Problems getting A-PVP to crystalize

[madmoney69]

Hello.
I did a-pvp synth from purchased
2-bromovalerophenone. So it was pretty simple reaction.
Now I evaporate most ethyl acetate add acetone get ph to 5 and I cant get crystals to form. Tried scretching glass, evaporating more solvent but still nothing.
Anyone had experience dealing with this issue?

What solvent you’ve used?

Ethyl acetate.

madmoney69Evaporate the solution until a film appears on the surface. then leave overnight in the freezer (-18/-20C). everything should crystallize
