Any thoughts on your hexamethylenetetramine procedure compared to the nitromethane reduction?
The hexamine method I posted times ago is not invented by me but it is the adaption of Hexamine on a patent of the IG Farben using formaldehyde.
The patent was referenced by Org.Syn. thats how I discovered it.
The method is simple but timeconsuming. Very timeconsuming IIRC.
The iron reduction of nitromethane to methylamine is comparable quick and results are good to excellent.
Anybody having access to nitromethane and owning a decent overhead stirrrer is better off with the iron reduction. In special when scaling up is an option/necessity and time pressing.
It mostly depends on what one has available I would say as best would be to have a big bottle full of Methylamine-gas and thats it.
But if you are in any hurry and free to choose then nitro is the way to go. Hexamine is still better then having to use nitro in methylalcohol as this azeotrope is a pest taking out most of the fun and advantages.
Pick your poison.
@sw0lepapi420: Cast iron filings is what is used traditionally in the Bechamp process and all offsprings, tendency shifting to catalytic/hydrogen reduced iron powder albeit I believe thats more to the benefit of chem suppliers then the reaction (exceptions exist).
But STEEL wool and heavy gauge sheets of what I guess is mild steel, thats rather daring in my eyes and as long I dont see one, better more references from literature or acccounts of somehow respected members of the community I regard this as utter bullshit, low yields if any at all and a parade of byproducts spurned by what makes steel different from iron.
And completely superfluous for iron of good quality and purity can be bought for asscheap by anyone, by the ton in all screenings one might imagine.
So there is no point in the suggestion except mischief or intellectual underachievement count.
