Need help convert bmk 5449-12-7 to free base A-oil

[Zan444]

I cant read this anymore.
What you want is the Amphetamin Freebase this is A-OIL not N-Amphetamin you want normal Amphetamin.
It looks like that BMK Powder (Cas:544.....) -> BMK(P2P)(B-OIL) -> N-Amphetamin -> Amphetamin(Amphetamin freebase)(A-OIL) -> Amphetamin Sulphate made out of A-Oil,Solvent and Sulfuric Acid.
You have now N-Amphetamin made out of Formic Acid now you need to make Hydrolysis for example with HCL to get the Ampehtamin Freebase. At the end you need too purify the Amphetamin Freebase to get your clear oil maybe you get 2 or 3 diffrent oils depends how you work one yellow and one clear. Both A-Oil of diffrent quality.

@serialz And no N-Amphetamin is not A-OIL. A-OIL is Amphetamin(Amphetamin Freebase)
@Saul do the step with the HCL if you need more help ask me. You have now N-Amphetamin so one more step and you have A-OIL

How do you mean that exactly that two different oil qualities can be extracted from a single process?

 

[Saul]

Hello, thanks for your reply.
serialz was indeed mistaken in saying that N-Formylamphetamine was A-oil.
He rectified this afterwards with the help of G.Patton .
I just finished adding hydrochloric acid
all i have to do is raise my PH to 11 and wash with toluene .
and I wanted to finish with a distillation .

I have a question about distillation. can i just distill the oil without adding anything?

 

[Saul]

This topic is stuck for weeks

 

[melk]

it's a complete failure. i had natrium hydroxide cas 1310-73-2
150 gr mixed with 300ml water .
let cool to room temperature.
then added to my mix see previous photo
and now it fucks up i have 3 layers my
bottom white salt middle translucent and top black yield is almost gone now
pH has not changed. but also very difficult to measure a black thick liquid with those strips.
fucking shit

compleet fail becouse off natrium hydroxide

is it possible that this fuckt up mix need to heat and reflux for an hour ?

 

[KokosDreams]

I'd assume yes, it will remove unwanted liquid by-products from the oil and you can also use a DCM extraction to get rid of unwanted solids

 

[melk]

..

 

[UWe9o12jkied91d]

freebase is air and temp sensitive, if you want to distill you need to do it under vaccum or by steam.

 

[KokosDreams]

As for the distillation, yes.

But a DCM extraction can be done aswell right, to get rid of solids?

 

[UWe9o12jkied91d]

It's either or as they are both a way to isolate your product, or both, I guess, if you want it super pure.Extraction with solvent will have more impurities but it does the job and you can purify after precipitation or pool extracts and rotovap the solvent under pressure.

 

[KokosDreams]

I'd actually do all of the following steps to purify the oil as much as possible.

1. Evaporate IPA with a Rotavap
2. Add water (1:1) for steam distillation
3. Extract distilled mixture twice with DCM (250ml:2L)
4. Evaporate DCM on Vacuum with a Rotavap

 

[UWe9o12jkied91d]

sounds good, let us know how it goes

 

[KokosDreams]

Yeah man,

I'll be good to go once all the lab equipment arrived - which might be approx 3 weeks from now.

I'll publish a short post public on the forum and a more detailed one including pictures in my group

 

[Saul]

Iam just ready with the final steps.
but it is a total failure.
I added sulfuric acid to my mixture or methanol + A-oil and I had no reaction at all. my A oil had ph13
everything seemed fine. but no reaction at all with addition of sulfuric acid. ph is drop back to 1 thats it
after adding hydrochloric acid to my N-formylamphetamine boil for two hours.
then I separated the layers. I made a mixture of 300gr NaOH + 500ml water .
added at room temperature. Boil at reflux for 30 min. layers separated ph was 12 or 13
Then I washed 3 times with toluene. I had put the top layer in a glass bottle with toluene and shaken well. this 3 times again . then i did the distillation and everything seemed ok

zero reaction heavy disappointment

I am sure that something went wrong after the preparation of N-formylamphetamine .
the part of hydrochloric acid addition nobody here knew what to do . and then you just act blind. they post explanation add 5ml hydrochloric acid and 5ml methanol . then the question is asked 5ml to 100ml?? 1000ml?? answer I don't know.

 

[Zan444]

If you make steam distillation you can get alot of diffrent oils cause it is not that easy too hold the temperature. It is A-OIL but one is of better quality then the other.
Or why do you think they sell 2 diffrent OILs in europe one yellow other clear. There are even diffrent namens for the OILs in the netherlands.
Can you writte down all the steps you made in a post so i can look over it to find some misstakes?

 

[KokosDreams]

Interesting.

What measures can be taken to improve providing a steady temperature?

Also, what are the street names of these two different oils?

 

[Zan444]

Smaller amounts and vacuum distillation.
I dont think someone here performs vacuum destillation on 200L.

 

[KokosDreams]

What would be a smaller amount be for you (maximum in L)?

Also, can you recall the most common street names for both different qualities?

 

[Zan444]

For street names hit me up in private message. They are also just known in the netherlands.
It doesnt depend on the L it depends on the equipment you have.
If you have a distillation device for 200L what allows vacuum distillation it should be possible for 200L but i dont think it is done that easy.
The answear is most big labs use steam distillation cause it is more easy too perform on big amounts.
But you have still the problem with the temperature on big amounts.
