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. [5]

It is synthesized by heating salicylic acid with phenol in the presence of phosphoryl chloride. [4] It also arises from heating salicylic acid: [5] 2 HOC 6 H 4 CO 2 H → C 6 H 5 O 2 C 6 H 4 OH + CO 2 + H 2 O. The conversion entails dehydration and decarboxylation. Heating phenyl salicylate in turn gives xanthone. [6] [3]
Salicylaldehyde is produced by condensation of phenol with formaldehyde to give hydroxybenzyl alcohol, which is oxidized to the aldehyde. [4] Salicylaldehydes in general are prepared by ortho-selective formylation reactions from the corresponding phenol, for instance by the Duff reaction, Reimer–Tiemann reaction, or by treatment with paraformaldehyde in the presence of magnesium chloride and ...
Benzyl salicylate is a salicylic acid benzyl ester, a chemical compound most frequently used in cosmetics as a fragrance additive or UV light absorber.It appears as an almost colorless liquid with a mild odor described as "very faint, sweet-floral, slightly balsamic" by some, while others smell nothing at all.
Sodium salicylate 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 by refluxing methyl salicylate ( wintergreen oil) with an excess of sodium hydroxide .
