Sodium salicylate (CAS 54-21-7) is a sodium salt of salicylic acid. It can be prepared from sodium phenolate and carbon dioxide under higher  temperature and pressure. Historically, it has been synthesized from methyl salicylate (found in wintergreen plants or the bark of sweet birch tree) by reacting it with an excess of sodium hydroxide and heating it under reflux.
