Whilst theres nothing inherently wrong with desomorphine, like mentioned, the drug..and I use the term pretty loosely, is a nasty toxic slop, IIRC the main idea is RP/I reduction of alpha-chlorocodide, created from codeine using thionyl chloride (from batteries probably, since I cannot for the life of me, imagine any other over the counter source, sure as shit its not a street junkie-level synthesis, I've tried myself, and in the end thought fuck that, no thanks, and just buy it from chemical suppliers instead, thought to
save a few quid doing it from scratch but its a lot more difficult than it looks at first glance. I doubt even in russia they sell the stuff in something like a pharmacy, since it has absolutely no medical uses at all. The reaction is not a clean one to begin with. HI/phos reduction is a sledgehammer of an approach in most cases. But from what I've heard, those poor russki bastards are just cooking it up, presumably..surely...hydrolysing the thionyl chloride, possibly neutralizing PH etc and shooting up the crude product.
But gods, theres a nasty bunch of shite in the result. You couldn't pay me to take it by mouth, let alone fucking shoot it up.
I don't even much like the idea of using meth cooked with phosphorus/iodine. Not sure sure about phos acid cooks or hypo cooks. The talk of bisulfite/HCl intrigues me, but of the well known methods, birching is at least cleaner as long as the Li salts are washed out. The only other 'ingredient' being anhydrous ammonia, a gas at RT, cannot of course hang about in the finished product in the case of the birch-B (the benckeser modification being more commonly used than the birch, as to most cooks lithium is more available than sodium, which if you cannot buy, one would have to fuck about with molten salt electrolysis. And its quite finicky if the easy go-to low-MP sodium compound, caustic soda is used, as theres a real fine line between getting it hot enough to melt if a eutectic salt mixture isn't used, and getting it a bit too hot, if that happens the problem isn't that its dangerous, its that the sodium dissolves back into the melt forming a funky blue-grey solid, mostly NaOH, but with dissolved metallic Na in it, as it fizzes, pops and sparks if a chunk of this material is tossed into water.
