3,4-difluorotoluene ke motsoako oa manyolo o nang le foromo ea lik'hemik'hale C7H6F2. Ke mokelikeli o se nang 'mala o nang le monko o khethehileng o nkhang hamonate. E latelang ke tlhaloso e qaqileng ea tlhaho, tšebeliso, tokiso le tlhahisoleseding ea polokeho ea 3,4-difluorotoluene:
Tlhaho:
-Ponahalo: mokelikeli o se nang 'mala
-Tatso: Monko o monate o khethehileng
- Sebaka se belang: 96-97 ° C
- Boima: 1.145g/cm³
-Solubility: Ha e qhibilihe ka metsing, e qhibiliha ka har'a metsoako ea tlhaho
Sebelisa:
-3,4-difluorotoluene e ka sebelisoa e le ea bohlokoa lipakeng tsa motsoako oa manyolo.
-E ka sebelisoa ho kopanya lithethefatsi, dae, chefo e bolaeang likokoanyana le lik'hemik'hale tse ling.
-E ka boela ea sebelisoa e le thepa e tala bakeng sa thepa ea elektronike.
Mokhoa:
-3,4-difluorotoluene e na le mekhoa e mengata ea ho itokisa, e tloaelehileng ka ho fetisisa e fumanoa ka hydrogenation reduction reaction ea p-nitrotoluene. Mehato e khethehileng ke:
1. Ntlha ea pele, P-nitrotoluene e sebetsana le tšepe e feteletseng ea diammonium sulfate ho fumana p-nitrotoluene iron diammonium letsoai.
2. Hydrogen e eketsoa, 'me letsoai la p-nitrotoluene iron diammonium le tlas'a karabelo ea ho fokotsa ho ba teng ha tšepe ea tšepe.
3. Qetellong, 3,4-difluorotoluene e ile ea hloekisoa ka distillation.
Lintlha tsa Tšireletseho:
-3,4-difluorotoluene ka kakaretso e nkoa e batla e bolokehile tlas'a maemo a tloaelehileng a tšebeliso. Leha ho le joalo, ho ntse ho hlokahala ho latela mekhoa e nepahetseng ea tšireletso.
-Ke mokelikeli o tukang 'me o lokela ho qoba ho kopana le mollo le mocheso o phahameng.
- Li-gloves tse loketseng tse sireletsang, likhalase le liaparo tse sireletsang li khothalletsoa hore li sebelisoe le ho tšoaroa.
-E-ba hole le lijo, metsi le moo bana ba ka fihlang teng.
-Ha ho ka etsahala hore o hlahe ka phoso kapa o koetsoe ka phoso, batla thuso ea bongaka hang-hang 'me u bontše leibole ea sehlahisoa kapa setshelo ho mofani oa tlhokomelo ea bophelo.
