Sebaka se belang: hoo e ka bang 290-305 ° C
-Botebo: Hoo e ka bang 1.64 g/mL
- Boima ba molek'hule: 174.01g / mol
Sebelisa:
5-bromo-3-cyanopyridine e atisa ho sebelisoa e le karolo e bohareng ea motsoako oa manyolo, 'me e na le litšebeliso tsa bohlokoa masimong a motsoako oa lithethefatsi, motsoako oa chefo e bolaeang likokoanyana le motsoako oa dae.
Lisebelisoa tse khethehileng li kenyelletsa:
- Lefapheng la meriana, e ka sebelisoa ho kopanya lithethefatsi tse khahlanong le hlahala, lithethefatsi tse thibelang likokoana-hloko le lithethefatsi tse thibelang likokoana-hloko.
- Lefapheng la chefo e bolaeang likokoanyana, e ka sebelisoa bakeng sa chefo e bolaeang likokoanyana le litlama.
-Lebaleng la lidae, e ka sebelisoa ho kopanya lidae tsa manyolo.
Mokhoa oa ho itokisa:
Mokhoa oa ho lokisetsa 5-bromo-3-cyanopyridine o ka etsoa ka mehato e latelang:
1. 3-cyanopyridine e sebetsana le hydrobromic acid tlas'a maemo a alkaline ho hlahisa 5-bromo-3-cyanopyridine.
Lintlha tsa Tšireletseho:
Mehato e latelang ea tšireletso e lokela ho nkoa ha u sebelisa 5-bromo-3-cyanopyridine:
-Ke motsoako oa manyolo o halefisang. Qoba ho hema lerōle kapa ho kopana le letlalo le mahlo.
-Ho sebelisoa le ho boloka, ho lokela ho latela mekhoa ea ts'ireletso, ho roala lisebelisoa tsa ho itšireletsa, tse kang li-gloves le likhalase tsa tšireletso.
- Qoba ho kopanya kapa ho kopana le lintho tse kang li-oxidants tse matla le li-acid tse matla ho thibela liketso tse kotsi.
- Boloka sebakeng se nang le moea o kenang hole le malakabe a bulehileng le mehloli ea mocheso.
-Haeba o hema kapa o kopane le letlalo le mahlo, hlatsoa hang-hang ka metsi. Batla thuso ea lingaka haeba ho hlokahala.
Ka lebaka la litaba tsa ts'ireletso, tšebeliso le ts'ebetso ea 5-bromo-3-cyanopyridine e lokela ho latela mekhoa e nepahetseng ea laboratori le ho latela melao e nepahetseng ea tšireletso.
