Chemische Eigenschaften
Ethyl 3-Methyl-3-phenylglycidate exists as two optically
active pairs of cis- and trans-isomers; each isomer has a characteristic odor
. The commercial product is a racemic mixture of all four isomers and has
a strong, sweetish, strawberry odor. The cis/trans ratio obtained in the Darzens
condensation of acetophenone (R==CH3) and ethyl chloroacetate depends on the
base used in the reaction.
Occurrence
Has apparently not been reported to occur in nature.
Verwenden
Ethyl 3-methyl-3-phenylglycidate is a synthetic flavoring agent that is a glycidic acid ester. It is a colorless to pale yellow liquid with a strong fruit odor suggestive of strawberries. It is unstable to alkali and moderately stable to weak organic acids. It should be stored in glass, tin, or aluminum containers. It is soluble in fixed oils and in propylene glycol. It is used in flavors for strawberry note and has application in candy, beverages, and ice cream at 6–20 ppm. It is also termed aldehyde c-16.
synthetische
By reaction of acetophenone and the ethyl ester of monochloroacetic acid in the presence of an alkaline condensing agent.
Allgemeine Beschreibung
Clear, colorless to yellowish liquid with a strawberry-like odor.
Air & Water Reaktionen
Insoluble in water.
Reaktivität anzeigen
Esters, such as Ethyl 3-methyl-3-phenylglycidate, react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
Brandgefahr
Ethyl 3-methyl-3-phenylglycidate is probably combustible.
Handelsname
Strawberry pure (Givaudan)
Sicherheitsprofil
Mddly toxic by
ingestion. Mutation data reported.
Combustible liquid. When heated to
decomposition it emits acrid smoke and
irritating fumes. See also ALDEHYDES.
