Isingeniso
I-3,4-difluorotoluene iyinhlanganisela ye-organic ene-chemical formula C7H6F2. Iwuketshezi olungenambala olunephunga elimnandi elikhethekile. Okulandelayo incazelo eningiliziwe yemvelo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha lwe-3,4-difluorotoluene:
Imvelo:
-Ukubukeka: uketshezi olungenambala
-Taste: Iphunga elimnandi elikhethekile
-Indawo yokubilisa: 96-97 ° C
-Ukuminyana: 1.145g/cm³
-I-Solubility: Ayincibiliki emanzini, incibilika kuzincibilikisi zemvelo
Sebenzisa:
-3,4-difluorotoluene ingasetshenziswa njengento ebalulekile ephakathi ku-organic synthesis.
-Ingasetshenziselwa ukuhlanganisa izidakamizwa, odayi, izibulala-zinambuzane namanye amakhemikhali.
-Ingasetshenziswa futhi njengento eluhlaza yezinto zikagesi.
Indlela:
-3,4-difluorotoluene inezindlela eziningi zokulungiselela, okuvamile kutholakala ngokusabela kokunciphisa i-hydrogenation ye-p-nitrotoluene. Izinyathelo ezithile yilezi:
1. Okokuqala, i-P-nitrotoluene isabela ngensimbi eyeqile i-diammonium sulfate ukuze ithole usawoti we-p-nitrotoluene iron diammonium.
2. I-Hydrogen yengezwa, futhi i-p-nitrotoluene iron diammonium usawoti ingaphansi kokusabela kokunciphisa phambi kwe-catalyst yensimbi.
3. Ekugcineni, i-3,4-difluorotoluene yahlanzwa nge-distillation.
Ulwazi Lokuphepha:
-3,4-difluorotoluene ngokuvamile ibhekwa njengephephile uma kuqhathaniswa ngaphansi kwezimo ezivamile zokusetshenziswa. Nokho, kusadingeka ukuhambisana nezinqubo zokuphepha ezifanele.
-Kuwuketshezi oluvuthayo futhi kufanele kugweme ukuthintana nomlilo kanye nokushisa okuphezulu.
-Amagilavu okuzivikela afanelekile, izibuko nezingubo zokuzivikela kuyanconywa ukuthi zisetshenziswe futhi ziphathwe.
-Deda nokudla, amanzi kanye nokufinyelelwa yizingane.
-Esimeni sokuchayeka ngephutha noma ukugwinya ngephutha, funa usizo lwezokwelapha ngokushesha futhi ubonise ilebula yomkhiqizo noma isiqukathi kumhlinzeki wezempilo.
