Folasaga
3-Chloro-4-methylpyridine o se faʻalapotopotoga faʻapitoa. O ona meatotino e faapea:
1. Fa'aaliga:3-chloro-4-methylpyridineose vai e leai se lanu e samasama malamalama.
2. Malosi: 1.119 g/cm³
4. Solubility: 3-chloro-4-methylpyridine e soluble i le tele o solvents organic ma e le mafai ona solu ile vai.
O faʻaoga autu o le 3-chloro-4-methylpyridine e faʻapea:
1. Fa'amaopoopoina o fa'a'aumea fa'asolo: Ose mea fa'atauva'a taua e fa'aogaina i le kemisi fa'amaopoopo mo le tu'ufa'atasiga o le amino alcohols, amino alkates, ma isi fa'atosina heterocyclic nitrogen.
2. Vailaau fa'alafua fa'alafua: 3-chloro-4-methylpyridine e mafai ona fa'aaogaina e fai ma mea fa'avaitaimi i nisi o iniseti ma herbicides.
O le auala mo le saunia o le 3-chloro-4-methylpyridine e masani ona aofia ai laasaga nei:
1. Nitroation reaction of pyridine: pyridine e tali atu i le nitric acid concentrated ma le sulfuric acid e maua ai le 3-nitropyridine.
2. Fa'aitiitiga tali: 3-nitropyridine o loʻo faʻaalia ma le sili atu o le sulfoxide ma le faʻaitiitia o le mea e faʻaitiitia ai (e pei o le zinc powder) e maua ai le 3-aminopyridine.
3. Chlorination tali: 3-aminopyridine e tali atu i le thionyl chloride e maua ai le 3-chloro-4-methylpyridine.
O faʻamatalaga saogalemu talafeagai o le 3-chloro-4-methylpyridine e faʻapea:
1. Fa'alogona: E ono iai se fa'aa'ai i nisi o tagata.
2. Fa'aitaitagofie: E ono i ai se aafiaga fa'aita i mata, faiga fa'alenava ma le pa'u.
3. O'ona: E o'ona i le soifua maloloina o tagata ma e tatau ona mulimulita'i i faiga fa'agaioiga saogalemu.
4. Teuina: E tatau ona teuina i totonu o se atigipusa malulu, mamao ese mai le mumu ma oxidants, ma mamao mai le faʻafesoʻotaʻi ma le ea.
Pe a fa'aogaina le 3-chloro-4-methylpyridine, mulimuli i ta'iala talafeagai mo le saogalemu e pei o le ofuina o mata puipui, totigilima ma lavalava puipui, ma fa'amautinoa o lo'o fa'agaioia i se nofoaga e lelei le ea. I le tulaga o le fa'alavelave fa'afuase'i po'o le manava, saili vave togafitiga fa'afoma'i ma fa'aali le Pepa Fa'amatalaga o le Saogalemu o le oloa i lau foma'i.
