Now, Making Methamphetamine:
To do the reaction, a 1000 ml round bottom flask is filled with 150 grams of ephedrine. Also added to the flask are 40 grams of red phosphorus and 340 ml of 47% hydroiodic acid. This same acid and red phosphorus mixture can be prepared from adding 150 grams of iodine crystals to 150 grams of red phosphorus in 300 ml of water. This should produce the strong hydroiodic acid solution needed. Exactly how strong the acid needs to be, I can't say . With the ingredients mixed together in the flask, a condenser is attached to the flask, and the mixture is boiled for one day. This length of time is needed for best yields and highest octane numbers on the product. While it is cooking, the mixture is quite red and messy looking from the red phosphorus floating around in it.When one day of boiling under reflux is up, the flask is allowed to cool, then it is diluted with an equal volume of water. Next, the red phosphorus is filtered out. A series of doubled up coffee filters will work to get out all the red phosphorus, but real filter paper is better. The filtered solution should look a golden color. A red color may indicate that all the red phosphorus is not yet out. If so, it is filtered again.
