I-2-BROMO-3-FORMYLPYRIDINE (CAS# 128071-75-0)

I-2-Bromo-3-pyridine carboxaldehyde i-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:

Umgangatho:
I-2-Bromo-3-pyridine formaldehyde lulwelo olungenambala ukuya kumthubi oluluthuthu olunevumba eliphawulwe yi-pyridine kunye ne-aldehyde. Inyibilika kwi-solvents ezininzi ze-organic kwiqondo lobushushu begumbi kwaye ayinyibiliki emanzini. Yikhompawundi ene-reactivity eyomeleleyo enokuthi ingene kwiintshukumo ezahlukeneyo zendalo phantsi kweemeko ezithile.

Sebenzisa:
I-2-Bromo-3-pyridine formaldehyde inoluhlu olubanzi lwezicelo kwi-organic synthesis. Inokuthatha inxaxheba kwiimpendulo ezithile ezifana ne-borate etherification reaction, ialdol condensation reaction, njl.

Indlela:
I-2-Bromo-3-pyridine formaldehyde inokulungiswa ngokuphendula i-3-pyridine formaldehyde kunye ne-hydrogen bromide. I-Hydrogen bromide iqala idlule kwibhotile yokuhlamba igesi kwisisombululo se-methanol se-3-pyridine formaldehyde, kwaye emva koko umxube wokuphendula ushushu. Emva kokuba impendulo igqityiwe, imveliso ekujoliswe kuyo ifunyenwe ngeendlela ezifana ne-steam distillation okanye i-extraction.

Ulwazi ngoKhuseleko:
I-2-Bromo-3-pyridine carboxaldehyde yi-organic compound efuna imilinganiselo efanelekileyo yokuphatha ekhuselekileyo xa isetyenziswa okanye iphathwa. Inokucaphukisa kwaye idle ulusu, amehlo, kunye nomgudu wokuphefumla. Xa usetyenziswa, qinisekisa ukungena komoya kakuhle kwaye unxibe izixhobo ezikhuselayo ezifana neeglavu zokukhusela, iiglasi, kunye nemaski. Kuphephe ukuphefumla, ukungeniswa, okanye ukudibana nolusu. Xa ugcina, kufuneka ugcinwe kude nezinto ezivuthayo kunye ne-oxidants kwaye ugcinwe kwindawo epholileyo neyomileyo.
