Recristallization of methamphetamine

[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 !

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?

JimMoriSon27Yes 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 ?
