Isingeniso
I-6-Chloronicotinaldehyde (eyaziwa nangokuthi i-2,4,6-chlorobenzoic acid aldehyde) iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-6-chloronicotinaldehyde:
Izakhiwo: I-6-Chloronicotinaldehyde iyikristalu engenambala noma i-crystalline powder emhlophe enephunga elimnandi. Inokuphikisana okusesilinganisweni futhi ingancibilika kuzincibilikisi eziningi eziphilayo ezifana notshwala, ama-ether, nama-ketone. Cishe ayincibiliki emanzini kodwa ingancibilika kuzincibilikisi zemvelo.
Ukusetshenziswa: I-6-Chloronicotinaldehyde ivame ukusetshenziswa njenge-reagent futhi iphakathi ku-organic synthesis. Isetshenziswa njengezinto ezingavuthiwe zezibulala-zinambuzane, izibulala-khula, nezibulala-sikhunta emkhakheni wezolimo.
Indlela yokulungiselela: I-6-chloronicotinaldehyde ingatholwa ngokusabela kwe-benzoyl chloride ne-aluminium chloride. Izimo zokusabela zingenziwa ekamelweni lokushisa. Indlela ethize yokuhlanganisa imi kanje:
C6H5COCl + AlCl3 -> C6H4ClCOCl + HCl
C6H4ClCOCl + HCl -> C7H3Cl3O + CO2 + HCl
Ulwazi lokuphepha: I-6-Chloronicotinaldehyde iyacasula, gwema ukuthintana nesikhumba namehlo. Kufanele kuthathwe izinyathelo zokuzivikela ezifanele uma usebenzisa, njengokugqoka amagilavu, izingubo zamehlo ezivikelayo, nezifihla-buso zokuzivikela. Gwema ukuhogela umhwamuko noma uthuli lwawo ngesikhathi sokusebenza. Lapho ugcina futhi uphatha i-6-chloronicotinal, landela izinqubo ezifanele zokusebenza eziphephile futhi uyigcine iphephile esitsheni esimisiwe. Lapho kulahlwa imfucuza, kufanele ilahlwe ngendlela efanele ngokuhambisana nemithetho yendawo.
