Folasaga
2-Chloro-6-methyl-5-nitropyridine o se faʻalapotopotoga masani masani,
Tulaga lelei:
- Fa'aaliga: 2-chloro-6-methyl-5-nitropyridine o se tioata e leai se lanu pe samasama.
- Solubility: E faigofie ona solu i solu fa'aola pei ole ethanol, dimethylformamide ma chloroform.
Fa'aaogā:
- Vai: O lenei tuufaatasiga e mafai ona faʻaaogaina e faʻapipiʻi ai nisi o vailaʻau faʻapisinisi, e pei o le fausaga o loʻo i ai le meatotino e faʻafefe ai le malamalama o le UV, ma e faʻaaogaina lautele i le pigmenti ma le vali.
Metotia:
2-Chloro-6-methyl-5-nitropyridine e mafai ona maua i le chlorination ma le nitrification o pyridine. O le auala faʻapitoa sauniuni e mafai ona faʻaaoga ai le nitric acid ma le sulfuric acid e tali atu ai e maua ai le nitrite acid, tali le nitrite ma le copper nitrate e fausia ai le kopa nitrate, ona faʻaaoga lea o le electrophilic methylation reagents (e pei o le methyl halogen) e tali atu ai i le kopa nitrate e maua ai le. oloa fa'atatau.
Fa'amatalaga Saogalemu:
2-Chloro-6-methyl-5-nitropyridine o se vailaʻau oona e faʻafefe ma matautia. Pe a fa'aoga ma tagofia, e mana'omia ni puipuiga talafeagai e pei o le ofuina o mata, totigilima ma lavalava puipui. Aloese mai le manavaina o ona ausa po o le pefu, ma aloese mai le paʻi i le paʻu ma mata. A fa'aogaina lenei mea, e tatau ona fa'aeteete i lona mautu ma 'alofia le fa'afeso'ota'i ma isi vaila'au e le fetaui. Pe a teu, e tatau ona teuina i totonu o se atigipusa malulu, mamao ese mai le mumu ma oxidants.
