Iodine red phosphorus reaction

WebIodine is routinely found at clandestine laboratories producing methamphetamine via the HI/Red Phosphorus method. The iodine is used instead of hydiodic acid. Iodine is also a decomposition product of hydriodic acid. Therefore, personnel entering clandestine laboratories may encounter iodine from off-gassing reaction vessels or storage containers WebAnyone mind sharing a good recipe using the red phosphorus/iodine reduction mechanism. Do a search for "long wet reflux". It takes 24 hours at the minimum, but it's safer, higher-yielding, and higher quality than the alternatives. Being patient enough to let this reaction run its course makes all the difference when it comes to quality.
