There was a little oil floating on top of the water
And there was a benzaldehyde smell
This picture after heating for four hours
Then separate the aqueous layer, pour IPA and Put it in the freezer for 10 hours
And this is after shaking
No crystals appeared, then I evaporated I PA at room temperature, added 2.5 ml of acetic acid, and put it in a water bath at 80°
I think I'll throw it away and try again
Should I put more acetic acid like 6ml
(10ml benzaldehyde,10ml nitroethane,6ml GAA, and 3g ammonium acetate)
