How best to go about working up some 'phet. Whether to basify the solution (it's in glacial acetic acid) or add isopropanol, because of the massive quantities of salts that would be created upon basing, since the solvent/rxn media is pure acetic acid, adding caustic, carbonate etc. would create huge amounts of sodium acetate. Could be a nuisance, on the other hand it could be useful, since its possible to use isopropyl alcohol to 'salt out' substrates from solvents by taking advantage of osmotic pressure and in say, the case of a water solution, adding a ton of salt to drive whatever it is dissolved in solution out of the concentrated brine resulting, and into the isopropanol.
On the other hand, you can't just gas isopropanol (gassing=term for bubbling in hydrogen chloride [usually] gas and have the product precipitate out. On yet another, not sure if pulling with dichloromethane or toluene, naphtha etc. will pick up the nonpolar fraction (freebase 'phet) with this much salt (would be sodium acetate+iron salts)
