Intshayelelo
I-2-chloro-5-fluoronicotinic acid. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-2-chloro-5-fluoronicotinic acid:
Umgangatho:
- I-2-Chloro-5-fluoronicotinic acid yikristale engenambala eqinileyo.
- Kwiqondo lobushushu begumbi, ine-solubility ephantsi kunye ne-solubility encinci emanzini.
- I-acidic kakhulu kwaye inokusabela nge-alkali ukuvelisa ityuwa ehambelanayo.
- I-2-Chloro-5-fluoronicotinic acid yinto ene-oxidizing kakhulu.
Sebenzisa:
- I-2-Chloro-5-fluoronicotinic acid ingasetyenziswa njenge-reagent ye-acids eqinile njenge-acid catalyst kwi-organic synthesis reactions.
- Ingasetyenziselwa ukuphendulwa kwefluorinated kwi-organic synthesis, efana ne-fluorination kunye ne-aromatics cyclofluorination.
- I-2-Chloro-5-fluoronicotinic acid ingasetyenziselwa njengento ephakathi kwidayi kunye nezikhanyisi ze-fluorescent.
Indlela:
- Indlela eqhelekileyo yokulungiselela i-2-chloro-5-fluoronicotinic acid ngokuphendula i-2,5-diaminoalkynyl niacin kunye nenani elifanelekileyo le-hydrofluoric acid kunye ne-chlorinating agents.
Ulwazi ngoKhuseleko:
- I-2-chloro-5-fluoronicotinic acid yi-organic compound ecasulayo kwaye ingaba nemiphumo ephazamisayo kwesikhumba, amehlo kunye nenkqubo yokuphefumula. Nxiba isixa esifanelekileyo sezixhobo zokukhusela xa usebenzisa kwaye uthintele ukudibana ngqo nolusu namehlo.
- Ngexesha lokusebenza, umoya kufuneka uqiniswe ukuze ugweme ukuphefumla umphunga ovela kule khompawundi.
- I-2-Chloro-5-fluoronicotinic acid kufuneka igcinwe kude nemithombo yobushushu kunye nezinto ezinokutsha kwaye igcinwe kwindawo eyomileyo, epholileyo.
