Intshayelelo
I-6-Chloronicotinaldehyde (eyaziwa nangokuthi i-2,4,6-chlorobenzoic acid aldehyde) i-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-6-chloronicotinaldehyde:
Iipropati: I-6-Chloronicotinaldehyde yikristale engenambala okanye i-crystalline powder emhlophe enevumba elimnandi. Inokuchasana okuphakathi kwaye inokunyibilika kwizinto ezininzi ze-organic solvents ezifana ne-alcohols, i-ethers, kunye neetoni. Iphantse yanganyibiliki emanzini kodwa inokunyibilika kwizinyibilikisi zendalo.
Ukusetyenziswa: I-6-Chloronicotinaldehyde isetyenziswa rhoqo njenge-reagent kwaye iphakathi kwi-organic synthesis. Isetyenziswa njengento ekrwada kwizitshabalalisi, imichiza yokutshabalalisa ukhula, nemichiza yokungunda kwicandelo lezolimo.
Indlela yokulungiselela: I-6-chloronicotinaldehyde inokufumaneka ngokusabela kwe-benzoyl chloride kunye ne-aluminium chloride. Iimeko zokusabela zingenziwa kwiqondo lokushisa. Indlela ethile yokudibanisa imi ngolu hlobo lulandelayo:
C6H5COCl + AlCl3 -> C6H4ClCOCl + HCl
C6H4ClCOCl + HCl -> C7H3Cl3O + CO2 + HCl
Ulwazi lokhuseleko: I-6-Chloronicotinaldehyde iyacaphukisa, thintela ukudibanisa nolusu kunye namehlo. Kufuneka kuthatyathwe amanyathelo afanelekileyo okuzikhusela xa usebenzisa, njengokunxiba iiglavu, iimpahla zamehlo ezikhuselayo, neemaski zokuzikhusela. Kuphephe ukuphefumlela umphunga okanye uthuli lwalo ngexesha lokusebenza. Xa ugcina kwaye uphatha i-6-chloronicotinal, landela iinkqubo ezifanelekileyo zokusebenza ezikhuselekileyo kwaye uzigcine ngokukhuselekileyo kwisitya esichongiweyo. Xa ulahla inkunkuma, kufuneka ichithwe ngokufanelekileyo ngokuhambelana nemimiselo yendawo.
