What is Ethyl Phenylacetate?
Ethyl Phenylacetate, also known as ethyl phenylacetic ester, is an ester compound derived from phenylacetic acid and ethanol. Its chemical formula is C9H10O2, and it is characterized by a sweet, floral aroma reminiscent of jasmine and other floral scents.
Chemical Structure and Properties
- Molecular Formula: C9H10O2
- Molecular Weight: 150.17 g/mol
- Appearance: Colorless to pale yellow liquid
- Odor: Sweet, floral, resembling jasmine or fruity fragrances
- Boiling Point: Approximately 245°C
- Solubility: Slightly soluble in water; soluble in organic solvents like ethanol, ethyl acetate, and chloroform
The chemical structure consists of a phenyl group attached to a two-carbon chain ending with an ester functional group, which imparts its characteristic aroma and chemical reactivity.
Production Methods of Ethyl Phenylacetate
The synthesis of Ethyl Phenylacetate typically involves esterification reactions, where phenylacetic acid reacts with ethanol in the presence of an acid catalyst such as sulfuric acid. The process can be summarized as:
