Product Properties:
1.Oxidised kune benzoic acid nemasimba ane oxidising agents akadai se potassium permanganate, potassium dichromate uye nitric acid. Benzoic asidhi inowanikwawo neoxidation nemhepo kana oxygen pamberi peiyo catalyst. Benzaldehyde inowanikwa ne oxidation ne manganese dioxide muhupo hwe sulfuric acid pa40 ° C kana pasi. Kuita kwekudzikisira kunokonzerwa nickel kana platinum kunogadzira methylcyclohexane. Toluene inopindirana nemahalojeni kuumba o- uye para-halogenated toluene ichishandisa aluminum trichloride kana ferric chloride sezvinokonzeresa. Pasi pekupisa uye chiedza, inopindirana nema halogens kuita benzyl halide. Kuita ne nitric acid kunogadzira o- uye para-nitrotoluene. Kana nitrified neakasanganiswa acids (sulphuric acid + nitric acid) 2,4-dinitrotoluene inogona kuwanikwa; inoenderera mberi nitration inoburitsa 2,4,6-trinitrotoluene (TNT). Sulfoneation ye toluene ine concentrated sulfuric acid kana fuming sulfuric acid inogadzira o- uye para-methylbenzenesulphonic acid. Pasi pekuita kwealuminum trichloride kana boron trifluoride, toluene inopinda mualkylation ine halogenated hydrocarbons, olefins, uye doro kupa musanganiswa wealkyl toluene. Toluene inopindirana ne formaldehyde uye hydrochloric acid mu chloromethylation reaction kuti ibudise o- kana para-methylbenzyl chloride.
2.Kugadzikana: Kugadzikana
3.Zvinhu zvinorambidzwa:Strong oxidants, asidhi, halogens
4.Polymerization ngozi:Kwete-polymerization
Product Application:
1.Iyo inoshandiswa zvakanyanya se organic solvent uye raw material yemishonga yekugadzira, pendi, resin, dyestuff, zvinoputika uye pesticide.
2.Toluene inogona kushandiswa seyakasvibirira kugadzira benzene uye mamwe akawanda emakemikari zvigadzirwa. Zvakadai sepende, varnishes, lacquers, adhesives uye inki yekugadzira indasitiri uye iyo yakaonda inoshandiswa mukugadzirwa kwemvura, resin solvents; makemikari uye kugadzira zvinonyungudutsa. Iyo zvakare ndiyo yakabikwa yemakemikari synthesis. Inogonawo kushandiswa sechinhu chinosanganisa mupeturu kuwedzera octane, uye sechinhu chinonyungudutsa pendi, ingi uye nitrocellulose. Pamusoro pezvo, toluene ine kunyungudika kwakanakisa kwe organic matter, i organic solvent ine mashandisirwo akawanda. Toluene iri nyore kuchenesa, kugadzira benzene & mdash; chloromethane kana benzene trichloromethane, iwo akanaka zvinonyungudutsa paindasitiri; zvakare zviri nyore kuita nitrate, kugadzira p-nitrotoluene kana o-nitrotoluene, iwo magadzirirwo edhayi; zviri nyore zvakare sulphonate, inogadzira o-toluenesulphonic acid kana p-toluenesulphonic acid, iwo magadzirirwo ekugadzira madhayi kana saccharine kugadzirwa. Toluene vapor inosanganiswa nemhepo kuita zvinhu zvinoputika, saka inogona kugadzira TST inoputika.
3.Leaching agent yezvinomera zvinorimwa. Inoshandiswa muhuwandu hukuru sechinhu chinonyungudutsa uye sekuwedzera kune high-octane peturu.
4.Inoshandiswa seanalytical reagent, yakadai semagetsi, kubvisa uye kuparadzanisa vashandi, chromatographic reagents. Inoshandiswawo semumiririri wekuchenesa, uye inoshandiswa mudhayi, zvinonhuwira, benzoic acid uye mamwe organic synthesis.
5.Inoshandiswa mukugadzirwa kwedoped peturu uye sechinhu chikuru chekugadzirwa kwetoluene derivatives, zvinoputika, dhayi pakati, zvinodhaka nezvimwe zvakadaro.
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.
