What is ETHYL 3-PHENYLGLYCIDATE?
Chemical properties
pale yellow liquid
Chemical properties
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.
Chemical properties
Ethyl 3-phenylglycidate has a strong, fruity odor suggestive of strawberry with a corresponding sweet flavor.
Occurrence
Apparently has not been reported to occur in nature.
The Uses of ETHYL 3-PHENYLGLYCIDATE
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.
Preparation
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.

General Description
Clear pale yellow or yellow liquid.
Air & Water Reactions
Slightly water soluble.
Reactivity Profile
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.
Fire Hazard
ETHYL 3-PHENYLGLYCIDATE is probably combustible.
Flammability and Explosibility
Non flammable
Safety Profile
Moderately toxic by ingestion. Mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS.
