Selelekela
3,5-Difluoropyridine ke motsoako oa tlhaho o nang le motsoako oa lik'hemik'hale C5H3F2N. E latelang ke tlhaloso ea sebopeho sa eona, tšebeliso, tlhahiso le tlhaiso-leseling ea polokeho:
Tlhaho:
-Ponahalo: mokelikeli o se nang 'mala
- Sebaka se qhibilihang: -53 ℃
Sebaka se belang: 114-116 ℃
- Boima: 1.32g/cm³
-Solubility: E qhibiliha ka metsing le boholo ba lihlapolli tsa tlhaho.
Sebelisa:
- 3,5-Difluoropyridine e sebelisoa haholo-holo e le thepa ea bohlokoa e tala ho motsoako oa lintho tse phelang. E ka sebelisoa ha ho etsoa chefo e bolaeang likokoanyana, meriana le metsoako e meng ea manyolo.
-E ka boela ea sebelisoa e le reagent ea lik'hemik'hale bakeng sa tlhahlobo le lipatlisiso tsa lik'hemik'hale.
Mokhoa oa ho itokisa:
Tokisetso ea 3,5-Difluoropyridine hangata e etsoa ke e 'ngoe ea mekhoa e latelang:
-Ho qala ho pyrimidine, qala ka ho hlahisa liathomo tsa fluorine ho pyrimidine, ebe u eketsa liathomo tsa fluorine sebakeng sa 3 le 5.
-e fumanoang ho 3,5-difluoro chloropyrimidine kapa 3,5-difluoro bromopyrimidine reaction.
Lintlha tsa Tšireletseho:
- 3,5-Difluoropyridine e ka ba kotsi ho 'mele oa motho. Ho pepesetsoa motsoako ho ka baka ho teneha ha mahlo le letlalo. Ka hona, hoa hlokahala ho nka mehato e hlokahalang ea tšireletso, joalo ka ho roala liatlana tse loketseng, likhalase le liaparo tse sireletsang.
-Ha u tšoara kapa u hema 3,5-Difluoropyridine, sebaka se amehileng se lokela ho hloekisoa hang-hang 'me se eletsoa ke ngaka.
-Nakong ea ho boloka le ho sebetsana, tlhokomelo e lokela ho nkoa ho qoba ho kopana le li-oxidants tse matla le li-acids tse matla.
Ka kopo hlokomela hore ha u sebelisa le ho tšoara 3,5-Difluoropyridine, kamehla latela mekhoa e nepahetseng ea ts'ireletso ea laboratori 'me u bue ka maqephe le litaelo tsa polokeho tse amehang.
