho hlahisa halogenated benzene. Ka aluminium trichloride e le catalyst, alkylation reaction with olefin le halogenated hydrocarbons ho etsa alkylbenzene; acylation reaction ka acid anhydride le acyl chloride ho etsa acylbenzene. Ka pel'a vanadium oxide catalyst, benzene e tšeloa ka oksijene kapa moea ho etsa maleic anhydride. Benzene e futhumetse ho 700 ° C ho phunyeha ho etsahala, ho hlahisa carbon, hydrogen le palo e nyenyane ea methane le ethylene joalo-joalo. Ho sebelisoa platinum le nickel e le li-catalyst, hydrogenation reaction e etsoa ho hlahisa cyclohexane. Ka zinki chloride e le sesosa, karabelo ea chloromethylation ka formaldehyde le hydrogen chloride ho hlahisa benzyl chloride. Empa selikalikoe sa benzene se tsitsitse haholoanyane, ka mohlala, ka nitric acid, potasiamo permanganate, dichromate le li-oxidants tse ling ha li sebetse.
3.E na le thepa e phahameng ea refractive le tatso e nkhang hamonate, e tukang ebile e chefo. E kopane le ethanol, ether, acetone, carbon tetrachloride, carbon disulfide le acetic acid, e qhibilihang hanyenyane metsing. Ha e senye litšepe, empa boemo bo tlase ba benzene e nang le litšila tsa sebabole holim'a koporo le litšepe tse ling li na le matla a ho senya. Mokelikeli oa benzene o na le phello e senyang, e ka monngoa ke letlalo le chefo, kahoo e lokela ho qoba ho kopana le letlalo.
4.Mouoane le moea ho theha metsoako e phatlohang, moeli oa ho phatloha oa 1.5% -8.0% (volume).
5.Botsitso: E tsitsitseng
6. Lintho tse thibetsoeng:Sli-oxidants tse matla, acid, halogens
7. Kotsi ea polymerization:E seng leqolymerization
Sesebelisoa sa Sehlahisoa:
Lisebelisoa tsa mantlha tsa lik'hemik'hale, tse sebelisoang e le lihlapolli le lihlahisoa tsa maiketsetso tsa benzene, linoko, lidae, lipolasetiki, meriana, liqhomane, rabara, joalo-joalo.
Lintlha tsa polokelo ea Sehlahisoa:
1.E boloke sebakeng sa polokelo se pholileng, se nang le moea o pholileng.
2.Kena hole le mollo le mohloli oa mocheso.
3.Mocheso oa polokelo ha oa lokela ho feta 37°C.
4. Boloka setshelo se tiisitsoe.
5.E lokela ho bolokoa ka thoko ho li-oxidising agents, 'me ha ea lokela ho tsoakoa.
6.Sebelisa mabone a thibelang ho phatloha le lisebelisoa tsa moea.
7.Hanela tšebeliso ea lisebelisoa tsa mechine le lisebelisoa tse bonolo ho hlahisa litlhase.
8.Sebaka sa polokelo se lokela ho ba le lisebelisoa tsa phekolo ea tšohanyetso tse lutlang le lisebelisoa tse loketseng tsa bolulo.
