edit // VERY slowly in a liter of 80°c phosphoric acid (NO WATER)
SaulDo you use H3PO4 cons or diluted solution? Thank you for your feedback.

G.Pattonsame question, i used h3po4, 98% con, and get the p2p, but after i burn the p2p, it left white powder. but as i know, p2p, if burn, leave nothing

I got BMK powder but not sure if sodium salt, how to tell the difference between each?

BamBamsalt is water soluble. acid and glycidate are not. salt has pretty high melting point, acid and glycidates are below 100 degrees

Ortistwow I've been looking for exactly this information. I have glycidic acid that is not water soluble, how do I turn it into the sodium salt? because the way it is I can't put forward the described processes.
Also, what are the CAS numbers of glycidic acid and glycidic acid "sodium salt" ( Is this the correct definitiion?)
I am told I have 5449 but it is definitely not water soluble and this is probably the deadlock I'm in

Thank you for the information.

orgasmatronif your powder is not water soluble then you have either acid or ester. Both can be converted to the salt by treating it with NaOH just as described in the very first message of this topic. Step 1.

Someone can explain me. In this video used what. BMK glycidate ether or BMK methyl glycidate or BMK ethyl glycidate or BMK glycidic acid.

Sorry I got another dumb question!
When skip step 1 and start at acid hydrolysis cause have the sodium salt,
Do I start by adding the Bmk then start with small portions of acid 200ml?
Just not sure if I should be dissolving the salt in water before start with acid or acid straight onto salt?

In reagents it’s 80ml hcl but step 2 it’s 200ml hcl?

BamBamI have no idea how they guys on this video got the yeld they got. My experiments with HCl were low yelding. You need reflux temperature, huge excess of an acid (1:3 by weight) , good stirring and long reaction time.

Some people say they have success with HCl. I only had success with phosphoric acid

OrtistYeah I got Fuk all from first attempt, will try again with phosphoric acid.

Introduction

Hydrolysis of BMK glycidate ethers is represented in this topic. The procedure is the same for ethyl (Et) [cas 41232-97-7] and methyl (Me) [cas 80532-66-7] esters of glycidic acid. In case of sodium (Na) salt of this acid [cas 5449-12-7], you can skip first stage of NaOH addition and start from acid hydrolysis. In addition, purification method of obtained P2P is described. This procedure have to be committed to get pure Phenylacetone (P2P) for further syntheses of methamphetamine or amphetamine.

Suppliers of BMK glycidate ethers can be found in BB Listing.

Difficulty rating: 2/10 View attachment 6617

Equipment and glassware:

Reagents:
  • 100 g BMK glycidate ethers (cas 80532-66-7; cas 41232-97-7; cas 5449-12-7);
  • ~20 g NaOH or KOH;
  • ~80 ml HCl (35%) or 100 ml H2SO4 (45%);
  • ~600 mL DCM or Petroleum Ether;
  • ~100 g MgSO4 or Na2SO4;
  • ~500-600 mL Distilled water;
  • ~ 50 g NaCl (optional);

Hydrolysis of BMK glycidates

1. NaOH (or KOH) 20g is dissolved in 250-300 ml distilled water with stirring. The reaction mixture (Rm) have to be cooled to room temperature. BMK glycidate 100 g (methyl or ethyl ester) is added and dissolved completely. Part of BMK is hydrolyzed during this procedure and floated as an oil in the surface of Rm. Rm is stired for 1 h at 75-80 °C with a reflux condenser.
2. Then, 200 ml HCl (35%) or 240 ml H2SO4 (45%) are added in small portions to Rm and heated to 80-90 °C and stired for 3 h. Rm have to be cooled to room temperature, the precipitate is filtered.
3. The reaction solution is extracted with DCM or petroleum ether 3 x 100 ml. Extract is washed with brine to neutral pH 7 several times. Extract is dried with MgSO4 (or Na2SO4) (optional) and filtered from solids.
4. An organic solvent (DCM or petroleum ether) is distilled off to give 65 ml of P2P.

Phenylacetone (P2P) synthesis via BMK ethyl glycidate

P2P purification

1. The resulting phenylacetone (P2P) is transferred to a round bottom flask with distilled water 1:1 (w/w) and distilled with steam under vacuum.
2. Purified P2P from receiver flask is extracted from water mixture with DCM (or petroleuum ether) 3 x 100 mL. Extract is dried with MgSO4 (or Na2SO4).
3. The resulting solution is filtered from the solids (drying agent) and then an organic solvent is distilled off.

Phenylacetone can be stored long time in a sealed vessel in a freezer. It is recommended to distill it before further syntheses of methamphetamine or amphetamine. Avoid direct sunlight onto phenylacetone and exposure to high temperatures.
G.PattonHi sir. I have few question to ask.
Is it must bmk turn to p2p first. Then p2p turn to amphetamine. The last is amphetamine turn to methamphetamine?

I got confused over the sulfonic acid part. I understand he was using phosphoric acid.
I now have sulfonic acid. Not phosphoric. Can sulfonic be used?
Anybody try it? Results?

jessejames122669All 3 acids (hci/phos/sulf) work, but there seems to different results in yield and different experiences. Every one has its one temp and time to convert and maybe prufication necessary.
