It shouldn't be possible to lose the nitroacetanilide in the recrystalization. You can only cause it to hydrolyse, if you don't remove enough of the acid. The nitroaniline should be dissolved in the solvent if water is used. Then ethanol can be used to make the ammonium salt of p-nitroaniline precipitate. If ethanol was used for recrystalization, you can try adding some water to make your product precipitate, which is unlikely. If it doesn't work, a lot of ethanol should help.
This seems to work. www.google.com/url?q=www.magritek.com/wp-content/uploads/2015/03/Lab-Manual-Synthesis-of-p-nitroaniline-web.pdf&sa=U&ved=2ahUKEwiCo9bmlartAhVLyxoKHeZEBW8QFjAAegQIBhAB&usg=AOvVaw2JjicHwBG3ZT8ZFrXjFv8b
Doing good work....., appreciated
Adorei!parabéns pelo trabalho!
Why do we use a diluted solution of sulfuric acid ?!
Why yield was low?? I tried this method a couple of times but fail to get such beautiful crystals use of conc acid seems to degrade the final product
How many grams of o-Nitiacetanilide , please🙏🏻
Because I want to calculate the thertical yeild
Any idea what's in the tar?
Thank you. Skinny yield 👍
Amazing
Thanks you 👍
I might not be paying enough attention, but how is this a separation of p-nitroanilin from o-nitroaniline?!
P nitro aniline is insoluble in water while o nitro aniline is soluble
This is a kind of brown color metal?
The brown color is due to organic side-products.
After recrystallisation i lost all of my nitroacetanilide.can you pls tell me what i did wrong?

@@RaExpIn thank you!!!
What technique did you use?
Can you give a link to the source?
Thank you very much :))
It was this manual: www.magritek.com/wp-content/uploads/2013/12/Spinsolve_LabManual_Nitroaniline_Web.pdf
@@RaExpIn Thank you very much!))
@@RaExpIn can u send again please? Link is wrong
This seems to work.

What’s with all the bird chirping?
I don't have a fume hood, so I'm working outside.
How to synthesize me
lol
I used aniline to make paracetamol
Aniline -> acetanilide -> paracetamol
Is this the product p-nitroaniline ? Or p-nitroacetanilida ? Please ?
It's p-nitroaniline :)
I'm from india

Acetanilide is so much impure bad quality. Oxidized.
