Selelekela
1,3-Difluorobenzene ke motsoako oa lintho tse phelang. Se latelang ke selelekela se felletseng sa thepa, ts'ebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea 1,3-difluorobenzene:
Boleng:
1,3-Difluorobenzene ke motsoako oa organofluorine o nang le botsitso bo phahameng ba lik'hemik'hale. Ha e chese empa e sebetsa ka li-oxidizing agents tse matla. 1,3-Difluorobenzene e qhibiliha ka har'a metsoako e tloaelehileng ea tlhaho e kang ethanol, ether le chloroform, 'me ha e qhibilihe metsing.
Sebelisa:
1,3-difluorobenzene e na le boleng bo itseng ba ts'ebeliso ho organic synthesis. E ka sebelisoa e le reagent ea karabelo ho organic synthesis, mohlala e le reagent ea fluorinating bakeng sa metsoako e nkhang hamonate. 1,3-difluorobenzene e ka boela ea sebelisoa ha ho etsoa lisebelisoa tsa fluorescent, ho lokisoa ha lisebelisoa tsa organic optoelectronic le masimo a mang.
Mokhoa:
1,3-Difluorobenzene e ka lokisoa ka fluorination ea benzene. Mekhoa ea ho itokisa e sebelisoang ka tloaelo ke hydrogen fluoride e le sesebelisoa sa fluorinating kapa tšebeliso ea ferrous fluoride complexes bakeng sa karabelo ea fluorination.
Lintlha tsa Tšireletseho:
Mehato e latelang ea ts'ireletso e lokela ho nkuoa ha u sebelisa 1,3-difluorobenzene:
1.1,3-Difluorobenzene e na le chefo e itseng, e ka bakang kotsi ha e kopana le letlalo, ho hema ka moea oa khase kapa ho kenngoa ka phoso. Lisebelisoa tse loketseng tsa ho itšireletsa tse kang liatlana, liaparo tse sireletsang mahlo, le limaske li lokela ho apesoa nakong ea ts'ebeliso.
2. Qoba ho kopana le li-oxidizing tse matla ho qoba mollo kapa ho phatloha.
3. E lokela ho bolokoa sebakeng se omeletseng, se pholileng le se nang le moea o motle, hole le mollo le lisebelisoa tse tukang.
5. Qoba ho tsoakana le lik'hemik'hale tse ling 'me u ipolokele hole le bana le batho ba sa tsebeng ho sebetsa.
