Hi. I have a problem with crystallization. After adding hydrochloric acid, the reaction does not crystallize. When you first start mixing the 2bromovalerophenone with the ethyl acetate and prolidine, it looks like it didn't mix well. The mixture was stirred for 1 hour. The layers have separated and it shouldn't be like that. Only later did I add distilled water and the phases separated, but why does it look so bad at the beginning?
Proportion:
*2bromovalerophenone ~760ml
* ethyl acetate 4L
*pirolidyna 1L
*water distillate 6L
*Aceton 4L
*ACID 36% 200-300ml

The problem is that you wrote 4 liters of ethylacetate and etc in the description, but the photo is an order of magnitude less, and you also did not write your work by steps with your observations. I am not Nostradamus to warn your actions and the synthesis itself. Crystallization turned out as I see.
