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!

JimMoriSon27Still using the same technique, here are my latest results.

 

[Frit Buchner]

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

Frit BuchnerCool, I have to try that too. Thanks

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

Mr Good CatFor 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).

JimMoriSon27Thanks. 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.

Mr Good CatWhat is the process for the 10% water / acetone solution?

 

[Mr Good Cat]

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

JimMoriSon27simple: 10% H2O + 90% acetone. hydrochloride is dissolved in this solution, then moved to the freezer.

JimMoriSon27For 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?

JimMoriSon27Dear 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

JimMoriSon27Hello 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 !

Mysticsea3Do 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?

 

[JimMoriSon27]

Yes i used anhydrous acetone but i use regular tap water.

(I use all the ratios you provided)
Step 1. I dissolve meth in in boiling water and stir till it is all dissolved. (Yes i add all the water in 1 time)

Step 2. In a separate pan i heat aceton to around 50 degrees celsius and add to the meth/water mixture.

Step 3. Stir and let temprature rise to 52-55 max till it starts bubbling.

Step 4. I trow everyting through a filter, cover with aluminum and cling film and leave to rest for 4-6 hours at room temp (about 20 degrees celcius).

Step 5. I put the whole beaker in the fridge for about 12 hours and then freeze for 12 hours more.

Thanks for the fast reply ! I hope we can work this out

Mysticsea3You dissolve meth in boiling water? Why?
I never try that so I can't say or not that s the mistake.
You should try to put your product and acetone together in a recipient like beaker or a bow first (think to crush your meth as fine as possible so the process will be faster) and heat the meth/acetone solution just above the boiling point of acetone which should be at 55-56°C.
Then put your water ( distillated water should be use there because we are doing nothing else that a purification by recristallisation..)
But adding water is for example 7 - 8 ml first then stirr and wait the temperature to reach 53-55°C again so you can add dropwise water until nearly any of the cristal meth is dissoluted.
If you add more water than necessary, the product will be lost.

JimMoriSon27When i started i followed the recipe exactly, but i had a hard time dissolving the meth while it was mixed with aceton.

And when i had finally dissolved the meth it took me so long that alot of aceton had evaporated.

So i used the method i described and had succes one time, but keep failing after that so i will switch back to your advice.

Did you ever had a hard time to dissolve your meth ? And if alot of aceton evaporate what do you do ?

 

[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.
