Intshayelelo
I-3,5-Dibromo-2-fluoropyridine i-organic compound kunye ne-chemical formula C5H2Br2FN. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukuqulunqwa kunye nolwazi lokhuseleko:
Indalo:
- I-3,5-Dibromo-2-fluoropyridine i-compound eqinile kunye nembonakalo emhlophe ye-crystalline.
-Indawo yokunyibilika kwayo yi-74-76 ℃, kwaye indawo yayo yokubilisa yi-238-240 ℃.
-Ayinyibiliki emanzini kwiqondo lokushisa, kodwa inokunyibilika kwezinye i-solvents eziphilayo ezifana ne-ether kunye ne-ethanol.
Sebenzisa:
- I-3,5-Dibromo-2-fluoropyridine yinto ebalulekileyo ephakathi esetyenziswa ngokubanzi kwiimpendulo ze-organic synthesis.
-Ingasetyenziselwa njengento ekrwada yezinto eziphilayo ze-photovoltaic, kwaye ingasetyenziselwa ukulungiselela amayeza, idayi kunye nezibulala-zinambuzane.
Indlela yokulungiselela:
- I-3,5-Dibromo-2-fluoropyridine inokulungiswa ngokusabela kwe-pyridine iodide kunye ne-cuprous bromide.
-Qala unyibilikise i-cuprous bromide kunye ne-pyridine iodide kwi-dimethyl sulfoxide kwiqondo lobushushu begumbi ukwenza i-reactant, emva koko wongeze isilivere yefluoride dropwise kwiqondo lobushushu eliphantsi, kwaye ekugqibeleni shushu de ukusabela kugqitywe.
Ulwazi ngoKhuseleko:
- I-3,5-Dibromo-2-fluoropyridine iyacaphukisa ulusu kunye namehlo, kwaye amanyathelo okukhusela kufuneka ahlawulwe ingqalelo xa udibana.
-Nika ingqalelo ekungeneni komoya kakuhle xa usebenzisa le khompawundi.
-Ukubola kwiqondo lokushisa eliphezulu kuya kuvelisa iigesi ezinobungozi, kwaye kuyimfuneko ukuphepha ukuvezwa kwamadangatye avulekileyo okanye iindawo eziphezulu zokushisa.
-Yigcine ngendlela etywiniweyo kwaye ugweme ukudibanisa ne-oxidants kunye ne-acids eqinile ukuphepha ukuphendula okuyingozi.
