yeah im actually the person everyone goes to for
drug info
this is the other better but harder extraction
This is an extraction tute for Australian users, from cough syrup, however it can be adjusted simply by working out how much DXM is in your syrup. If you have a different source, the same principle can be used, simply work it out yourself.
Reactants:
* 600ml Robitussin DX
* 900ml Ammonium Hydroxide solution
* 300ml Volatile non-polar solvent e.g xylene, toluene, ether
* 50g Citric Acid
* Distilled Water
* Empty gelcaps
* Icing Sugar
* Dextrin or Lactose powder
* Table Salt
Equipment:
* 2000ml solution bottles (sealable)
* Seperatory funnel
* Electric hotplate
* General labware (graduated cylinder, beakers etc.)
* Mortar and Pestle
* OPTIONAL Vacuum evaporation rig
Concept:
Adding ammonia to DXM HBr converts it to freebase. Freebase is nonpolar and will dissolve in nonpolar solvent, in this case preferably xylene (for availability). Solvent is immiscible with water, so physically separate the layers. Acidify the nonpolar solvent which contains the freebase. The DXM converts back into the
acid salt DXM Citrate. The hydrogen ion gradient just sucks the DXM across the solvent-water interface! Poetry in science! Solvent layer is seperated from citrate/water solution and discarded, and the DXM is now
acid salt in the water. Remaining solvent can be driven off by gentle heating. Remainder is DXM Citrate in water solution, which is then concentrated and moderated with a binder, coloured and placed in gelcaps.
Procedure:
Note: First, prepare a solution of citric
acid in 600ml distilled water and a few drops of food dye.
1. Add 600ml (3 bottles) cough syrup to 2L solution bottle.
2. Add 900ml ammonium hydroxide solution
3. Shake it like a polaroid picture.
4. Pour into second solution bottle.
5. Add solvent and NaCl.
6. Again with the shaking!
7. Pour the mixture into seperatory funnel.
8. Stand at least 30 mins.
9. Drain the heavier water/ammonia/salt layer. Will be pink, or whichever colour your syrup was. Wash with extra solvent twice more, seperate solvent and recombine with 1st wash.
10. Discard water layer, add equal volume water to solvent and seperate again. Do this about four times.
11. Add citric
acid solution.
12. Really shake the hell out of it, about 5 minutes hard
13. It takes a few minutes to separate. Wait. If you see froth or soapy sort of layer, wait for it to seperate out as well.
14. Drain DXM citrate solution
15. Gently heat the citrate solution in a pyrex beaker for a few minutes to drive off any remaining solvent. NO OPEN FLAMES!!!
16. Bring the solution to 80*C, so water is steaming nicely, DO NOT EXCEED or you run the risk of denaturing your DXM and destroying all this work. Vacuum evaporation can be used, and is exteremely effective.
17. Maintain temperature until you are left with either a thick syrup or a very small volume of water and precipitated xtals. This will take a while, but it can be done in small amounts. Do not evaporate by sunlight, as protracted UV exposure could destroy the DXM
18. Weigh final mass.
19. Measure out one capsule full of sugar and dextrin, or lactose (per 500mg of DXM citrate) into a mortar or watch glass
19. Add a drop of your chosen food coloring and the concentrated syrup of citrate.
20. Mix until it is all dissolved, and place in a dessicator for 12 Hours.
21. Collect powder with a razorblade or five-cent piece
22. Pestle-grind the powder and divide into individual 500mg doses (assume 5% loss from extraction)
23. Seal in gelcaps, store in airtight browned glass container with silica gel.
