Extraction of pseudoephedrine from pharmaceutical (Sudafed) tablets.
Pseudoephedrine was extracted from Sudafed tablets using ethanol, ethanol/methanol (90:10% vol/vol) and methylated spirits. The solvents were chosen with reference to the relevant clandestine literature. For each extraction, one Sudafed tablet was crushed using a mortar and pestle and placed in a beaker. The iron oxide coating was removed by repetitive washing with acetone (10 mL in total) until all of the red colour had disappeared. The acetone was removed by filtration and the residue was allowed to dry. The extracting solvent (15 mL) was added to the beaker, which was then covered with aluminum foil and the sample shaken using mechanical agitation for 15 min. The sample was left to settle for one hour at room temperature, and then filtered using gravity filtration. The solvent was evaporated, and the resultant solid collected.

It sounds like this extraction method may have been developed for exactly the pills you have:
Good luck

Hey ... I'm going to Extract with the "straight to E" Method ... I have to buy Solvents ... but The only one that cause me doubt is this VM&P Naphtha ...in Italy, can't find it ...What Substitute you think could work good ? Turpentine? Kerosene? The diesel I use for my car? The fuel for my lawnmower? I have studied the Safety Data sheets of VM &P Naphta but I found 3-4 differents specific composition info about the % composition of various Alkanes, Cycloalkanes and the length of the carbon chains ... Could you tell me here in Europe/Italy what is the product I have to buy to replace VM&P naphta at Best ???
Varnish makers & painters= VM&P, naptha is just mixed hydrocarbons (alkanes)like pentane hexaxane, hepyane octane and nonane and it is petroleum distillates that boil between 30c and 200c.
Ahoj, proč ztrácíš čas a neseženeš si čistý pseudoefedrin hydrochlorid.Ušetříš vic jak polovinu času.
