Folasaga

2,6-dimethylpyridine o se faʻalapotopotoga faʻapitoa. O loʻo taua i lalo se faʻamatalaga i meatotino, faʻaoga, auala sauniuni ma faʻamatalaga saogalemu o le 2,6-dimethylpyridine:

 

Tulaga lelei:

2,6-Dimethylpyridine o se vai e leai ni lanu ma se manogi manogi malosi.

 

Fa'aaogā:

2,6-Dimethylpyridine o loʻo i ai le tele o faʻaoga:

1. E mafai ona faʻaaogaina e avea o se catalyst ma reagent i faʻasologa faʻasologa o meaola.

2. E faʻaaogaina e avea o se mea mataʻutia mo le saunia o vali, fluorescents ma mea faʻapitoa.

3. Faʻaaogaina e pei o solvent ma extractant, faʻaaogaina lautele i le tele o vailaʻau faʻamaʻi ma alamanuia vailaʻau.

 

Metotia:

2,6-Dimethylpyridine e masani ona gaosia e le tali a le acetophenone ma le ethyl methyl acetate.

 

Fa'amatalaga Saogalemu:

1. E i ai se manogi manogi ma e tatau ona aloese mai le umi o le faʻafesoʻotaʻi ma aloese mai le manavaina o kasa poʻo ausa.

2. O totigilima puipui talafeagai, mata tioata ma lavalava puipui e tatau ona ofuina i le taimi o le taotoga.

3. Aloese mai le fa'afeso'ota'i ma vaila'au malolosi ma vaila'au malolosi e 'alofia ai fa'alavelave mata'utia.

4. Pe a teuina, e tatau ona tapunia lelei le atigipusa, mamao ese mai le afi ma le maualuga o le siosiomaga vevela.
