Nhanganyaya
3,5-Dibromo-2-fluoropyridine is organic compound ine kemikari formula C5H2Br2FN. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzira uye ruzivo rwekuchengetedza:
Zvakasikwa:
- 3,5-Dibromo-2-fluoropyridine isimbi yakasimba ine chitarisiko chichena checrystalline.
-Kunyungudika kwayo i74-76 ℃, uye nzvimbo yayo yekubikira i238-240 ℃.
-Haisi kunyungudika mumvura pane tembiricha yekamuri, asi inogona kunyungudika mune mamwe organic solvents senge ether uye ethanol.
Shandisa:
- 3,5-Dibromo-2-fluoropyridine chinhu chakakosha chepakati chepakati chinoshandiswa zvakanyanya mukugadzirwa kwe organic synthesis.
-Inogona kushandiswa seyakasvibirira yezvigadzirwa zve organic photovoltaic, uye inogona kushandiswawo kugadzira mishonga, dhayi uye mishonga yezvipembenene.
Kugadzirira nzira:
- 3,5-Dibromo-2-fluoropyridine inogona kugadzirirwa nekuita kwepyridine iodide uye cuprous bromide.
-Kutanga kunyungudutsa cuprous bromide uye pyridine iodide mu dimethyl sulfoxide pakamuri tembiricha kuti uite reactant, wobva wawedzera zvishoma nezvishoma sirivheri fluoride inodonha pakudzika kwakadzika, uye pakupedzisira kupisa kusvika mhinduro yapera.
Zvekuchengetedza
- 3,5-Dibromo-2-fluoropyridine inotsamwisa ganda nemaziso, uye matanho ekudzivirira anofanira kubhadharwa paanenge asangana.
-Cherechedza kufefetera kwakanaka kana uchishandisa komboni iyi.
-Iyo inoora pakupisa kwepamusoro inoburitsa magasi anokuvadza, uye zvinodikanwa kuti udzivise kuratidzwa nemirazvo yakazaruka kana nharaunda dzekushisa.
-Chengetedza nenzira yakavharwa uye dzivisa kusangana neoxidants uye yakasimba acids kuti udzivise kuita zvine njodzi.
