It was aimed at me, the edited post, someone said they just couldn't help themselves but not be arsed, more or less.
The 'phenidates are esters, don't forget, so they are among the more polar of polar salts, so may well be soluble in alcohols, especially MeOH and EtOH. Not sure about acetone, acetone is polar but then again meth is very, very slightly soluble as the hydrochloride in acetone, although considerably less so than it is soluble in H2O as the freebase. I'm not sure about acetone solubility of the ritalinic acid esters
As for doing a re-X, how much do you have? whether or not its worth recrystallizing depends on quantity.
If you have a decent amount then it might be. I'd do at least a paper chromatography to determine impurities, if not qualitatively, then in a relative quantitative manner (I.e amount of impurities relative to the drug, also number of impurities)
Something I find really useful in cleaning things on a small scale, when working with grams or less to a few g when doing recrystallizations, is to have some borosilicate glass beakers in sizes ranging from 5ml up to 25ml in 5ml increments; plus a few 50ml beakers for holding solvents which are in use at the time and dispensing smaller measures from.
Also, if you know WHAT the impurities are then you could make use of a dual-solvent recrystallization.
(edit-the post above this was typed as I posted).
One thing however, if you can, then use pentane or heptane, or isohexane, rather than mixed hexanes or n-hexane. This is because n-hexane, unlike any of the other isomers of hexane, forms a neurotoxic metabolite, 2,5-hexanedione, that ends up causing a crosslinking of lysine residues in nerve axons, fucking up axonal transport. n-hexane is atypically toxic for a saturated aliphatic hydrocarbon, and where alternatives exist it is better to use one. Also pentane has the advantage that its really quite low-boiling, and can be stripped away quickly.
