Folasaga

hydrochloride ose fa'aputu fa'aola fa'atasi ma le fua fa'a-kemikolo C7H9FN2 · HCl. O lo'o taua i lalo se fa'amatalaga o meatotino, fa'aoga, tapenaga ma fa'amatalaga saogalemu o le fa'aputuga:

natura:

-Fa'aaliga: Pa'epa'e tioata pa'epa'e

- Liu liusuavai: tusa o le 170-174 ° C

-Solubility: Solu i le vai ma solu fa'alafua lautele

Fa'aaogā:

-hydrochloride e mafai ona faʻaaogaina e avea o se vaeluaga taua ma reagent i le faʻagasologa o vailaʻau.

-E mafai ona faʻaaogaina e faʻapipiʻi ai amines aromatic fluorinated ma isi mea faʻapipiʻi.

Metotia:

O le fa'aogaina o le hydrochloride e masani lava ona maua e ala i le fa'afo'iina o le 5-Fluoro-2-methylphenylhydrazine ma le hydrogen chloride i toluene.

-Muamua, vevela ma faʻamavae le 5-fluoro-2-methylphenylhydrazine i toluene, ona faʻasolosolo malie lea o le hydrogen chloride gas, ma faʻaauau le tali mo ni nai itula.

-Fili le malo, faʻafefiloi lona hypoacetate ma le n-heptane ma malulu e maua ai tioata o le hydrochloride.

-Mulimuli, e maua le oloa mama e ala i laasaga o filtration, mago ma recrystallization.

Fa'amatalaga Saogalemu:

-O le hydrochloride e tatau ona gauai atu i le saogalemu i le taimi o le taotoga.

-O se faʻalapotopotoga faʻaola ma nisi oona ma ita. E tatau ona 'alofia le fa'afeso'ota'i sa'o ma le pa'u ma le manava.

- Fa'aaoga mea e puipui ai, e pei o totigilima, mata tioata ma matapulepule, pe a fa'aoga.

-Taumafai e fa'agaoioi i se nofoaga e fa'alelei lelei ma aloese mai le pefu i le ea.

-O otaota e tatau ona faʻatinoina e tusa ai ma tulafono faʻalotoifale, aua le lafoaia pe faʻafefiloi isi vailaʻau.
