Ethyl benzoate CAS#93-89-0
Fragrance: Ethyl benzoate has a distinctive aroma reminiscent of wintergreen oil and ylang-ylang, making it a popular food and flavor additive.
Versatile Reactions: It is highly reactive, undergoing hydrolysis to produce benzoic acid and ethanol, esterification with alcohols, and reduction to benzyl alcohol.
Chemical Stability: The compound is stable under normal conditions, though it is combustible and incompatible with strong oxidizing agents.
Low Water Solubility: Ethyl benzoate is insoluble in water, enhancing its effectiveness in non-aqueous applications.
Ethyl benzoate is a colorless liquid at ambient temperature and pressure, with a fragrance reminiscent of wintergreen oil and ylang-ylang oil, making it a popular choice as a food and flavor additive. This compound is versatile in chemical reactions, including hydrolysis, where it can be broken down into benzoic acid and ethanol. Typically, this hydrolysis occurs under acidic conditions, such as when sulfuric acid is used as a catalyst to yield benzoic acid and ethanol.
Additionally, ethyl benzoate can undergo esterification reactions, where it reacts with alcohols in the presence of an acid catalyst to form various ester compounds. It is also capable of undergoing reduction, where it can be converted into benzyl alcohol and ethanol through reduction processes.
