Folasaga
2-Bromo-5-chloropyridine o se faʻalapotopotoga faʻapitoa, o loʻo taua i lalo o se folasaga i nisi o meatotino, faʻaoga, auala sauniuni ma faʻamatalaga saogalemu o le 2-bromo-5-chloropyridine:
Tulaga lelei:
1. Fa'aaliga: 2-bromo-5-chloropyridine o se lanu e leai se lanu i samasama lanu samasama.
3. Solubility: 2-bromo-5-chloropyridine o loʻo i ai le solubility lelei i solu faʻalaʻau masani, e pei o le ethanol, acetone ma le dimethyl thionite ether.
Fa'aaogā:
1. Reagents vailaʻau: 2-bromo-5-chloropyridine e masani ona faʻaaogaina e avea o se mea faʻapipiʻi i le faʻaogaina o meaola.
2. Pesticide intermediates: E faʻaaogaina foi i le tuʻufaʻatasia o vailaʻau faʻasaina e fai ma meamata mo iniseti poʻo vailaʻau.
Metotia:
Ole sauniuniga ole 2-bromo-5-chloropyridine e mafai ona maua ile tali ole 2-chloropyridine ile hydrobromic acid. O laʻasaga faʻapitoa e aofia ai le faʻamavaeina o le 2-chloropyridine i le cyclohexane anhydrous, faʻaopoopoina o le hydrobromic acid, faʻamafanafanaina o le tali ma le faʻaosoina, pe a maeʻa le tali, o le mea e maua ai le vaega o loʻo tuʻueseese i le vai ma le faʻamalieina o le sodium chloride solution, ma o le oloa faʻatatau e faʻamagoina. togafitiga ma fa'amama.
Fa'amatalaga Saogalemu:
1. 2-Bromo-5-chloropyridine o lo'o iai ni a'afiaga o le tino ma o'ona i le tino, ma e tatau ona fa'aeteete i le taimi e fa'aoga ai.
2. Aloese mai le pipii atu i le pa'u ma mata.
3. Pe a faʻaaogaina ma teuina, e tatau ona puipuia mai le afi ma le vevela.
4. E tatau ona tausisia tulaga lelei o le ea i le taimi o le taotoga.
5. Fa'amolemole mulimuli lelei i ta'iala talafeagai mo le saogalemu ma fa'aoga mea faigaluega puipui.
