Folasaga
4-nitrobenzoylhydrazide o se faʻalapotopotoga faʻapitoa.
Tulaga lelei:
4-Nitrobenzoylhydrazide o se samasama i le moli tioata tioata e solu i chloroform, ethanol, ma solvents acidic, ma toetoe lava a le mafai ona solu i le vai. E mu ma pa ma e tatau ona taulimaina ma le faaeteete.
Fa'aaogā:
4-nitrobenzoylhydrazide o se vailaʻau faʻamaʻi e masani ona faʻaaogaina e avea o se mea faʻapipiʻi faʻapipiʻi, amination reagent ma cyanide reagent i le faʻaogaina o meaola.
Metotia:
O le auala sauniuni o le 4-nitrobenzoylhydrazide e masani ona faʻaaogaina le tali o le benzaldehyde ma le hydrogen ammonia, lea e faʻamalosia e maua ai le 4-nitrobenzaldehyde, ona maua ai lea o le 4-nitrobenzoylhydrazide e ala i le faʻaitiitia o le tali.
Fa'amatalaga Saogalemu:
4-Nitrobenzoylhydrazide e maualuga le lamatiaga o le pa ma e tatau ona faʻaeteete e aloese mai le faʻafesoʻotaʻi tuusaʻo ma le paʻu ma le manava. E tatau ona faia ni puipuiga talafeagai i le taimi o le taulimaina ma le teuina ina ia mautinoa le saogalemu. Malamalama lelei i faʻamatalaga saogalemu talafeagai aʻo leʻi faʻaaogaina: ma mulimuli i le auala saʻo o le taulimaina ma le faʻaaogaina.
