I had success with 20320-59-6 liquid form but not with 5449-12-7 powder yet but I will get it for sure ;-) making some tests
Hello again,
After having some problems with the temp of the phosphoric route I decided to make small scale to test the traditional synth for BMK glycidate with HCL.
BMK 5449:H2O:HCL(37%) 1:1:3
- Solve the powder in hot water
- Add the HCL and reflux 5 hours with stirring(you can stop stirring at 2 hours for example and if it's still powder undissolved in the bottom you can add more water)
- Separate the 2 layers, wash with water the oily layer and separate it.
- Add DCM to the water layer and separate it.
- Add the separated DCM to the oily layer keep it before.
- Add anhydrous sodium sulfate to the mixture, stir and filter it.
- Evaporate the DCM.
- Now you have clean B-oil!
What was the yield? Was the yield higher from Phosphoric Acid or HCL?
And what was the reflux temperature? Also 150-160C or only 120 degrees celsius?
Yield is more or less the same like with phosphoric about temp is 80-90C.
Dear btc Boss thank you very much for sharing your experience, can you tell me step for step how you make from the b-oil clear amphetamin base ?
Thank you, but in the end of this synthesis the oil is yellow not clear/white
I know both of them and know both are made from bmk/apaan but can't figure out when it will get clear/white

cas 5449-12-7 has been tested on following procedure:
500g water, 500g bmk and 700ml phosphoric acid 75%
-----------------------------------------------------------------------------
at first i tried to add only 250ml water and 500g bmk powder but the bmk didn't dissolve and started to burn a bit so i added another 250ml water
and then the bmk finally dissolved
why is the oil now milk color? why is it not light yellow color like it was when it was converted?
and why was the yield so small? because of too much water added?
please guys share your experiences what it might be
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.

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?
But after washing it with water it became this milk color
do you boil 2 liters off water for washing ?
when you add the boiling water to the P2P it must be cool down completely before separate
I wait 6 hours for doing this
