Folasaga
2,3-dibromo-5-methylpyridine (2,3-dibromo-5-methylpyridine) o se faʻalapotopotoga faʻapitoa faʻatasi ma le vailaʻau vailaʻau C6H5Br2N. O lo'o taua i lalo se fa'amatalaga o lona natura, fa'aoga, sauniuniga ma fa'amatalaga saogalemu:
natura:
2,3-dibromo-5-methylpyridine o se lanu samasama ma se manogi manogi. O lo'o i ai le mea fa'afefete e tusa ma le 63-65 tikeri Celsius ma le mea e fa'apuna ai e tusa ma le 269-271 tikeri Celsius. E le mafai ona solu i le vai ma solu i solu vai.
Fa'aaogā:
2,3-dibromo-5-methylpyridine o se faʻaogaina faʻasolosolo faʻalagona. E mafai ona faʻaaogaina e faʻapipiʻi ai isi vailaʻau faʻalaʻau, e pei o mea e maua mai i mea ola olaola, vailaʻau ma vailaau faʻasaina. E mafai fo'i ona fa'aoga mo le tu'ufa'atasia o meafaitino o masini fa'aeletoroni e pei o diodes fa'amalama fa'aola (OLED) ma ma'a fa'aola.
Metotia:
2,3-dibromo-5-methylpyrridine e mafai ona maua e ala i le tali atu i le 5-methylpyridine ma le bromine. O le 5-Methylpyridine e muamua faʻatasi ma le hydrogen bromide, ona faʻaauau ai lea ona faʻafefe i le methyl chloride i le i ai o se faʻamalosi e maua ai le oloa faʻatatau.
Fa'amatalaga Saogalemu:
2,3-dibromo-5-methylpyrridine e faʻafefe ma e ono mafua ai le ita i mata, paʻu ma le manava. I le taimi o le faʻaaogaina, e tatau ona mataʻituina lelei le faʻaogaina o gaioiga, faʻafesoʻotaʻi tuusaʻo ma le paʻu ma mata e tatau ona aloese mai ai, ma e tatau ona faʻamautinoa le taʻaloga i se nofoaga lelei. I le taimi o le taulimaina ma le teuina, e tatau ona faʻaeteete e aloese mai le faʻafesoʻotaʻi ma vailaʻau faʻamaʻi ma mea e mu e puipuia ai le lamatiaga o le afi ma le pa. Afai e manavaina pe a'afia i lenei vaila'au, saili vave fautuaga fa'afoma'i ma fa'afeso'ota'i se foma'i fa'apitoa.
