Birch reduction of Pseudoephedrine to Methamphetamine by Morph in Oz FOR THE RECORD, THIS INFORMATION IS FOR ENTERTAINMENT PURPOSES ONLY This is the completely factual way that my associates used to reduce the OTC psudafed tablets into Methamphetamine in this country. 8 g suzy which converts to 1. There must always be enough lithium present in the ammonia to reduce the pseudo. This flies in the face of how normal Birch reductions work, on e. My understanding of the birch reduction mechanism (for now assume a messy shake n bake) is basically: Lye, lithium, and ammonia are combined in diethyl ether. A packet of 30s is 30 * 60mg = 1. then a weak acid, usually alcohol, donates a proton and the carbon is happy as its alcohol also leaves as water. NH3, or ammonia, is a gas at room temperature. Birch reduction. 3 g end result minimum. This is a very useful reaction and it is pretty cool to carry out too. It is the organic reduction of aromatic rings in liquid ammonia with sodium, lithium or potassium and an alcohol, such as ethanol and tert-butanol. So we start with benzene and to it we add an alkaline metal like sodium and liquid ammonia and also an alcohol, and the end result is to reduce the benzene ring to form 1, 4-cyclohexadiene. Jan 06, 2016 · In this video, we explore the Birch Reduction by carrying it out on benzene. Aug 14, 2013 · Pseudoephedrine extraction Historically, large scale manufacture of methamphetamine from pseudoephedrine tablets using the Birch or Red Phosphorous reduction reaction starts with an initial extraction and separation of pseudoephedrine HCl from inactive tablet ingredients.

The quantities of reactants listed are based on 60 grams of clean ephedrine freebase and the presence of any contaminants including waxes or fillers will change the quantity of NH3 and Li needed for the reduction to complete effectively. The amount of ammonia present is not important, as long as it is sufficient to dissolve all the Li present. In this video, were going to look at the general mechanism for the Birch reduction. This method is often referred to as the lithium-ammonia reduction method or the Birch reduction method. A photo o Aug 11, 2013 · Assuming all else is equal, most clandestine chemists would choose a pseudoephedrine/ephedrine reduction over reductive amination, because reduction of pseudoephedrine produces the more potent d Reduction of pseudoephedrine to methamphetamine via modified Birch (Benkeser) reaction is done with anhydrous ammonia and lithium, (replacing sodium) under anhydrous (lacking water) conditions.

This 2-1 ratio is EXTREMELY important. A SMALL amount of water is added then vessel is capped to create pressure that is released occasionally to avoid explosions From what little I know, it appears that meth manufacturers just carry out a normal Birch, but for some reason it reduces the OH on pseudoephedrine, without altering the benzene ring. Its easily created using ammonium nitrate and sodium hydroxide. In victorian chemists, it is safe to get 2 packets of 30s per person so a couple of people shopping around for a couple of weeks can slowly get a suitable amount of ephedrine. benzene or toluene, where it is the ring that is reduced. This reaction is quite unlike catalytic hydrogenation, which usually reduces the aromatic ring all the way to a cyclohexane . A SMALL amount of water is added then vessel is capped to create pressure that is released occasionally to avoid explosions what’s your formal chem education history? birch reduction uses sodium but it’s actually really cool look at the wiki. While the hydroxyl group of ephedrine is more reactive than the aromatic ring, excess alkali metal and The article goes to explain in detail how the writer and his associates have reduced pseudo freebase to meth in a birch reaction by dissolving lithium in ammonia adding a preaddition toluene with freebase dissolved in it and then adding solid freebase so meth freebase goes straight into toluene. Therefore the proper molar ratio for reactants is 2Li to 1 pseudo
Some say put the pseudo in fist; some say put the lithium in fist. For example, the reaction of benzoic acid leads to 2,5-cyclohexadienecarboxylic acid, – Pseudoephedrine Hydrochloride is water soluble – Since pseudoephedrine, Red phosphorus and Iodine are all Solid compounds, water is necessary for the reduction to occur. For both the Birch reduction method and the red phosphorus method, manufacturers must isolate the ephedrine or pseudoephedrine from the tablets in which it is obtained, so both methods begin with an extraction step. The ratios are 1 AA battery strip for every 7 grams of Ephedrine or Pseudoephedrine as a salt. , 2005). How to make meth (the Nazi way) Birch reduction of Pseudoephedrine to Methamphetamine The article goes to explain in detail how the writer and his associates have reduced pseudo freebase to meth in a birch reaction by dissolving lithium in ammonia adding a preaddition toluene with freebase dissolved in it and then adding solid freebase so meth freebase goes straight into toluene.
