Isingeniso:

I-5-Formylpyridine-2-formitrile, eyaziwa nangokuthi i-2-Pyridinecarbonitrile, 5-formyl-(9CI), iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:

Ikhwalithi:
- Ukubukeka: Amakristalu angenambala
- Ukunyibilika: kuncibilika kancane emanzini, kuncibilika kuzincibilikisi zemvelo ezifana notshwala nama-ether

Sebenzisa:

Indlela:
- Indlela yokulungiselela ye-5-formylpyridine-2-formonitrile ngokuvamile ihilela ukusabela kwe-pyridin-2-carboxylic acid ne-sodium cyanide, bese kwenziwa ukusabela kwe-acylation ukuze kutholwe umkhiqizo ohlosiwe.

Ulwazi Lokuphepha:
- I-5-Formylpyridine-2-formonitrile ingase icasule amehlo nesikhumba, ukuthintana nesikhumba namehlo kufanele kugwenywe, futhi amagilavu okuzivikela kanye nezibuko kufanele kugqokwe uma kunesidingo.
- Ukuhogela uthuli noma amagesi avela kulesi sakhi kufanele kugwenywe ngesikhathi sokusebenza ukuze kugwenywe ukucasuka emgudwini wokuphefumula.
- Imithetho yokuphatha ephephile yamakhemikhali kufanele ilandelwe ngesikhathi sokugcinwa nokuphathwa, futhi kuqinisekiswe izimo ezinhle zokungenisa umoya.

Okwedlule: I-5-Chloro-2 4-difluorobenzoic acid (CAS# 130025-33-1)

Olandelayo: 3 4-DIBROMOPYRIDINE (CAS# 13534-90-2)
