pfed.hcl solubility in ethyl acetate
« on: January 05, 2004, 08:35:00 PM »
in a recent dream, swie was extracting some pfed from some kiddie's nasal decongestant elixir, and mistakenly used a solvent which appeared to be 70% toluene and 25% 'acetates'...

Of course, as one could not have predicted (except by reading the msds of it), after drying the 'solvent' with calcium carbonate and a teaspoon ful of carbon, sat overnight, when it came to bubbling anhydrous HCl through it, no snow... swie was a little disappointed, and cursed itself for not using the xylene it also had... the stuff just clouded up. swie presumed that he had succeeded in transforming the freebase into hcl salt, but that the non water component of the 'solvent' was holding quite a bit of the HCl and the pseudo HCl as well...

And the next thing that swie discovered was that, of course, the ethyl acetate came across somewhat in water washes intended to remove the HCl salts out of the solution... when it came to the bottom of the dish, it was like this honey like consistency (and a yellow colour swie decided must have come from the CaCl somehow, it was not technical grade by any stretch)... and the next neat thing was the crystal formations, it seemed to form these plates, maybe rhombic can't tell cos there wasn't enuf to get sizy crystalls. looked strange, kinda grey in one angle and with bright light through it, one of those things they put on glass doors, with a pattern like zinc on galvanised iron.

swie has slapped itself silly and sworn to only use the xylene in future for extractions intended to be gassed (*wince*)

will this acetate stuff be holding a lot more of the goods than it normally would? the mixture still looks cloudy, although this could be from dissolved HCl
