You have to know some chemistry. Learn some (yes it takes some discipline) or be doomed to fail. So, again, this information is posted for information purposes only. I accept no responsibility for anyone actually using this. If you do you will be subject to state and federal laws and will be subject to fines and/or imprisonment. If you are stupid enough to actually manufacture meth you WILL probably go to prison. This is the 90's. So to make meth from ephedrine- Using l- or pseudo ephedrine place 1000 gms of ephedrine, 250gms of red phosphorus, and 1000ml of hydriotic acid in a suitable round bottom flask. Fit the flask with a reflux condenser and reflux the mixture for 48hrs at 120 degrees C. Add a 10% solution of sodium hydroxide until the Ph is 14. You should get an oil layer and a water layer. Separate the oil layer in a separatory funnel and put it a flask with 3 volumes of water. Rig the flask for distillation and distill the oil water mixture until the oil is mostly gone (except for highly colored globs of oil.) In the reciever flask there should be two layers, an upper oil layer and a lower water layer. Separate the oil layer and mix it with 10% hydrochloric acid until the Ph is 7.6. evaporate the water and it will crystallize into methamphetamine hcl. ------------------------------------------------------- Pacifier Online Data Service Dialup SLIP/PPP User To register: (360) 693-0325 or telnet pods.pacifier.com ------------------------------------------------------- From: loonus@aol.com (Loonus) Subject: CLIC Homepage Methamphetamine Synthesis Date: Sat, 01 Nov 1997 00:00:00 GMT Message-ID: <19971101033400.WAA05094@ladder01.news.aol.com> X-Admin: news@aol.com Organization: AOL http://www.aol.com Newsgroups: alt.drugs.chemistry "We have observed that mixtures containing red phosphorus, iodine and either concentrated HCl or glacial acetic acid do convert ephedrine to methamphetamine; however, when the phosphorus is omitted, methamphetamine is not formed. Ephedrine was reacted with red phosphorus and iodine in refluxing water, varying the ratios of red phosphorus and iodine; when red phosphorus and iodine are in excess of ephedrine in a 1:3.8:7.2 molar ratio (ephedrine:red phosphorus:iodine) methamphetamine is formed and the ephedrine is consumed in 8 hours." Anyone have any thoughts, experience with the typical E-RP-HA when the usually separate step of creating the hydriotic acid is omitted and the three chemicals are just reacted in refluxing water.

Newsgroups: alt.drugs.chemistry Materials: 1. 30ml bottle tincture iodine containing 2% iodine, sodium iodide 2.4%, alcohol 47%, rest H20 2. 5 Sinustop Herbal Decongestant tablets containing 60mg crystaline pseudoephedrine HCl each mixed with some herbal ingrediants. Or 300mg of ephedrine obtained thru some other method. 3. 5 road flares. 4. Bottle of drain cleaner containg conc. H2SO4 5. Bottle white distilled vinegar 6. Red devil Lye containing sodium hydroxide 7. Spray can of brake cleaner containing 1,1,1 trichloroethylene or 1,1,1 trichloroethane ------------ Procedure: A. Purifying pseudoephedrine: 1. Take the 5 decongestant capsules, empty their contents into a small funnel with a coffee filter. Pour 50ml of cold water through the filter, and collect the liquid in a small jar. 2. Add a 1/4tsp of lye to the collected liquid. You should immediately smell the odor of ephedrine. 3. Put the resultant solution in another small jar, and add 50ml of brake cleaner, then close the lid and shake vigorously. Let stand so that the layers seperate. 4. Using a turkey baster, suck up the bottom brake cleaner layer out of the jar and put it into a small bowl. 5. Add 50ml of vinegar and heat the resultant mixure over low heat in a frying pan with 1/2 inch of water. Thus a water bath. Do not use a gas stove, since the brake cleaner vapors will produce toxic phosgene if there is contact with a flame. Instead use a hot plate or electric stove at low heat only. 6. Heat the bowl in the water bath until no more liquid is left. At the bottom will be a solid layer of a pseudoephedrine acetate. B. Preparing the red phosphorus: 1. Scrape the red phosphorus off of the caps of the 5 flares and store for later use. You should get about 0.1g per flare. C. Preparing the iodine/HI solution: 1. Pour the entire bottle of the iodine tincture into a small ceramic bowl. Heat on the above type water bath until no more alcohol is left. Let cool, put in a small polyethylene jar, and add 0.1ml of the H2SO4 drain cleaner. Thats about 1/4inch of liquid in the end of an eye dropper. This converts the sodium iodide to HI. You now have a solution of iodine and HI. 2. Add the red phosphorus, and heat bottle in a water bath until the purple iodine color goes away. D. The reaction: 1. Add the pseudoephedrine acetate to the solution of HI/I and phosphorus, and heat on a water bath for 24 hours. E: Extraction: 1. Cool the reaction solution and add 1/2tsp of lye. Take the solution and perform steps A3-A6. 2. You will end up with methamphetamine acetate that you can scrape from the bowl. Congradulations! You have circumvented all of law enforcement and have greatly contributed to the end of the "drug war".

If methamphetamine looks waxy or oily, it is probably contaminated with the HI salt of meth, an oily by-product of the red-phosphorous/HI reduction of ephedrine--the most prevalent method of clandestine manufacture. The HI salt is soluble in acetone, while the HCL salt is only very slightly soluble. The HI salt could be washed out, basified, and then precipitated with HCl gas to give methamphetmine HCL. When completely dry, methamphetamine HCL is soluble in chloroform, while ephedrine HCL is not. This would provide a convenient method of separation.

Please Comment Date: Fri, 08 Aug 1997 00:00:00 GMT Message-ID: <5se45g$36e$1@netnews.upenn.edu> Organization: University of Pennsylvania Newsgroups: rec.drugs.chemistry,alt.drugs.chemistry Uncle Fester's Secrets of Methamphetamine Manufacture describes a procedure for producing methamphetamine via the reduction of pseudoephedrine or ephedrine with HI and red phosphorus. Fester's reduction uses red phosphorus and iodine to form the HI used in the reaction. This is a well known reaction and has appeared in print in: Skinner, HF "Methamphetamine Synthesis via Hydroidic Acid/ Red Phosphorus Reduction of Ephedrine", Forensic Science International 48 (1990): 123-124 Ephedrine and Psuedoephedrine reduce to methamphetamine; PPA reduces to amphetamine. Instead of making the HI via red phosphorus and iodine, let's consider forming it via DMSO, H2SO4, and NaI or KI. This is an extension of Vogel's Practical Organic Textbook's reaction for making HBr. The same one appeared in Pugsley's Bromosafrole preparation. Accordingly: 334g KI or 300g NaI (2M amount) + 400ml distilled water are mixed and cooled in an ice bath. 180ml H2SO4 (sulfuric acid) is added dropwise so that the temperature stays below 75C. As a side note, DMT or HMPT can be used instead of DMSO. However, for this discussion, DMSO is necessary. Now that the HI is formed from DMSO, the reduction of PPA is continued according to Fester: 150g PPA HCl + 40g Red Phosphorus + 340ml HI (made from DMSO) are mixed together in a 1000ml flat bottom (round bottoms require oil baths for heat). This solution is refluxed for 1 day, at least. Make the solution basic via NaOH (lye) to bring out the free base. Extract out the freebase and convert to the hydrochloride. Normally, PPA reduced with HI will form amphetamine. However, it is rumored that the DMSO will aid in methylenating the PPA. In other words, the PPA is reduced via the HI and as a side reaction is methylenated by the DMSO. This will theoretically yield methamphetamine For further information about DMSO, consult Fieser and Fieser "Reagents in Organic Synthesis." Supposedly, very little of the Iodine dissolves in the DMSO, but a lot of it reacts without the whole mass dissolving first. Could the "extra" DMSO be used to methylenate the PPA? Is this a viable mmethod of producing methamphetamine from PPA? Any thoughts or ideas are greatly appreciated. -- R. Zachary Egendorf "I was one born, long ago.

DO NOT ATTEMPT THIS SYNTHESIS. DO NOT DO ANYTHING ILLEGAL. With that in mind, let's talk about speed syntheses. 1. Red phosphorus and HI. 450ml of 57% HI, 160g of l-ephedrine or d-pseudoephedrine, and 25g of red phosphorus are refluxed for at least 32 hours. The ratio for the HI and the ephedrine are: 2 parts Iodine, 1 part Ephedrine, 1/2 part red phos. The red phos in this ratio is used to synthesize the HI. For example, 320g Iodine:160g Ephedrine:80g red phos. The Iodine is insitu or in dH2O. A flat bottom flask is nestled in an ice bath with stirring and contains 400ml dH2O (Is this correct?) and 320g of Iodine. The red phos is added SLOWLY and a lot of heat is given off. Allow the solution to react for about 20 minutes. Remove the ice bath and place the flask on a heating mantle. Attach a condensor and boil under reflux for about 36 hours. Remove the heating mantle and allow cool water to continue to flow through the condensor for about an hour. Pour the red solution through a series of doubled up coffee filters to remove the red phos for later use. Dilute the solution with an equal volume of distilled water. Prepare a dilute lye solution by dissolving lye pellets (RED DEVIL LYE) in dH2O. Liberate the freebase crank oil by adding the lye solution. The crank oil should float on top of the solution, which should be strongly basic. Extract the crank oil with Toluene. Bubble HCl gas through to form the salt. Wash the crystals with acetone and spread out on a plate to dry. Now this method may produce a somewhat crude product. There may be some unreacted iodoephedrine. This may be rectified by recrystalization. Dissolve the crystals in hot ethyl alcohol and tartaric acid. This will separate the d-isomer of methamphetamine from any impurities. I believe that the theory behind this reaction is that red phosphorus reacts with Iodine to form PI3 - Phosphorus Triiodide. The PI3 and water form phosphorus acid and HI. The HI absorbs the hydrogen atom of the ephedrine. It is dehydrating the benzyl alcohol. The red phosphorus (the 25g in this reaction) acts as a recycler for the HI. Journal Article: Topics in Forensic Science International. Skinner wrote an article detailing this procedure. Sources: Red phosphorus: Grind up some flare caps, boil in dH2O, filter and save the filter cake Iodine: Buy some bottles of Iodine at the drugstore. Either set up a double boiler with a metal plate on top to catch the vapors or dry it with a little sulfuric acid (drain cleaner) Lye: Red Devil Lye at the hardware store Toluene: Hardware Store Tartaric Acid: Cream of Tartar Questions: 1. Phosphorus acid, Phosphoric acid, and Hypophosphoric acid are available commercially. Phosphoric acid is available in the building materials section of Home Depot. How could these be used in the reduction and how would they affect the numbers? 2. This is probably from a bullshit recipe, but could TripleSuperPhosphate be used in place of the red phos catalyst? There was mention of a recipe that used 150 parts Iodine:30 parts TripleSuperPhosphate:20g of Aluminum. The Iodine is not in water, but in phosphoric acid. Could phosphoric acid react with Iodine to form HI? Phosphoric acid contains water. In the Merck, Aluminum is said to react with a dilute acid to evolve into hydrogen. Could the hydrogen that is evolved from the Al react with Iodine? Not having tried this - it would be illegal - I am not sure about what is happening in the reaction. How would the phosphoric acid react with the TripleSuperPhosphate? If this is a valid method of producing HI, could AlI3 be used - Aluminum Iodine? 3. Instead of forming the HI from red phosphorus and iodine, it can be synthesized from DMSO, sulfuric acid, and either Sodium Iodine or Potassium Iodine. In an ice bath with stirring, a 2M amount of NaI or KI is dissolved in 400ml anhydrous DMSO. 180ml of sulfuric acid are added. In theory, this should be anhydrous HI. Now, how would the ratio of 450ml HI + 160g Ephedrine + 25g red phos ratio be adjusted? There is also a rumor that because dimethyl sulfate is a methylating agent, PPA (Dexatrim) can be reduced to methamphetamine instead of benzedrine. I would assume that the PPA would have to be dissolved in the DMSO before the HI is formed. Any thoughts? This was posted out of academic interest only. Do not do anything illegal.

Without careful control, dimethylamphetamine would be a serious problem as an undesired product. Also, there are less toxic and more readily available methods for methylating amines. Given the ready avalability of pseudoephedrine, this step is not needed.
