Folasaga

3,5-difluorophenylhydrazine hydrochloride o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i lona natura, fa'aoga, auala gaosi ma fa'amatalaga saogalemu:

 

Meatotino: E solu i le vai ma nisi so'o so'o e pei ole ethanol, methanol. Ose vaila'au vaivai vaivai e fa'afefe ma alkalis.

 

Fa'aaogā:

3,5-difluorophenylhydrazine hydrochloride e masani ona faʻaaogaina e fai ma sui faʻaitiitia ma faʻamalosi i le faʻaogaina o meaola. E mafai ona faʻaaogaina mo faʻaopoopoga faʻalavelave, faʻaitiitia mea faʻapitoa e pei o ketones, aldehydes, ketones aromatic, ma isi.

 

Metotia:

3,5-Difluorophenylhydrazine hydrochloride e mafai ona maua e ala ile tali ole hydroquinone ma le 2-chloro-1,3,5-trifluorobenzene. I se tulaga lautele, o le hydroquinone e tali atu i le sili atu o le 2-chloro-1,3,5-trifluorobenzene i lalo o tulaga alkaline e maua ai le 3,5-difluorophenylhydrazine. E ala i le tali atu i le hydrogen chloride, e mafai ona maua le 3,5-difluorophenylhydrazine hydrochloride.

 

Fa'amatalaga Saogalemu:

3,5-Difluorophenylhydrazine hydrochloride o se vailaʻau e masani ona faʻaaogaina i fale suʻesuʻe ma fale gaosi oloa. E tatau ona mulimulita'i tulafono talafeagai i le taimi o le fa'agasologa, ma e tatau ona ofuina ni mea e puipui ai le tagata lava ia e pei o totigilima, matatioata saogalemu, ma ofutino falesuesue. E itiiti le oona, ae e tatau lava ona aloese mai le faʻafesoʻotaʻi ma le paʻu, mata, ma le manava. I le tulaga o le faʻaalia, e tatau ona fufulu vave i le tele o vai ma saili vave togafitiga faafomaʻi. I le taimi o le teuina, e tatau ona taofia mai i puna o afi ma mea e mu, ma teu i se nofoaga matutu, lelei le faʻafefe.
