Kako naj vam ljudje pomagajo, če niste omenili ničesar o uporabljenih reagentih in o tem, kaj ste delali
Preverite reagente

Koliko kisline in etanola ste dodali?
Koliko vode ste dodali?
Ko vam naslednjič nihče ne bo odgovoril, sem vam rekel, da podrobno omenite sintezo, da boste vedeli, kaj je narobe s tem

V nevtralizacijskem delu sem dodal približno 70, 80 ali 100 ml vode, nato sem dodal 50 ml destilirane vode, tj. 200 ml etanola, 100 ml žveplove kisline za kristalizacijo.

Če so reagenti pravilni, morajo obstajati kristali soli
Prepričajte se o tem

Pošljite sliko uporabljenih reagentov
Prepričajte se, da ste dodali natrijev karbonat

Prepričajte se, da se je zaradi vročine morda razgradil. Vzemite del natrijevega nitrita, izvedite destilacijo in preverite na kondenzatorju, ali so na njem kapljice nitroetana.

mislite refluks za nevtralizacijo, nato alkainizacijo, upam, da v želji, da bi TRIPLI EKSTRAKT s sep lijakom, nato pa dobro posušili nad anh. MgSO4>dekant > koncentrat=> (solvatirana oblika demonskih protodrakonskih inceptov>uporabni incepti.)
