Red Phosphorus and Iodine Reduction of Pseudoephedrine to ... - Erowid
1) Iodine (13g), pseudoephedrine (10g), and red Phosphorus (4g). Cut the top off a 2 liter soda bottle and place a 16 oz soda bottle with holes in its bottom in it, use a butane or propane torch to heat the top of the 2 liter until the plastic shrinks down around the top of the 2 liter, this will hold it in place and still allow gas to escape.
Information Brief: Iodine in Methamphetamine Production
Hydriodic acid can be produced by combining iodine crystals with water and some form of phosphorus, including red phosphorus, hypophosphorous acid, or phosphorous acid. In the methamphetamine production process, iodine crystals may be used to prepare hydriodic acid in a separate step or may be introduced directly into the synthesis of the ...
Red phosphorus - Wikipedia
Red phosphorus reacts with bromine and iodine to form phosphorus tribromide [14][15] and phosphorus triiodide. Both are useful as halogenation agents, like replacing the hydroxyl group of alcohols. Phosphorus triiodide can also be used to produce hydroiodic acid after hydrolysis.
Methamphetamine Synthesis Via HI/Red Phosphorous Reduction of ... - Erowid
The HI/red P reduction of ephedrine to methamphetamine involves a cyclic oxidation of the iodide anion to iodine and reduction of iodine back to the anion by the red phosphorus, the latter being converted to phosphorous or phosphoric acids 7,8.
Production - Methamphetamine Drug Threat Assessment
The required hydriodic acid in this variation of the hydriodic acid/red phosphorus method is produced by the reaction of iodine in water with hypophosphorous acid. Known as the hypo method, this method results in a high yield of d-methamphetamine and usually is used only when the producer in unable to acquire red phosphorus, although it can be ...
Ephedrine Reduction with HI/P - Erowid
In a 500 mls round-bottom flask is added 150 mls of glacial acetic acid, 15 grams of red phosphorus, and 33.50 grams of iodine.[NOTE 6] The mixture is allowed to react for 15 - 20 minutes, until all of the iodine has reacted.
The AccuTOF-DART analysis of iodine and red phosphorus is an extremely rapid technique that can easily be included in the forensic identification scheme for these common chemicals,
Solution Synthesis of Iodine-Doped Red Phosphorus …
2017年1月12日 · Here, we report the large-scale synthesis of red phosphorus nanoparticles (RPNPs) with sizes ranging from 100 to 200 nm by reacting PI 3 with ethylene glycol in the presence of cetyltrimethylammonium bromide (CTAB) in ambient environment.
Methamphetamine synthesis via hydriodic acid/red phosphorus reduction ...
1990年12月1日 · The illicit manufacture of methamphetamine from ephedrine via reduction with hydriodic acid and red phosphorus is discussed. The stereochemistry, mechanism, synthetic impurities, and analysis of clandestine methamphetamine samples are addressed.
Methamphetamine Synthesized from Pseudoephedrine
Procedures have been reported using HI alone 13, using molecular iodine and red phosphorus 14 where the HI is formed in situ and the currently popular method for manufacturing illicit methamphetamine by using a mixture of HI and red phosphorus. The role of the phosphorus is to convert the molecular iodine formed in the reaction back to HI.
