Recristallization of methamphetamine

[JimMoriSon27]

Hello, I recently tested a recrystallization technique for methamphetamine that apparently works quite well.

I found it on a forum.

Procedure:

Put the meth in a container and add acetone (anhydrous if possible) about 1 -2 cm above the meth level.

Heat until boiling, then add alcohol (I use IPA) until the meth is completely dissolved (or almost).

Remove from heat source, cover with a layer of aluminum foil, then a layer of cling film, and cool for 1h in a tepid water bath.
Place the container in the fridge for a further 1h, then in the freezer for 24h.

Personally, I stop at the fridge because I use small quantities of methamphetamine and I haven't seen any additional results after 24 hours in the freezer...

And that's it, you should be able to find little crystal meth needles when you're done!

Here are pictures of my result

Still using the same technique, here are my latest results.

I dissolve it in boiling IPA and add acetone until it just starts to cloudy. The results are exactly the same though. After the 2 hours in the freezer or whatever, evaporate it down to 50% and cool it again

 

[JimMoriSon27]

Cool, I have to try that too. Thanks

 

[Mr Good Cat]

Interesting. What are your approx proportions by weight and volume - meth : ipa : acetone ?
and what is aprox yeld after first re-crystallization?

 

[JimMoriSon27]

For example, for 40g of meth and 1dl of acetone heated to 52-54°, an average of 9.5ml of water is enough to dissolve the whole. Then I leave to cool for about 3h at room temperature, 1h30 to 2h in the fridge and finally a few hours in the freezer. The result obtained after recrystallization is about 95% (on average 2-3gr loss).

Thanks. Interesting. I also love this re-crystallization in 10% water/acetone solution. I used it for mdma hcl re-crystallization a hundres of times, but in this case the yeld is around 80-90% in 12 hours. To recover rest you shall evaporate most of liquid and repeat it again.

 

[JimMoriSon27]

What is the process for the 10% water / acetone solution?

 

[Mr Good Cat]

simple: 10% H2O + 90% acetone. hydrochloride is dissolved in this solution, then moved to the freezer.

 

[Mr Good Cat]

For small amount yes. If we are talking about 20-50 gr, it is OK to recrystallize it in water/acetone in a half of a day.
But for bigger amount more time required.
Right now recrystallizing around 500 gr of mdma hcl in water/acetone. After 24 hours yeld is 83%. Around 85 gr are still dissolved. I guess it will take more 72 hours to take them out.

Good morning sir.
Is the recrystallization method you mentioned applicable to methamphetamine hydrochloride?

[JimMoriSon27]

Yes

Dear Mr.

I'm a beginner and experimenting. I have failed many times when it comes to crystallization.

Can you answer a few questions for me?

1. Did you crystallize racemic or D-methyl?

2. What are the ratios of methyl/acetone/isopropyl alcohol?

3. The cooling issue you mentioned. Let cool to room temperature first. Then cool in the refrigerator for 1 hour. Cool in the refrigerator for 24 hours. I do not quite understand. The difference in refrigerator temperatures. What is the temperature of the refrigerator during the 1 hour cooling process? What is the temperature of the refrigerator during this 24-hour period?

gentlemen. Thank you very much!
wish you a happy life.

 

[JimMoriSon27]

1. It s D-methyl I think. I m not a chimist and never did analyse of it but it should be this one.

2. Using acétone and water, about 20g of meth, I use 1dl of acetone and heat it just befor the boiling point. Then in average I use 8 - 9.5ml of water and stirred well until nearly all meth is dissolved.
Then I cover with aluminium foil and cling film and wrap my container with 1 kitchen towel to slow down the cooling process.

3. At the moment I leave to cool for 4 to 6 hours in the open air, depending on the quantity (10 - 20g).
Then either I collect the shards before continuing the cooling process in the fridge (mine is set at 3°C) and then in the freezer, or I put the whole thing directly into the fridge and then the freezer...
If you only let it cool at room temperature you will lost a lot of product.
Continue cooling as described to recover as much product as possible.
When no more crystals form, evaporate the liquid to recover as much as possible.

I usually collect the crystals formed at room temperature before putting them in the fridge, as cooling in the fridge is quicker so the crystals become smaller.

Voilà, I hope I answered your question..
Otherwise tell me.

Cheers

Hello sir,


I keep having the same problem i really hope you could help me.

I also have d-meth and use your method and had succes one time. After i repeat the proces with the same meth i keep having the same problem over and over. If you could give me some advise, it would be much appreciated !

While crystallizing the crystals stick around the side of the beaker and look alot like mdma when finished. I dont understand why it does that and i'm wondering if you ever had the same problem. If so, what did you do to fix it ? I repeated the proces many times but i keep getting the same results. Any advice is welcome !

 

[JimMoriSon27]

Do you use anhydrous acetone and distilled water ?
If yes, did you add the water all in one time or little by little and even drop by drop until almost everything has to be diluted?

 

[bordello]

What do you mean by sealing? Luke wrap foil and tape around the container with no hole like sealed sealed ?

 

[hacke8]

There is no need to be so strict. Just wrap it with aluminum foil normally, mainly to prevent dust from entering and slow down the evaporation of the solution. The slower the evaporation, the larger the crystal. Rapid evaporation will only form crystalline powder.

 

[JimMoriSon27]

You can also use IPA or either vodka t dissolve product but I have best result with distilled water..

 

[qwe111]

Yes, sir. Thank you for your generosity. I'll try to do it.

Cheers to success.
