Intshayelelo
I-organic compound kunye ne-molecular formula C6H4FN, eguqulwa ngokwesakhiwo liqela le-5-formaldehyde kwindandatho ye-2-fluoropyridine. Oku kulandelayo yinkcazo eneenkcukacha yezakhiwo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko lwekhompawundi:
Indalo:
-Imbonakalo: Ulwelo olungenambala okanye olumthubi olukhanyayo.
-I-Solubility: Inyibilika kwizinto ezininzi ze-organic solvents, ezifana ne-ethanol, i-acetone, njl.
-Indawo yokunyibilika: malunga ne -5°C.
-Indawo yokubilisa: malunga ne-135 ℃.
-Ubunzima obuthile: malunga ne-1.214g/cm³.
Umxholo: Ubunyulu buhlala bungaphezulu kwama-95%.
Sebenzisa:
-iluncedo njengento yokuqala okanye ephakathi kwi-organic synthesis.
-Isetyenziswa ngokuqhelekileyo kwintsimi yamachiza ukulungiselela iziyobisi, ezifana ne-antipsychotics kunye neziyobisi ze-antineoplastic.
-Ikhompawundi ingasetyenziselwa ukulungisa i-pesticides, i-sensitizers, idayi, njl.
Indlela yokulungiselela:
Kukho iindlela ezimbini eziphambili zokulungiselela:
1. I-pyridine kunye ne-cyanide iodine reaction, kwaye emva koko i-fluorination reaction, kwaye ekugqibeleni yongeza imveliso ye-formaldehyde.
2. I-pyridine isabela nge-methane kunye ne-boron trifluoride ukwenza i-2-methylpyridine, emva koko i-fluorination reaction iqhutywe, kwaye i-formaldehyde yongezwa ukufumana i-pyridine.
Ulwazi ngoKhuseleko:
-Iqondo elithile lokucaphuka kunye nokubola, kufuneka ugweme ukudibanisa nolusu, amehlo kunye nomgudu wokuphefumula.
-Landela iinkqubo ezifanelekileyo zokhuseleko ngexesha lokusetyenziswa kunye nokugcinwa.
-Sebenzisa kwindawo engena umoya kwaye unxibe izixhobo ezifanelekileyo zokukhusela, ezinjengeeglavu, izibuko kunye nempahla yokukhusela.
-Xa udibana, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune unyango.
-Ulwelo kunye nenkunkuma kufuneka ilahlwe ngokuhambelana nemimiselo yendawo.
