6-CHLORO-4-METHYLPYRIDIN-3-CARBOXALDEHYDE (2-CHLORO-5-FORMYL-4-PICOLINE) NDI COMPOUND WACHIWIRI. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:
Ubwino:
- Maonekedwe: 6-Chloro-4-methylpyridine-3-carboxaldehyde ndi madzi otumbululuka achikasu.
- Kusungunuka: Kutha kusungunuka muzinthu zambiri zosungunulira organic, monga ethanol, ether, ndi chloroform.
- Kukhazikika: Chigawochi chimakhala chokhazikika kutentha kwa chipinda, koma chimatha kuwola ndi kutentha, moto, kapena acidic kwambiri.
Gwiritsani ntchito:
- 6-chloro-4-methylpyridine-3-carboxaldehyde ndi yofunika kwambiri pakati pa kaphatikizidwe ka organic ndipo nthawi zambiri imagwiritsidwa ntchito popanga zinthu zina.
Njira:
- 6-Chloro-4-methylpyridine-3-carboxaldehyde nthawi zambiri amakonzedwa ndi kaphatikizidwe kakufanana ndi njira zotsatirazi:
1. 4-methylpyridine amathandizidwa ndi alkali kuti apeze ma ions osagwirizana nawo.
2. Ma ion opanda pake amachitidwa ndi cuprous chloride kupanga alkyl copper intermediates.
3. Alkyl copper intermediates imakhudzidwa ndi formaldehyde kupanga 6-chloro-4-methylpyridine-3-carboxaldehyde.
Zambiri Zachitetezo:
- 6-Chloro-4-methylpyridine-3-carboxaldehyde ikhoza kukhala yovulaza thupi la munthu, ndipo njira zotetezera zoyenera ziyenera kuchitidwa pogwiritsira ntchito, monga kuvala zipangizo zoyenera zotetezera (monga magolovesi, magalasi, ndi zovala zoteteza).
- Iyenera kusungidwa pamalo ozizira, owuma komanso mpweya wabwino, kutali ndi moto ndi okosijeni.
- Pewani kutulutsa mpweya, kukhudzana ndi khungu komanso kumeza mukamagwira ntchito ndikugwiritsa ntchito.
- Mukangokhudzana, tsukani malo okhudzidwa ndi madzi ambiri ndikupita kuchipatala.
