How much acid and ethanol did you add?
How much water did you add?
Next time no one answered you, I told you to mention the synthesis in detail so that you know what is wrong with this
In the neutralization part, I added about 70, 80 or 100 ml of water, then I added 50 ml of distilled water, ie 200 ml of ethanol, 100 ml of sulfuric acid to crystallize.
Make sure that it may have decomposed due to the heat. Take the sodium nitrite part, make a distillation, and check the condenser, if there are any nitro ethane drops.
you mean reflux to neutralize, then alkainize, I HOPE IN ORDER TO TRIPLY EXTRACT with a sep funnel then dried well over anh. MgSO4>decant > concentrate=> (solvated form of demoniac protodraconic incepts>useful incepts.)
