Mawu Oyamba
2-Chloro-3,5-dibromopyridine ndi organic pawiri ndi mankhwala formula C5H2Br2ClN. Zotsatirazi ndizofotokozera za chikhalidwe chake, kagwiritsidwe ntchito, kapangidwe ndi chitetezo:
Chilengedwe:
- 2-Chloro-3,5-dibromopyridine ndi makristasi olimba, opanda mtundu mpaka otumbululuka. Ili ndi malo osungunuka a 61-63 madigiri Celsius ndi malo otentha a 275-280 madigiri Celsius.
-Ili ndi mphamvu yosungunuka, yosungunuka m'madzi ambiri osungunulira, monga ethanol, dimethylformamide ndi dichloromethane.
Gwiritsani ntchito:
- 2-Chloro-3,5-dibromopyridine imagwiritsidwa ntchito kwambiri muzochita za organic synthesis ngati chinthu chapakatikati chofunikira. Ikhoza kugwiritsidwa ntchito popanga mankhwala atsopano, mankhwala ophera tizilombo ndi mankhwala ena achilengedwe.
-Itha kugwiritsidwanso ntchito ngati inhibitor yachitsulo ya corrosion and precursor for optical materials.
Njira Yokonzekera:
- 2-Chloro-3,5-dibromopyridine ikhoza kukonzedwa pochita 3,5-dibromopyridine ndi chlorinating agent. Mwachitsanzo, dibromopyridine imatha kupangidwa ndi chlorine pogwiritsa ntchito sulfoxide ndi chlorine pansi pamikhalidwe yoyenera kuti apereke mankhwalawo.
Zambiri Zachitetezo:
- 2-Chloro-3,5-dibromopyridine ndi mankhwala oopsa ndipo chisamaliro chiyenera kutengedwa kuti tipewe kupuma, kukhudzana ndi khungu ndi kuyamwa. Valani zida zodzitetezera zoyenera monga magolovesi, magalasi ndi masks mukamagwiritsa ntchito.
-Pogwira ndi kusunga 2-Chloro-3,5-dibromopyridine, tsatirani njira zoyenera zoyendetsera chitetezo ndikuonetsetsa kuti malo ogwirira ntchito ali ndi mpweya wabwino.
-Mukakhudzana mwangozi kapena pokoka mpweya, pitani kuchipatala msanga kutali ndi komwe munachokera.
