Phenyl salicylate, or salol, is the organic compound with the formula C 6 H 5 O 2 C 6 H 4 OH. It is a white solid. ... Heating phenyl salicylate in turn gives ...
Xanthone can be prepared by the heating of phenyl salicylate: [5] Six methods have been reported for synthesizing xanthone derivatives: [6] The Michael-Kostanecki method uses an equimolar mix of a polyphenol and an O-hydroxybenzoic acid, which are heated with a dehydrating agent. The Friedel-Crafts method has a benzophenone intermediate.
Upon heating, salicylic acid converts to phenyl salicylate: ... Further heating gives xanthone. [8] Salicylic acid as its conjugate base is a chelating agent, with an ...
The Kolbe–Schmitt reaction or Kolbe process (named after Hermann Kolbe and Rudolf Schmitt) is a carboxylation chemical reaction that proceeds by treating phenol with sodium hydroxide to form sodium phenoxide, [1] then heating sodium phenoxide with carbon dioxide under pressure (100 atm, 125 °C), then treating the product with sulfuric acid.
Bismuth salts were in use in Europe by the late 1700s. The combination of bismuth subsalicylate and zinc salts for astringency with salol (phenyl salicylate) appears to have begun in the US in the early 20th century as a remedy for life-threatening diarrhea in infants with cholera.
The same effect can be achieved by adding copious amounts of sodium salicylate or other bases. Heating a glow stick also causes the reaction to proceed faster and the glow stick to glow more brightly for a brief period. Cooling a glow stick slows the reaction a small amount and causes it to last longer, but the light is dimmer.

Methyl salicylate (oil of wintergreen or wintergreen oil) is an organic compound with the formula C 8 H 8 O 3.It is the methyl ester of salicylic acid.It is a colorless, viscous liquid with a sweet, fruity odor reminiscent of root beer (in which it is used as a flavoring), [4] but often associatively called "minty", as it is an ingredient in mint candies.
