2-Chloro-3-bromo-4-methylpyridine (CAS# 55404-31-4)
Mawu Oyamba
Ndi organic pawiri ndi mankhwala formula wa C6H5BrClN ndi molecular kulemera kwa 192.48g/mol. Zotsatirazi ndizofotokozera za chikhalidwe chake, kagwiritsidwe ntchito, kapangidwe ndi chitetezo:
1. chilengedwe:
-Mawonekedwe: madzi opanda utoto mpaka owala achikasu kapena olimba;
-Kuwira mfundo: za 220-222 ℃ (by barometer);
-malo osungunuka: pafupifupi 33-35 ℃;
-Kukhala tcheru ndi kuwala, kupewa nthawi yaitali padzuwa;
-Kusungunuka mu zosungunulira za organic monga ethanol ndi dimethylformamide.
2. gwiritsani ntchito:
-Monga wapakatikati: angagwiritsidwe ntchito pokonzekera mankhwala ena, monga fluorine munali mankhwala kapena zotumphukira zina heterocyclic mankhwala;
-Kugwiritsidwa ntchito mu kaphatikizidwe ka organic: Itha kugwiritsidwa ntchito ngati reagent yofunika mu kaphatikizidwe ka organic kuyambitsa magulu ogwira ntchito monga ma atomu a halogen kapena magulu amino.
3. Njira yokonzekera:
- Nthawi zambiri imatha kukonzedwa ndi kuphatikiza kwa chlorination, bromination ndi methylation ya pyridine.
4. Zambiri Zachitetezo:
- ndi organic pawiri, zingakhale zoopsa;
- ayenera kukhala mogwirizana ndi ndondomeko chitetezo mankhwala ntchito, kupewa kukhudzana mwachindunji ndi khungu ndi maso;
- Payenera kukhala mpweya wabwino pakagwiritsidwe ntchito popewa kupuma mpweya wa nthunzi;
-Kutaya zinyalala, tsatirani malamulo a m'deralo.
