Generating anhydrous ammonia yourself is extremely dangerous. Do you really like speed this much? Enough to risk your life?
If one was able to get there hands on anhydrous ammonia it would be a hell of a lot easier than fucking around with generating your own. If I did things like that, i would go with the refrigeration grade NH3 if it were available. ::)
Anhydrous Ammonia is also known to the HVAC/R world as
R-717 and you don't need a license but you may need a hazmat certification to purchase it in some locations. SWIM has purchased it for many "tweekers". It has been anhydrous but has had oil in it from poor containment processes
Make P2P instead of annie. Problem solved.
i seriously dont see the point in handling anhydrous ammonia and working with dangerous birch reductions, unless you were obliged to reduce literally kilograms of pseudoephedrine in a short time span!
the HI/P is HI/P if you're a small time cook.
