Mawu Oyamba
2,3,5-Tribromopyridine ndi organic pawiri ndi mankhwala chilinganizo C5H2Br3N. Zotsatirazi ndikuyambitsa zina mwazinthu zake, kagwiritsidwe ntchito, kapangidwe kake ndi zambiri zachitetezo:
Chilengedwe:
-Maonekedwe: 2,3,5-Tribromopyridine ndi yolimba yachikasu yopanda mtundu.
-Kusungunuka: Simasungunuka m'madzi, koma imatha kusungunuka muzosungunulira organic monga chloroform, dichloromethane, ndi zina.
-Posungunuka: 2,3,5-Tribromopyridine ili ndi malo osungunuka pafupifupi 112-114 ° C.
Gwiritsani ntchito:
- 2,3,5-Tribromopyridine nthawi zambiri amagwiritsidwa ntchito ngati reagent komanso wapakatikati mu kaphatikizidwe ka organic.
-Amagwiritsidwa ntchito kwambiri pakupanga mankhwala, kupanga mankhwala ophera tizilombo komanso kukonza utoto.
-Kuonjezera apo, itha kugwiritsidwanso ntchito ngati poyambira poyambira zitsulo zopangidwa ndi zitsulo (kuphatikizapo ma polima ogwirizanitsa ndi zipangizo za photoelectric).
Njira Yokonzekera:
Kukonzekera njira ya 2,3,5-Tribromopyridine chingapezeke mwa njira zotsatirazi:
Choyamba, pyridine imasungunuka mu zosungunulira organic monga dichloromethane kapena chloroform.
2. Onjezani bromine ku yankho ndikutenthetsa zomwe zimachitika.
3. Akamaliza anachita, mankhwala brominated anali hydrolyzed ndi dropwise Kuwonjezera madzi.
4. Pomaliza, mankhwalawa amadzipatula ndikuyeretsedwa ndi kusefera, crystallization, etc.
Zambiri Zachitetezo:
- 2,3,5-Tribromopyridine sichidzayambitsa nkhani zachitetezo pansi pazikhalidwe zogwirira ntchito.
-Zitha kuyambitsa kuyabwa pakhungu, maso ndi kupuma, choncho valani zida zoyenera zodzitetezera mukazigwiritsa ntchito.
-Yang'anani njira zoyenera za labotale ndi njira zodzitetezera pogwira ntchitoyi.
-Posunga ndi kusamalira pawiri, chisamaliro chiyenera kutengedwa kuti musagwirizane ndi ma oxidants, ma acid amphamvu, maziko amphamvu ndi zinthu zina.
Chonde dziwani kuti zomwe zili pamwambazi ndizongogwiritsa ntchito. Mukamagwiritsa ntchito 2,3,5-Tribromopyridine kapena mankhwala ena aliwonse, chonde tsatirani malangizo ogwiritsira ntchito moyenera ndikugwiritsa ntchito moyenera, ndipo werengani ndikutsatira chikalata chachitetezo chamankhwala oyenera.
