need help converting 5449-12-7 and 20320-59-6

[Bartholomeus]

Hello,

Obviously the best yield of amph from P2P is converting it in A-Oil(Amphetamine freebase) and make the sulfate from it.
From a good A-oil you can get 2.8kg until 3kg of amph sulfate ;-)

Sorry you understood my question wrong, I was asking what gives the most yield % - reductive amination method from p2p to amphetamine?
Other than Al/Hg or Leuckart Wallach ?

BartholomeusThis should answer your question

 

[btcboss2022]

Thanks for picture, the ''dirty'' oil is the middle layer - that ''black - brown layer'' of oil?
And what is the first and last layer? Why is the oil on the middle and not in the upper or downer layer?
I thought with this conversion only two layers form?
From 14 liters of dirty oil, you obtained like 11.2 liters of pure and clean P2P right?
What was your method of cleaning? Which type of destillation?

ChingShihMiddle layer? There are only 2 layers and the oil is the top one.
Yes around 11 liters:
- Steam distillation.
- Separate oil from water layer.
- Extract water phase with DCM.
- Dry with sodium sulfate and filter it.
- Evaporate DCM.

btcboss2022Will vacuum distillation work for the top layer instead of steam distillation?

 

[Jordan Belfort]

I don't use a small one I use a big one. But I don't distill P2P at vacuum normally.

btcboss2022You do reaction with the phosphoric still in the BMK ? Or you wash with water?

Jordan BelfortI wash it with a bicarbonate solution.

btcboss2022What solvent on 1L, becuase baking soda is not very soluble in water unlike natrium chloride?

what is the ph off your milk ?

if you follow my instructions step by step you had no milk

----------------------------------------------------------------------------------------------------
this is the preparation of P2P Phenylacetone CAS 103-79-7 made use of BMK Glycidic Acid ( sodium salt ) CAS 5449-12-7 with main ingredient sulfonic acid strength is 75% CAS 7664-38-2
-------------------------------------------------- ------------------------------
we are going to prepare 1 kg of BMK
take a 5 liter double neck flask
add 500ml boiling water . start with the mixer.
now very slowly add 1kg of BMK salt. ( 30 minutes )
then add 1 liter of sulfonic acid.
and heat the contents of the flask to max temperature. plus minus 130°c. use a powerful mixer.
now connect the reflux
Let it boil in reflux for 4 hours.
take the top layer and pour it into a measuring cup.
let the bottom layer cool and save for next time. ( we have no chemical waste for this preparation method )

now boil 1 liter of water and add it to the measuring cup. use a hand mixer to mix everything.
After mixing for a few minutes, let the measuring cup cool to room temperature.
remove the top white layer (this is water and waste that we don't need)
the bottom layer is P2P purified and ready to use.

ps: in this preparation we don't have to worry about water remaining in our P2P because water weighs less than P2P

ps2: if you keep these ratios, the P2P will have a ph value of 4 .
if you use more sulfonic acid the ph value will drop to 1. Therefore it is not necessary to use too much sulfonic acid.

Saul
I have to measure the ph of my milk
Maybe i added to much water, but the problem is the 250ml water at the start wasn't enough to dissolve 500g of bmk powder
So i then added again 250ml of water, and then everything dissolved smoothly, after that when bmk dissolved in water
i added 720ml of phosphoric acid 75% to the flask, and proceed to boil reflux for 4 hours
after 1 hour there was already the oil on top, but i still made the reflux for 4 hours
and after it was finished, transparent-yellow oil was on top
But after washing it with water it became this milk color
i don't know why, and the yield is only 40% which is very bad i know this
Next time I will make experiment with: 300ml water, 500g powder and 1L of phosphoric acid 75%

what is your yield @Saul from 5449? 60-70% after washing with boiling water?

BartholomeusHey buddy, was wondering if you figured it out how to turn BMK powder to P2P if so is it possible to get the recipe please having a hard time with it

Cas 5449-12-7

 

[Mr.blank00]

My inbox is messaged if anyone needs help converting 5449 to p2p...

 

[Berlin777]

I tested 5449
5449/HCl 36%/H2O 1/1/1 4 hours in 90-95 C, I been advised by an expert to use less acid

Berlin777I've attempted without successful results. Phosphoric is best imo.

One moll of your 5449 to one moll acid,and about 1,5 liter water per kilo 5449. Heath it up to about 50 to 70C ,and let it bubbel out the Co2. Bubbels stop (foaming) reaction done,
Sepp the two layers,top one is your oil,Wash it several times with boiling water and/or brine and dry over NaCi or dryed out epsom salt (in oven dryed) and your good for next step

edyvanellendeAccording to the experts a little bit excess of acid is needed in molar ratio. Also these temperatures didn't work for me and P2P crystallized few days later. I had to heat up to over 90 C. I will try your method as well as I haven't cooked too much P2P yet so it's worth to see what works best for me.

Bit late i see now,sorry for that
