Hej allesammen...
Jeg fandt et link til en amfetamin-FAQ på Bluelight i en anden tråd, og der er der en interessant gennemgang af hvordan man kan oprense amfetamin (og evt. mdma el. kokain også??) så det bliver næsten helt rent (ifølge forfatter).
Jeg ville derfor høre nogle af kemigenierne herinde, om de eventuelt kan bekræfte at metoden virker? I så fald må man jo sige at det er væsentligt bedre end den gængse acetonevask, som ofte bliver anbefalet her på boadet.
Her er vejledningen:So the procedure: Put your speed into a flask, beaker or some other container you can heat on a stove (note: use a stove without a naked flame, as these volatile organic chemicals produce explosive vapours). Pour acetone into the container so that the speed is completely submerged in it with a centimetre or 2 of excess liquid and swish it around to dissolve any soluble impurities. Next gently heat the acetone until it boils, and then take it off the heat. Now slowly add (with an eyedropper or pipette) just enough alcohol for all the speed to dissolve - stirring gently until the speed dissolves. If you add too much alcohol you won't get as high a yield as possible so don't add too much. Anything that doesn't dissolve is adulterant and should be separated out by filtration: use 2 coffee filters in a funnel to filter the solution, then cover it so a little air can escape and leave to cool to room temperature. Once it has cooled down you should notice crystals starting to form. Put the container in the fridge, and then the freezer to encourage more crystals to form (i.e., increasing the yield). The slower the solution cools, the larger the dry crystals will be. Once the solution has been freezer cooled, filter the crystals out with some coffee filters, then wash the filtered out solid in the funnel with a few drops of alcohol and allow to dry. Voila, you have pure speed. Save the acetone, it can be reused.
