Synthesis
- Cold medicine tablets that contain pseudoepherine are mixed with a solvent and the solution is exposed to low temperature to separate and remove the dormant material of the tablet
- The pure pseudoepherine is mixed with red phosphorus and hydriodic acid
- Red phosphorus is filtered out and remaining acid is neutralized by adding highly basic lye (highly soluble) solution
- A substance that by law cannot be published by name is added which will bind to the methamphetamine, and the liquid meth is drained out.
- Hydrogen chloride gas is bubbled through the liquid meth, transforming it into crystalline hydrochloride salt.
