Is it possible to convert acetylsalicylic acid back to salicylic acid? I have some nice recrystalized acetylsalicylic acid but would like to try the
synthesis of methyl salicylate, which requires salicylic acid and methanol.
Or is there a way to make that esterification work with acetylsalicylic acid and methanol?
Thanks!

If you dissolve ASA in basic aqueous solution and boil it for a while, it should hydrolyze. Acidify to precipitate the acid.

Easy. Mix it with a large exess of water with about 7% hydrochloric acid and reflux for a half hour. Let it crystalize and vacuum filter it (you can
use gravity filtration, but vacuum filtration is way faster and dries it)
