Zambiri Zolozera

Kugwiritsa ntchito 2, 6-dichloro-4-iodopyridine angagwiritsidwe ntchito ngati organic synthesis intermediates ndi intermediates mankhwala, makamaka ntchito mu labotale kafukufuku ndi chitukuko ndondomeko ndi ndondomeko kupanga mankhwala.

 

Mawu Oyamba
2,6-dichloro-4-iodopyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:

Ubwino:
- Maonekedwe: 2,6-Dichloro-4-iodopyridine ndi ufa wa crystalline woyera mpaka chikasu.
- Yokhazikika kutentha, koma imakonda kuwala ndi chinyezi.
- Imakhala ndi kusungunuka kwazinthu zosungunulira, monga methanol ndi methylene chloride.
- Mipweya yapoizoni imatulutsidwa ikayaka.

Gwiritsani ntchito:
- 2,6-Dichloro-4-iodopyridine ndi yofunika organic wapakatikati kuti angagwiritsidwe ntchito synthesis wa mankhwala ena.

Njira:
- 2,6-Dichloro-4-iodopyridine nthawi zambiri amatengedwa ndi zomwe pyridine iodide ndi cuprous chloride mu zosungunulira zoyenera.
- Zomwe zimafunikira zimafunikira kugwiritsa ntchito mikhalidwe yoyenera ndi zothandizira, nthawi zambiri m'malo osadziwika.

Zambiri Zachitetezo:
- 2,6-Dichloro-4-iodopyridine ndi organic pawiri kuti ndi poizoni ndi zokwiyitsa.
- Valani zodzitetezera zoyenera, monga zovala zoteteza m'maso ndi magolovesi, mukamagwira ntchito ndikugwiritsa ntchito.
- Pewani kutulutsa mpweya, kukhudza khungu ndi maso, komanso kupewa kumeza.
- Pewani kukhudzana ndi zinthu monga ma okosijeni ndi ma asidi amphamvu.
- Werengani ndikutsatira malangizo oyendetsera chitetezo ndi njira zogwirira ntchito mosamala musanagwiritse ntchito. Mukagwiritsidwa ntchito m'malo a labotale, njira zoyenera zoyendetsera chitetezo ziyenera kuwonedwa.
