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

so you wa
so you want to make P2P from BMK salts?
what do you use for chemicals?
HCl does not work!
I know it's all over the forum, but it doesn't work at all
you need a chemical with a much higher boiling point for good yields
and use enouch water to start with becouse
the water evaporates first because the boiling point is lower
you need to start reflux when the temp is higher than 130°c
then you know the water is gone and then you boil in reflux for 3 hours

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

@ChingShih hello my friend. it is hard to know what you mean without pictures
but my first attempt ever, i had a white salt coating on the bottom of my p2p.
this was because I had not taken into account the PH values.
my pH was so low that my mixer rod was completely dissolved.
therefore, it is very important that you always measure your pH.
if your ph is to low you need to add more bmk salt to the flask
if your ph is to high you need to add more acid
in subsequent attempts, I have not had this problem again

 

[Heisenblack]

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

 

[Saul]

How is it possible that when I extract my final liquid with DCM I dont see two layers but just one ?

 

[Sjeik]

you still need help?

the picture is that What u call A oil

 

[mocnykutas]

Where did u buy it ?

 

[w2x3f5]

It doesn't look like oil or emulsion, it looks like you did something wrong

 

[Sjeik]

Jacked off And disposed in it

 

[John Gotti]

Hi ive had bmk oils for long time now and there is a blocker in them they need to be activated or something. But is it easier to get the bmk powder 5449 and make the oil into A oils but how do u do that

 

[Sjeik]

If you convert it the right way, you Will receive a yellow/brownish coloured oil depending on wich reagent u use. We call that b oil. If you fail doing that it Will be a thick oil that Will turn milky afterwords. So its very important that you convert it the right way, or else your waisting your time and money

 

[w2x3f5]

There is free glycidate or sodium glycidate. The sodium salt is highly soluble in water and they use it for hydrolysis in hydrochloric acid, I have more doubts that all the sodium salt will react quickly with decarboxylation, it will quickly turn back into free glycidate. Free glycidate reacts perfectly in pure phosphoric acid, two important points in the reaction are to obtain a homogeneous mixture and the second nuance is the decarboxylation temperature.

@Sjeik

that looks like mierenzuur + bakkersgist to me

 

[Sjeik]

No its loog And olie mixed with kokend water

 

[Sciencenutz]

What yeild are ppl getting off the 5449? China suppliers are saying 45-55% yeild on 5449 and 2320..

 

[w2x3f5]

60-80, but with HCl 40-60

 

[Sciencenutz]

So phosphoric acid yeild is best?

Hello

I want to convert

5449-12-7 to free base A-oil and to Amphetamine sulphate.​

I have this recipe made by someone.

Only in the ending i dont know how much Naoh sol (assuming this is sodium hydroxide) i need. And i cant contact this person anymore.

Also 24hours seems very excesive.

I have sulphuric acid 96% thats why he created a recipe with sulphuric acid

Also i have formamide, magnesium sulphate. And ofcourse cas. 5449-12-7


Could you maybe give me some guidance.

the recipe:

there is no big philosophy, dissolve that cas in boiling water, switch off heat, add conc. Sulphuric acid, 500ml 98% /kg or equivalent, the more conc. the better, this has to be done carefully but if all powder is dissolved your oil will float to the top or bottom, it dosen’t matter where it goes its easy to tell which is water.Optionally you can further heat this for more yield.Toluene is then poured in to extract, layers separated, filtered of solids if any, dry on mgso4 anhydrous.Your benzyl methyl ketone is ready to be used in solution of toluene as is. Your bmk is heated 3-4h gradually to 80c together with formamide 75-12-7 , then 24h gradually to 160c and kept there multiple hours.Naoh sol is added and refluxed again for 2h, end of condenser vented to outside, you have been warned. After that add naoh again in excess, let layers separate and top layer is product.



Best regards
Brenda

@Sciencenutz yes for creating p2p phosphoric acid is the best

 

[Saul]

so is there someone who became free base at the end?

I got an aneurysm from all the bs a lot of people have written.
Buy bmk (5449-12-7) hydrolise with phosphoric acid (85%) 3:4 (BMKhosphoric acid) (slow addition of the bmk).
Reflux with stirring on 140-150 celsius for 4-5 hours.
Top layer is P2P bottom is garbage discard it.
Wash the P2P with water and brine (optional because sometimes emulsions form sometimes it's clean really depends where you got the bmk powder)
Vacuum or steam distill it. (optional)
Dry with MgSO4 or Na2SO4.
TOTAL YIELD P2P IS AROUND 65-70% OF BMK POWDER USED

Mix P2P Formamide and formic acid 1:1.5:1 (formic acid and formamide are in excess; formic acid is 85% - 15% form/water)
Reflux with stirring for 4-5 hours at 140-150 celsius.
Cool the reaction or wait it to cool on it's own.
2 layers form after - top layer (cognac color is your Formylamphetamine, bottom layer is junk with minimal amount of formyl, can be extracted with DCM)
Formylamphetamine should be slightly more in quantity than the P2P used.
Hydrolise formylamphetamine with NaOH 60-70% (Formyl group has a weak bond it can be hydrolised just with NaOH not the typical Leuckart) ; 1:1.5 by refluxing at 110-120 celsius for 2-3 hours
Top layer is crude amphetamine base, bottom layer is sometimes liquid sometimes liquid-solid junk.
Vacuum or steam distill the crude amphetamine base.
Dry the distillate on Na2SO4 or MgSO4.
Mix the dried product 1:5 with pure dried methanol.
While stirring non stop add dropwise 98%+ H2SO4 until pH 6.5 is reached.
Once reached seal reaction vessel and put in fridge to settle for 24 hours.
Filter through buchner funnel, rag or whatever is suitable at time of work.
Residue in filter is amphetamine sulphate.
Dry it at room temperature and sunlight on big filter paper sheets.
In some cases the final product is yellowish jelly-like due to oxidation, in that case dissolve it in minimal amount of hot pure IPA and put in fridge for 2 hours to cool.
Filter again using buchner, rag, sheets or whatever. The clean white residue in the filter is purest amphetamine sulphate. Evap the filtrate IPA to get the rest amph.

TOTAL YIELD DRY PURE AMPHETAMINE SULPHATE FROM P2P USED IS AROUND 30-40%!!!
YES I HAVE DONE THIS WHOLE REACTION NUMEROUS TIMES!!!
