3,5-difluorobenzaldehyde ke motsoako oa tlhaho o nang le foromo ea lik'hemik'hale C7H4F2O. E latelang ke tlhaloso ea thepa, tšebeliso, tokiso le tlhaiso-leseling ea polokeho ea komporo:
Properties: 3,5-difluorobenzaldehyde ke 'mala o mosehla o mosehla o tiileng o nang le monko o khethehileng oa phenone. E na le boima ba 1.383g/cm³, ntlha e qhibilihang ke 48-52°C, le ntlha e belang ea 176-177°C. 3,5-difluorobenzaldehyde ha e qhibilihe ka metsing, empa e qhibiliha ka har'a metsoako ea tlhaho e kang ethanol, ether, le benzene.
Tšebeliso: 3,5-difluorobenzaldehyde hangata e sebelisoa e le karolo e bohareng ea organic synthesis. E ka sebelisoa ho kopanya metsoako e fapaneng e nang le fluorine, haholo bakeng sa karabelo ea lik'hemik'hale e hlahisang liathomo tsa fluorine ho limolek'hule tsa manyolo. Ho phaella moo, e ka boela ea sebelisoa e le setsi sa maiketsetso sa lithethefatsi, chefo e bolaeang likokoanyana le dae.
mokhoa oa ho itokisa: mokhoa oa ho lokisetsa 3,5-difluorobenzaldehyde o ka fumanoa ka ho itšoara ka 3,5-difluorobenzyl methanol e nang le acid aldehyde reagent (e kang trichloroformic acid, joalo-joalo). Mekhoa e khethehileng ea maiketsetso e ka lebisa ho Organic Synthesis Handbook le lingoliloeng tse amanang le tsona.
Lintlha tsa polokeho: 3,5-difluorobenzaldehyde ke k'hemik'hale 'me e hloka ho sebelisoa ka mokhoa o sireletsehileng. E ea teneha ebile ea senya 'me e ka baka tšenyo mahlong, letlalo le tsamaiso ea ho hema. Lisebelisoa tse nepahetseng tsa ts'ireletso tse kang likhalase, liatlana le lithebe tsa sefahleho li lokela ho apesoa nakong ea ts'ebeliso. Latela mekhoa ea ts'ireletso ea laboratori 'me u boloke, tšoara le ho lahla motsoako ka nepo. Haeba ho ka etsahala hore motho a kopane kapa a jeoa ka phoso, batla thuso ea bongaka hang-hang 'me u fane ka boitsebiso bo hlokahalang ho ngaka.
