Chemische Eigenschaften
Ethyl 3-phenylglycidate has a strong, fruity odor suggestive of strawberry with a corresponding sweet flavor.
Chemische Eigenschaften
Ethyl 3-Phenylglycidate is a colorless liquid with a strawberry-like odor.
It is prepared by treating ethyl cinnamatewith peracetic acid or by condensation of benzaldehyde with ethyl chloroacetate (in the aforementioned Darzens reaction, R == H).Theglycidate is used as a long-lasting fragrancematerial for creating harmonic, fruity notes in household and fine fragrances.
Occurrence
Apparently has not been reported to occur in nature.
Verwenden
Ethyl 3-Phenyloxirane-2-carboxylate is used in preparation method of early-strength viscosity-breaking Polycarboxylate water reducer containing three viscosity-breaking group and used as concrete additive.
synthetische
Usually prepared by the reaction of benzaldehyde and the ethyl ester of monochloracetic acid in the presence of an alkaline condensing agent; by reacting the silver salt of phenyl glycidic acid with ethyl iodide.
Definition
ChEBI: Ethyl phenylglycidate is an epoxide and a carboxylic acid.
Aroma threshold values
Detection: 8.5 ppm
Taste threshold values
Taste characteristics at 30 ppm: sweet, fruity and berry with dried fruit and floral nuance.

Allgemeine Beschreibung
Clear pale yellow or yellow liquid.
Air & Water Reaktionen
Slightly water soluble.
Reaktivität anzeigen
Epoxides are highly reactive. They polymerize in the presence of catalysts or when heated. These polymerization reactions can be violent. Compounds in this group react with acids, bases, and oxidizing and reducing agents. They react, possibly violently with water in the presence of acid and other catalysts.
Brandgefahr
ETHYL 3-PHENYLGLYCIDATE is probably combustible.
Flammability and Explosibility
Non flammable
Sicherheitsprofil
Moderately toxic by ingestion. Mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS.
