OccurrenceHas apparently not been reported to occur in nature.

VerwendenEthyl Maltol is a flavoring agent that is a white, crystalline powder. it has a unique odor and a sweet taste that resembles fruit. the melt- ing point is 90°c. it is sparingly soluble in water and propylene gly- col and soluble in alcohol and chloroform. it is obtained by chemical synthesis.

Darstellung · 1 Eintrag

synthetischeSeveral syntheses have been developed for its preparation. In a one-pot process, for example, -ethylfurfuryl alcohol is treated with halogen to give 4-halo- 6-hydroxy-2-ethyl-2H-pyran-3(6H)-one, which need not be isolated and can be converted to ethylmaltol by aqueous hydrolysis.
