Product Properties:
1.Benzene imwe yezvakakosha zvakakosha zveorganic raw materials uye inomiririra anonhuwirira hydrocarbons. Iine yakagadzikana nhanhatu-nhengo mhete chimiro.
2.Iyo huru yemakemikari maitiro ndeyekuwedzera, kutsiva uye mhete-kuvhura reaction. Pasi pekuita kwe concentrated sulfuric acid uye nitric acid, zviri nyore kugadzira nitrobenzene nekutsiva reaction. React neconcentrated sulfuric acid kana fuming sulfuric acid kuita benzenesulfonic acid. Nesimbi halides senge ferric chloride secatalyst, halogenation reaction inoitika pakadzika tembiricha kuburitsa halogenated benzene. Nealuminium trichloride se catalyst, alkylation reaction ine olefins uye halogenated hydrocarbons kuumba alkylbenzene; acylation reaction ne acid anhydride uye acyl chloride kugadzira acylbenzene. Pamberi pevanadium oxide catalyst, benzene yakasvibiswa neokisijeni kana mweya kuti iite maleic anhydride. Benzene inopisa kusvika 700 ° C kutsemuka kunoitika, kugadzira kabhoni, hydrogen uye diki methane uye ethylene zvichingodaro. Kushandisa platinum uye nickel sezvikonzero, hydrogenation reaction inoitwa kugadzira cyclohexane. Ne zinc chloride secatalyst, chloromethylation reaction ine formaldehyde uye hydrogen chloride kugadzira benzyl chloride. Asi mhete ye benzene yakanyanya kugadzikana, semuenzaniso, ine nitric acid, potassium permanganate, dichromate uye mamwe oxidants haaite.
3.Ine yakakwirira refractive pfuma uye yakasimba inonhuhwirira flavour, inopfuta uye ine chepfu. Kusanganiswa ne ethanol, ether, acetone, carbon tetrachloride, carbon disulfide uye acetic acid, inonyungudika zvishoma mumvura. Isingaori kusimbi, asi giredhi rezasi rebenzene rine tsvina yesarufa pamhangura uye mamwe masimbi ane corrosive mhedzisiro. Liquid benzene ine degreasing effect, inogona kutorwa neganda uye chepfu, saka inofanira kudzivirira kubata neganda.
4.Vapour nemhepo kuti iite misanganiswa inoputika, kuputika kwekuputika kwe1.5% -8.0% (volume).
5.Kugadzikana: Kugadzikana
6.Zvinhu zvinorambidzwa:Strong oxidants, asidhi, halogens
7.Polymerization ngozi:Kwete-polymerization
Product Application:
Chekutanga kemikari raw materials, anoshandiswa sezvinonyungudutsa uye zvekugadzira benzene derivatives, zvinonhuwira, dhayi, mapurasitiki, mishonga, zvinoputika, rabha, nezvimwe.
Chigadzirwa Chekuchengetedza Notes:
1.Chengeta munzvimbo inotonhorera, ine mhepo yekuchengetera mhepo.
2.Gara kure nemoto uye kupisa sosi.
3.Tembiricha yekuchengetera haifanire kudarika 37°C.
4.Chengetedza mudziyo wakavharwa.
5.Inofanira kuchengetwa zvakasiyana kubva kune oxidising agents, uye haifaniri kumbosanganiswa.
6.Shandisa kuputika-kuvhenekera uye zvivako zvemhepo.
7.Kurambidza kushandiswa kwemichina yemagetsi uye zvishandiso zviri nyore kugadzira mazhenje.
8.Nzvimbo yekuchengetera inofanirwa kuve yakashongedzerwa nekudonha kwechimbichimbi michina yekurapa uye yakakodzera pekugara zvinhu.
