Preventing Anhydrous Ammonia From Being Used To Make Methamphetamine
This patent precisely details a method of inhibiting or preventing the use of anhydrous ammonia as a solvent in a dissolving metal reduction process (the most popular method of making Methamphetamine by amateur chemists).
It comprises adding to anhydrous ammonia a chemical reagent which is capable of scavenging solvated electrons generated when alkali or alkaline earth metal is dissolved in the anhydrous ammonia, the chemical reagent being added to the anhydrous ammonia such that when alkali metal is dissolved in the anhydrous ammonia containing the chemical reagent and thereafter ephedrine, pseudo ephedrine or combination thereof is introduced to the anhydrous ammonia to produce a reaction product, the methamphetamine, yield in the reaction product is below 50 %, preferably below 10 %, and more preferably below 1 %.
Although it would be impossible to completely prevent the use of anhydrous ammonia to make meth, this process greatly increases the level of difficulty, time, equipment, and supplies necessary to synthesize methamphetamine by the dissolving metal reduction method.
Because the average methamphetamine producer has relatively low chemistry skills, increasing the level of difficulty is expected to significantly decrease the number of individuals capable of conducting the procedure.
Additionally, by increasing the time, equipment, and supplies required for the synthesis, the risk of detection of the clandestine laboratory will increase as well.
From the Introduction:
In this paper, we report the status of our investigation into the feasibility of introducing a chemical agent into agricultural grade anhydrous ammonia that will render the ammonia useless for methamphetamine synthesis.
Our goal is to provide a means to reduce the number, ease, and stealth that clandestine methamphetamine laboratories using the dissolving metal, or Nazi, synthetic method currently enjoy.
We have conducted investigations of additives that span the broad classes of organic, inorganic, and organometallic reagents. We have identified numerous compounds and classes of compounds that effectively inhibit methamphetamine synthesis. Feasibility evaluations of these compounds are ongoing.
However, we have identified two candidate reagents that possess properties useful for consideration as additives for anhydrous ammonia. Details of the reactivity of these compounds and issues relating to their application for the inhibition of methamphetamine synthesis will be presented
If you are in possession of Anhydrous Ammonia for lawful purposes, prevent the theft, and use of your product for unlawful purposes using this method.
