Folasaga
2,5-Difluorobenzonitrile o se faʻalapotopotoga faʻapitoa. O loʻo taua i lalo se faʻamatalaga i nisi o meatotino, faʻaoga, metotia sauniuni ma faʻamatalaga saogalemu o le 2,5-difluorobenzonitrile:
Tulaga lelei:
- 2,5-Difluorobenzonitrile o se tioata lanu samasama lanu samasama ma se manogi manogi.
- 2,5-difluorobenzonitrile e toetoe lava a le mafai ona solu i le vai i le vevela o le potu, ae soluble i solvents organic pei ole ethanol, acetone, ma isi.
- O se fa'afefiloi ma se manogi manogi malosi.
Fa'aaogā:
- 2,5-Difluorobenzonitrile o loʻo faʻaaogaina lautele i le faʻaogaina o meaola e avea o se vailaʻau vailaʻau mo le sauniuniga o isi mea faʻapipiʻi.
- E masani ona faʻaaogaina i le fluorination reactions ma aromatization reactions ona o le faʻaofiina o atoms fluorine e mafai ona suia ai meatotino o faʻalapotopotoga, faʻateleina lo latou hydrophobicity ma le mautu vailaʻau.
Metotia:
- 2,5-difluorobenzonitrile e mafai ona saunia e ala i le faʻaogaina o mea manogi. O se metotia masani o sauniuniga o le tali atu lea i le para-dinitrobenzene ma nitrosamines faʻapipiʻiina e le cuprous chloride ma le hydrofluoric acid e maua ai le 2,5-difluorobenzonitrile.
Fa'amatalaga Saogalemu:
- Pe a tagofia le 2,5-difluorobenzonitrile, fai mea e puipuia ai e pei o totigilima, mata tioata, ma se ofu suʻesuʻe.
- Ose mea fa'aitaita'i e ono fa'aita ai mata, pa'u, ma le manava.
- O le manavaina o ana ausa po'o le pefu, pa'u ma mata e tatau ona 'alofia i le taimi o le tagofiaina.
- E tatau ona gauai atu i faiga puipuia o afi ma pa i le taimi o le teuina ma le faʻaaogaina, ma ia aloese mai faʻapogai afi ma mea faʻamaʻi.
