can anybody provide me receipt to it

When 10 grams of Benzaldehyde + 10 grams of MEK and 7 grams of 30.5% aqueous HCl are mixed for 24 hours at room temperature, I obtain an organic layer.
The reaction should be carried out in an inert reactor, and the mouth of the reactor should be sealed with an inert stopper (such as LDPE, Teflon, glass, etc.).
I wash the organic layer with NaHCO3 solution until it is neutral and put it directly into the freezer. No heating. I filter it using a vacuum cleaner motor. This separates the remaining residual Benzaldehyde and MEK. White crystals remains behind.
When I pour -18 degree methanol on it, I obtain completely snow-white crystals. In my last test, I used 50 grams of Benzaldehyde + 50 grams of MEK and 35 grams of 30.5% aqueous HCl. I obtained 46 grams of snow-white crystals.
Methanol must be cooled in the freezer. Otherwise a lot of crystal will dissolve in the washing step.
I also think you can use ice water when washing, but I haven't tried it yet.

My "P2P" smells very much like "burnt" benzaldehyde. After a while it starts to resemble apple flavor. There is also a very light honey note. But it smells predominantly like burnt benzaldehyde. And it takes hours to steam distill any usable amount. If I hydrolyze the ester separately with NaOH solution, a very dominant methyl acetate smell is emitted from the mixture.

What I mean, is not to be an ass. I have just seen very weird questions lately. Like how do you make a compound from a to b to c, when the whole procedure is known in here, or at least written the whole synthesis procedure in here! All I can say for those kind of ... weirdness is that I don't know shit about nothing.

Instead of asking non-specific questions like the village lunatic to everyone who comes by, go and do some literature research. You're getting annoying. No one is going to teach you things step by step. If that's your expectation, don't bother waiting. Everyone puts in effort, and no one is willing to teach someone who doesn't even bother to read. You keep asking same question after another even when the answers are clearly given.

Like I have said before, of course I'll help you, or someone else with synthesis problems, if I can help, but if the question is can you please tell me how much you made something/anything this week, all I can say, nada. Giving you the yield from some compound will actually help you?! Please ...

"I don't just understand where did you get the impression that I was asking anything here...?"
That reply was for AKINCI. He constantly asks something but never reads the answers and keeps asking the same thing.
