3-Bromo-2 6-dichloropyridine (CAS# 866755-20-6) Chiyambi
3-Bromo-2,6-dichloropyridine ndi organic pawiri ndi mankhwala formula C5H2BrCl2N. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
- 3-Bromo-2,6-dichloropyridine ndi yolimba yokhala ndi mawonekedwe oyera mpaka achikasu a crystalline.
-Kusungunuka kwake kumakhala pafupifupi 60-62 digiri Celsius, ndipo kuwira kwake kumakhala pafupifupi madigiri 240 Celsius.
- 3-Bromo-2,6-dichloropyridine ndi yosasungunuka m'madzi, koma imasungunuka mu zosungunulira za organic monga ethanol ndi dimethylformamide (DMF).
Gwiritsani ntchito:
- 3-Bromo-2,6-dichloropyridine ndi yofunika organic synthesis wapakatikati, ntchito kwambiri m'mafakitale mankhwala ophera tizilombo, mankhwala ndi mankhwala.
- Itha kugwiritsidwa ntchito ngati zopangira zopangira zinthu zina, monga mankhwala ophera tizilombo, mankhwala oletsa khansa ndi utoto wa fulorosenti.
Njira Yokonzekera:
Kukonzekera kwa -3-Bromo-2,6-dichloropyridine angapezeke pochita 2,6-dichloropyridine ndi bromine.
-Zomwe zimachitikira zimafunikira kutenthedwa ndipo zimachitika muzosungunulira zoyenera monga acetone kapena dimethylbenzamide.
Zambiri Zachitetezo:
- 3-Bromo-2,6-dichloropyridine iyenera kusungidwa mu mawonekedwe a fumbi ndikusungidwa pamalo ozizira, owuma, kutali ndi moto ndi kutentha kwakukulu.
-Valani zida zodzitetezera zoyenera monga magalasi, magolovesi ndi zovala zodzitetezera mukazigwiritsa ntchito.
-Pewani kukhudza khungu, maso ndi kupuma. Ngati mwakumana mwangozi, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupempha thandizo lachipatala.
-Pogwiritsa ntchito ndikusunga, samalani kuti muzitsatira njira zoyendetsera chitetezo kuti mutsimikizire chitetezo chaumwini ndi chitetezo cha chilengedwe.
