Awọn ohun-ini Ọja:
1.Benzene jẹ ọkan ninu awọn ohun elo aise ipilẹ ti o ṣe pataki julọ ati pe o jẹ aṣoju ti awọn hydrocarbons aromatic. O ni o ni a idurosinsin mefa-membered oruka be.
2.The akọkọ kemikali aati ni o wa afikun, aropo ati oruka-šiši lenu. Labẹ iṣe ti sulfuric acid ogidi ati acid nitric, o rọrun lati ṣe ipilẹṣẹ nitrobenzene nipasẹ ifarọpo. Fesi pẹlu ogidi sulfuric acid tabi fuming sulfuric acid lati dagba benzenesulfonic acid. Pẹlu awọn halides irin gẹgẹbi kiloraidi ferric bi ayase, iṣesi halogenation waye ni iwọn otutu kekere lati ṣe agbejade benzene halogenated. Pẹlu aluminiomu trichloride bi ayase, alkylation lenu pẹlu olefins ati halogenated hydrocarbons lati dagba alkylbenzene; ifaseyin acylation pẹlu acid anhydride ati acyl kiloraidi lati dagba acylbenzene. Ni iwaju ayase oxide vanadium, benzene jẹ oxidised nipasẹ atẹgun tabi afẹfẹ lati dagba anhydride maleic. Benzene kikan si 700 ° C sisan waye, ti o npese erogba, hydrogen ati kekere iye methane ati ethylene ati bẹbẹ lọ. Lilo Pilatnomu ati nickel bi awọn ayase, ifaseyin hydrogenation ni a ṣe lati gbejade cyclohexane. Pẹlu zinc kiloraidi bi ayase, iṣesi chloromethylation pẹlu formaldehyde ati hydrogen kiloraidi lati ṣe agbejade benzyl kiloraidi. Ṣugbọn oruka benzene jẹ iduroṣinṣin diẹ sii, fun apẹẹrẹ, pẹlu nitric acid, potasiomu permanganate, dichromate ati awọn oxidants miiran ko ṣe.
3.It ni o ni ga refractive ini ati ki o lagbara aromatic adun, flammable ati majele ti. Miscible pẹlu ethanol, ether, acetone, erogba tetrachloride, carbon disulfide ati acetic acid, die-die tiotuka ninu omi. Ti kii ṣe ibajẹ si awọn irin, ṣugbọn ipele kekere ti benzene ti o ni awọn idoti imi-ọjọ ninu bàbà ati diẹ ninu awọn irin ni ipa ipata ti o han gbangba. Liquid benzene ni ipa idinku, le gba nipasẹ awọ ara ati majele, nitorinaa yẹ ki o yago fun olubasọrọ pẹlu awọ ara.
4.Vapour ati afẹfẹ lati ṣe awọn apopọ bugbamu, opin bugbamu ti 1.5% -8.0% (iwọn didun).
5.Stability: Idurosinsin
6.Ewọ nkan elo:Strong oxidants, acids, halogens
7.Polymerisation ewu:Ti kii-polymerisation
Ohun elo ọja:
Awọn ohun elo aise kemikali ipilẹ, ti a lo bi awọn ohun mimu ati awọn itọsẹ benzene sintetiki, awọn turari, awọn awọ, awọn pilasitik, awọn oogun, awọn ibẹjadi, roba, abbl.
Awọn akọsilẹ Ibi ipamọ ọja:

2.Keep kuro lati ina ati orisun ooru.
3.The ipamọ otutu yẹ ki o ko koja 37 ° C.
4.Jeki apoti ti a ti pa.
5.O yẹ ki o wa ni ipamọ lọtọ lati awọn aṣoju oxidising, ati pe ko yẹ ki o dapọ.
6.Lo bugbamu-ẹri ina ati awọn ohun elo fentilesonu.
7.Prohibit awọn lilo ti darí itanna ati awọn irinṣẹ ti o wa ni rọrun lati se ina Sparks.
8.Agbegbe ibi ipamọ yẹ ki o wa ni ipese pẹlu awọn ohun elo itọju pajawiri jijo ati awọn ohun elo ti o dara.
