Phenylacetone (P2P) synthesis via BMK ethyl glycidate

[chem19]

@G.Patton hello,
Need your blessings and support.
In step 6 NaOH solution 30% 450 ml is required.
I have NaOH pellet. How much of these pellet are needed with how much water, to make desirable 450 ml solution.
Plz guide me, as I m getting different different answers.
Thanks in advance
Regards

Hello
450*0.3=135g of NaOH is loaded into the beaker, add there water to reach 450 ml risk.

@G.Patton Thank you so much. You are best. God bless you. If I succeed i will definitely contribute to your bb project. I wish if I could be your experimental chemistry student. Thank you so much again.

Anyone tried the new BMK Oil? cas 41232-97-7. A decade ago you could just get BMK powder make a solution with methanol 1:1 and drip it straight into the al/hg you would be done same day.. is hydrolysis required with all the new BMK derivatives? 5449 sodium salt sucks compared to the old school BMK.

 

[G.Patton]

You need to carry out alkaline hydrolysis and than acid one as for PMK glycidates.
It isn't true, you couldn't make meth from BMK glycidic acid sodium salt directly. You need to get P2P at first.

I'm not saying it was a sodium salt, I know it wasn't a sodium salt the texture of the powder looked totally different consistency from BMK derivative 5449.

Hello experts, this is my first Post. Hope I will get response.
I got 200 ml glycidate ester
My question is how much sodium hydroxide solution,water and solvent should I use in step 11,14,15,
And HCl in step 18. Thanks

@G.Patton will I get a reply.i m noob. But I have chemical access

 

[G.Patton]

You can calculate them by yourself. It has a direct dependence and can be scaled down proportionately.

 

[guideme]

G.Patton Plz correct me if I m wrong
For 700ml of Glycidic easter, you used 450 ml of 30% sodium hydroxide solution,
so for 200 ml I have to use 128.5 ml sodium hydroxide solution, and 142.8ml distilled water and 142.8 ml toulene.

Or if something else.plz notify me.

 

[G.Patton]

How did you calculate 700ml number? From this batch, you'll get in theory 658ml of glycidic ester (100% yield). In a real synthesis it will be less.

proportion is correct but you need to take not 700 ml. Count it for 530ml (for instance 80% yield).

HCL addition is usually 2-3 times the amount of the glycidate powder or doing it by eye you add HCL slowly until it stops reacting with the water-glycidate solution.

Does the BMK oil=P2P produced using this process need to be further distilled and purified?
Or can you directly use BMK oil to make methamphetamine free base?

 

[chef learner]

Is there any teacher who can answer this question? I need to clear up my doubts.

What is the quality of the P2P made using this method? I started with dimethylformamide, but according to the process and the teaching in the video, the color of my finished P2P seems to be very light. What is the reason for this and what will affect it? Will the results of the methamphetamine free base test be followed up?

Iv had similar p2p surprise after hydrolysis too however mine was with poor quality BMK powder and the end product was quite weak.

[chef learner]

Does every reagent used have a chance of affecting these? Or is there any reagent in the list that I need to replace?
I always use the same method, but this time it is different. It is obviously darker, but I don’t know which part affects it, because the time, quantity, and process are all the same.

 

[Throw-off]

Your forgetting the main one that would effect it.. Temperature

 

[Teotaita]

GPATTON just too be clear “19. The mixture is heated to 60°C and decarboxylated with constant stirring for 5 h.”
Is the mixture heated the whole time at 60 C or once it hits 60 C is the heat turned off with only constant stirring for 5 hours?? Thanks

 

[Manisj@1290]

I'm a little confused, this is BMK yield 300 ml, is it p2p or BMK oil

 

[G.Patton]

What do you mean? BMK mean benzyl methyl ketone, that is the other name of phenyl-2-propanone (P2P). You can google it easy or open BB Wiki to read...

 

[Manisj@1290]

Sorry I have little knowledge, I want to know that with the help of this video I can make methamphetamine from the BMK oil that I get.

 

[Manisj@1290]

I have BMK Glycidic Acid (Sodium Salt) (CAS No.-5449-12-7) in powder form, how can we make it P2P

 

[chef learner]

Search for P2P synthesis of BMK glycidyl ethers

Or read more in the reply area. There is also a way to make P2P by phosphoric acid hydrolysis. Choose the reagents you can obtain and then choose the method to avoid going astray.
