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 slowly add 1kg of BMK salt. then add 1 liter of sulfonic acid. now connect the reflux and heat the contents of the flask to max temperature. plus minus 130°c. use a powerful mixer
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 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?

After acquiring possible P2P from this reaction, would bisulfite adduct confirm that it is in fact P2P? or are there other ketones that could possibly result from the procedure?

I don't know why it happened with your p2p. How do you store it? In an opened bottle under sun light? You can steam distill it, it should help to save part of this.

I don't know why this happened, I sealed it and stored it in a cool place. Do I need to add distilled water for distillation? At what degree is the temperature controlled?

Watch video about d-meth manufacturing, there is video tutorial how to carry out steam distillation of P2P.
