Folasaga
3,5-Difluorobenzonitrile o se faʻalapotopotoga faʻapitoa. O loʻo taua i lalo se faʻamatalaga i nisi o meatotino, faʻaoga, auala sauniuni ma faʻamatalaga saogalemu o le 3,5-difluorobenzonitrile:
Tulaga lelei:
- Faʻaaliga: 3,5-Difluorobenzonitrile o se lanu e leai se lanu samasama samasama.
- Solubility: Solu i le tele o solu fa'aola pei ole ethanol, eter, ma chloroform.
Fa'aaogā:
- 3,5-Difluorobenzonitrile e masani ona faʻaaogaina e avea o se vaeluagalemu i le faʻaogaina o meaola.
- E mafai foʻi ona faʻaaogaina e avea o se vailaʻau faʻapitoa i totonu o le eletise eletise mo le gaosiga o vali ma mea faʻapipiʻi.
Metotia:
- O le auala autu o sauniuniga o le 3,5-difluorobenzonitrile e maua i le tali atu o le 3,5-difluorophenyl bromide ma le copper cyanide i lalo o tulaga talafeagai.
Fa'amatalaga Saogalemu:
- 3,5-Difluorobenzonitrile e faʻafefe ma faʻaleagaina, ma e tatau ona faʻaogaina faiga saogalemu e pei o le ofuina o totigilima puipui ma mata tioata i le taimi o le faʻaaogaina.
- Aloese mai le fa'afeso'ota'i sa'o ma le pa'u ma le manavaina o ona ausa, ma fa'agaioi i se nofoaga e fa'alelei lelei.
- Pe a taulimaina ma teuina le 3,5-difluorobenzonitrile, e tatau ona faʻaeteete e aloese mai le faʻafesoʻotaʻi ma oxidants, malosi malosi ma isi mea e puipuia ai le tupu mai o faʻalavelave mataʻutia.
- Va'ai i tusitusiga talafeagai mo le saogalemu ma le fa'aogaina o ta'iala pe a fa'aogaina pe fa'aaogaina lenei fa'aputuga, ma mulimulita'i tulafono talafeagai.
