2 20%of the total weight of the the product dh20 recrystallisation eg 1000g MA add 200g of dh20 heat dissolve then place under UV black light
And I tell you straight don't try and belittle me and try and make me look like ,I don't know what I'm talking about ok

Lordoftheshard20 years of experience has teached you to put a blacklight on a aqueous meth solution to selectively crystallize d-meth? Publish that shit in the Nature journal buddy, it's ground-breaking. What selectivity - if I ignore all the other nonesense for a minute - would a UV light have on the D-meth molecule vs the L-meth? None, because it is excited exactly the same, it has all the same physical properties.
I don't know why you try to take this people in your fantasy world but it's shameful to be honest.

Lordoftheshard1. 1000g MA its free base or HCl ?
2. dh20-this is distilled water ?

L-tartric will precipitate L-tartrate D-product(y)😤🤑

D-tartric will precipitate the D-tartrate L-product(n):sick::sick:

Either one you use they are still separated, no?

Also I didnt know u were working with racemic product, that will not grow "shards" ever.

Tried to acidify and crystallize relatively small quantity of MDMA freebase.

The weight of the freebase after extraction and ether purification is 40 gr. Calculated volume of HCl = 16.41ml.

The intention was to add the acid, then heat it up to 130C, and drop into the acetone 5-10 volumes and leave it in the freezer.

This time I did it very slow for some reasons, but involuntary. So all the acidification took approximately 30 minutes against planned 15. Magnetic stirrer was used intensively. Resulting PH=2.5

Then when approaching planned volume, I relalized all I have in the beaker on the stirrer is pure white powder. I dropped it in some volume of frozen acetone but rather to wash it as it doesnt look there is any more to crystalize.

Probably all the water evaporated due to the heat released when the acid dripped.

Not sure is it good or I made some serious mistake?

Policja Polskadid you do this crystallization with heating? or with negative temperature? Could you explain to me how I crystallize the free base at negative temperature

kharpa177of course I didn't heat it intentionally. the heat releases itself as the result of acidation.
in my case the mistake was to do it too slow: try to finish all the estimated volume of HCl in 15 minutes.

Policja PolskaYou have to avoid local overheating. The reaction (acidification) time don't play role in this procedure. Temperature and well stirring are main characteristics, which has the most effect on the reaction.

Policja PolskaHello, dear. I would like to ask you why do you heated the solution? It isn't needed. Also 5-10 volumes is too much. 1-3 is okay.

What is concentration of your acid? 35%? You need about 18 ml in this case.
Calculated volume of HCl = 16.41ml.

It is okay

It is not okay. Too low. 5-5.5 is the low point, which is recommended.
Resulting PH=2.5

G.Patton36-37% acid
any way I was mostly watching as the color of freebase changes, and it fits
I didn't heat while dripping the acid. It was used for the stirring only.
2.5 it was the solution, the salt itself shows 5.5.

Hello Patton, bear with me please as this is my first comment, or question rather. I have tried repeatedly to purify mamph by recrystalization, and failed miserably. I just keep wasting product. I am struggling please help with a process! This was my last attempt in attached file.

Meth base will quickly react with carbon dioxide in the air to form the carbonate...
G.PattonDoes this meth carbonate give a kind of yellowish hue to the whole solution? I noticed how the free base turned slightly yellowish after a night in a beaker.

As I remember, percentage of CO2 in the air is 0,03-0.045%.
Molar mass of CO2 = 44.01 gr
Density of CO2 = 1,9768 kg/m3 = 1.9768 gr/L
1.9768 x 0.03 / 44.01 = 0.001344
1.9768 x 0.045 / 44.01 = 0,002021
Then, moles of CO2 in the 1 litter of air shall be between 0.001344 and 0,002021.
If the container is hermetically sealed, the losses should not be significant, should they?

Policja Polskaamines turn yellow or darker when exposed to air and leave a white residue as they evaporate

Is it crazy to add aqueous HCl to a toluene solution with meth freebase in it, seperate the water layer and evaporate it? Meth salt should be in the water layer?

Hi, i have mistakenly added excess hcl acid on my freebase and my oil has changed to dark red, now its not crystallising. Should i add NaOH and water to turn it back to freebase or is there any alternative way i can do

hunter12Hello. Yes, make it back basic and re-extract with DCM. Then, evaporate solvent and repeat procedure without mistakes.
