The brown red color oil is the unreacted glycidic acid, it would be best to steam distill the ketone then use in the next step

You need to explain step by step what you have done

I am going to make 100 gr scale, then 150 gr, then maybe 200 gr. With 50 gr scale, I am going make it couple of times while varying the amount of acid and water to find the optimal amount to add. This will be my project now, I will keep updating the thread with the results I get.

The distillation of p2p begins immediately as the drops are added, by the time you finish adding, the reaction is complete and you have pure product in the receiving flask. It takes about 1 hour I agree it might not be economical for big scale since it requires a lot of water and excess acid.

Yes Claisen adapter. I used 100 ml for 50 gr batch, excess acid is to prevent the formation of layers in the flask and to make the reaction go on immediately, this minimizes the formation of byproducts. The amount of acid can still be optimized to make it economical. When I had less acid, I...

Introduction This is the modified preparation of P2P CAS 103-79-7 made using BMK Glycidic Acid ( sodium salt ) CAS 5449-12-7 with Phosphoric Acid 85% CAS 7664-38-2 Equipment and glassware: 1000 ml 3-neck Round bottom flask Distillation adapter Condenser with a receiving flask Dropping funnel...

Yes I will publish the methodology after running 50gr batch, the 12ml p2p from 20 gr sodium glycidate was dry

Thank you, I have sent the message, please respond

This is the p2p oil (I think) from the receiving flask , the mixture is still cloudy, I left it to separate into layers overnight (hopefully). With the unreacted glycidic acid, I am planning to extract it and see if I can get more p2p by hydrolising again with the acid, using strong mixing...

@Sweswe @G.Patton

I have gotten the same result using phosphoric acid 85%, the temperature was max, I refluxed for about 4 hours. I think the problem was that my mixing was not sufficient, plus I stopped stirring when the reaction mixture started boiling (I honestly thought the boiling would provide sufficient...

Congrats on successful synthesis, I look forward to seeing your pics

Hi stim2023, was your yield consistent with the one in G.Patton method? Also did you experience any problems or unexpected results in the synthesis?

Hi sponsor, so water is really not necessary? Can one start by adding the BMK salt to warm/hot acid and starting the reflux?

Hi T0R, what should the PH of the reaction mixture be?

Hi Sjeik, what was your B-Oil yield from 1Kg BMK? After finishing, is the 0.5L H2O just pure distilled H20 or brine solution? Lastly, what temperature should the H20 be?

Hi btcboss2022, is it possible that you can re-upload/share these videos if you still have them? Also, did you use reductive amination via Al/Hg to obtain the 800gr meth oil from B-oil?

G.Patton?, HEISENBERG? Anyone?

I came across this video on YouTube. They just mix benzyl alcohol with ammonium bicarbonate, and apparently you get methamphetamine. There is no P2P or methylamine or any other precursor used in this method. Is this practical/feasible? Can anyone explain the reaction mechanism behind this...
