Folasaga
O le 4-Methyl-2-nitrophenol o se faʻalapotopotoga faʻapitoa faʻatasi ma le fua faʻasolosolo C7H7NO3. O lo'o taua i lalo se fa'amatalaga o lona natura, fa'aoga, sauniuniga ma fa'amatalaga saogalemu:
natura:
4-methyl -2-nitrophenol o se tioata paʻepaʻe, paʻepaʻe i le malamalama samasama, e iai se manogi manogi faʻapitoa i le vevela o le potu. E toetoe lava a le mafai ona solu i totonu o le vai, ae mafai ona solu i solu faʻaletino pei ole ethanol ma eter.
Fa'aaogā:
4-methyl -2-nitrophenol o loʻo faʻaaogaina lautele i le faʻaogaina o meaola. Talu ai ona e lua mea e suitulaga i ai, hydroxyl ma nitro, e mafai ona faʻaaogaina e fai ma sui o le antibacterial, faʻasao ma le peroxide stabilizer. E le gata i lea, o loʻo faʻaaogaina foi i le gaosiga o vali, pigments ma fluorescent dyes.
Sauniuniga auala:
4-methyl -2-nitrophenol e mafai ona faʻapipiʻiina e ala i le faʻafefeteina o toluene. Muamua, toluene ua fefiloi ma le sulfuric acid concentrated i le i ai o le nitric acid ma tali atu i se vevela talafeagai mo se vaitaimi patino e maua ai se oloa, lea e oo atu i laasaga mulimuli ane o crystallization, filtration ma mago e iu lava ina maua 4- methyl-2-nitrophenol.
Fa'amatalaga Saogalemu:
O le 4-Methyl-2-nitrophenol ose vailaʻau oona e faʻafefe ma pala. O le a'afia i ai e ono mafua ai le fa'aleagaina o le pa'u, fa'afefe mata ma le fa'afefe o le manava. O le mea lea, pe a faʻaaogaina pe faʻaaogaina, e tatau ona e ofuina ni mea puipui talafeagai, e pei o totigilima, mata tioata ma mea e puipuia ai le manava e aloese ai mai le faʻafesoʻotaʻi saʻo ma le manava. E le gata i lea, o se mea e mu ma e tatau ona taofia mai le afi ma le vevela. I le taimi o le teuina ma le felauaiga, e tatau ona faʻaeteete e aloese mai le faʻafefiloi ma vailaʻau faʻamaʻi ma mea faʻafefe. I lalo o togafitiga le talafeagai, e ono mafua ai le filogia ma afaina ai le siosiomaga. O le mea lea, e tatau ona mulimulita'i faiga talafeagai mo le saogalemu ina ia mautinoa le fa'aoga tatau ma le lafoaia o le fa'aputuga.
