Mawu Oyamba
4-Bromo-3,5-dichloropyridine ndi organic pawiri ndi mankhwala formula C5H2BrCl2N. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
4-Bromo-3,5-dichloropyridine ndi kristalo wopanda mtundu kapena wotumbululuka wachikasu wokhala ndi fungo lapadera lonunkhira. Malo ake osungunuka ndi pakati pa 80-82 ° C ndipo kuwira kwake kuli pakati pa 289-290 ° C. Izo sizisungunuka m'madzi pa kutentha kwabwino, koma zimasungunuka mu zosungunulira za organic monga ethanol ndi chloroform.
Gwiritsani ntchito:
4-Bromo-3,5-dichloropyridine imagwiritsidwa ntchito kwambiri pamakampani opanga mankhwala. Ndiwofunikira wapakatikati wa mankhwala a pyridine ndipo angagwiritsidwe ntchito popanga ma organic mankhwala ndi mankhwala. Ili ndi kukhazikika kwamankhwala abwino komanso reactivity, ndipo ingagwiritsidwe ntchito ngati chothandizira, ligand, utoto ndi zida zopangira mankhwala.
Njira Yokonzekera:
Kukonzekera njira ya 4-Bromo-3,5-dichloropyridine zambiri zimatheka ndi m'malo anachita pyridine. Njira yokonzekera yomwe imagwiritsidwa ntchito nthawi zambiri imaphatikizapo zomwe pyridine ndi bromine ndi ferric chloride, ndipo m'malo mwake zimachitikira pamikhalidwe yoyenera kuti mupeze zomwe mukufuna. Njira yokonzekera iyenera kuwongolera kutentha, mtengo wa pH ndi nthawi yochitira ndi magawo ena kuti mupeze zinthu zoyera kwambiri.
Zambiri Zachitetezo:
4-Bromo-3,5-dichloropyridine ndi gawo lokhazikika komanso lotetezeka nthawi zambiri, komabe ndikofunikira kulabadira ntchito yotetezeka. Itha kulowa m'thupi kudzera mu inhalation, kukhudza khungu ndi kuyamwa. Kukoka mpweya wambiri ndi fumbi kungayambitse kupsa mtima, kumayambitsa kupuma komanso kusapeza bwino kwa maso. Kukhudzana ndi khungu kungayambitse redness, kumva kulasalasa ndi thupi lawo siligwirizana. Kulowetsedwa kwa pawiri kungayambitse kupweteka kwa m'mimba ndi zotsatira za poizoni. Chifukwa chake, zida zoyenera zodzitetezera ziyenera kuvala mukamagwiritsa ntchito kuti musakumane mwachindunji komanso pokoka mpweya. Pakachitika ngozi, chithandizo chadzidzidzi chiyenera kuchitika munthawi yake ndipo akatswiri akuyenera kufunsidwa. Kuphatikiza apo, ziyenera kusungidwa pamalo owuma, opanda mpweya wabwino, kutali ndi moto ndi oxidizing agents.
