Mawu Oyamba
3-Pyridine formaldehyde. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 3-pyridine formaldehyde:
Ubwino:
- Maonekedwe: 3-pyridine formaldehyde ndi madzi opanda mtundu kapena kristalo woyera.
- Kusungunuka: Imasungunuka mu zosungunulira zambiri monga ethanol ndi chloroform.
Gwiritsani ntchito:
- Kuphatikizika kogwiritsa ntchito: 3-pyridine formaldehyde nthawi zambiri imagwiritsidwa ntchito ngati chophatikizira, chapakatikati mu kaphatikizidwe ka organic ndi zopangira.
Njira:
- 3-Pyridine formaldehyde ikhoza kukonzedwa ndi N-oxidation ya pyridine. Njira yophatikizira yomwe imagwiritsidwa ntchito nthawi zambiri ndikuchita pyridine ndi oxidizing agent monga benzoyl peroxide kapena hydrogen peroxide kuti apange 3-pyridine formaldehyde.
Zambiri Zachitetezo:
- Njira zotsatirazi zodzitetezera ziyenera kuganiziridwa mukamagwiritsa ntchito ndikusunga 3-pyridine formaldehyde:
- Pewani kukhudzana ndi khungu ndipo pewani kutulutsa mpweya kapena kumeza mankhwalawo.
- Valani magolovesi oteteza mankhwala ndi zoteteza maso mukamagwiritsa ntchito.
- Gwiritsani ntchito pamalo olowera mpweya wabwino ndikupewa moto kapena kutentha kwambiri.
- Posunga, iyenera kukhala yosindikizidwa mwamphamvu, kutali ndi magwero amoto ndi zinthu zomwe zimatha kuyaka.
- Mukamagwiritsa ntchito 3-pyridine formaldehyde, tsatirani njira zoyendetsera chitetezo ndi njira zodzitetezera.
