Ethyl benzoate Usage And Synthesis
Description | Ethyl benzoate, C9H10O2, is the ester formed by the condensation of benzoic acid and ethanol. It is a colorless liquid that is almost insoluble in water, but miscible with most organic solvents. |
Chemical Properties | Ethyl benzoate has a somewhat fruity odor similar to ylang-ylang, but milder than methyl benzoate |
Chemical Properties | colourless liquid with an aromatic odour |
Uses | Ethyl Benzoate acts as an aroma and flavour compound due to the volatile ester group in its structure. |
Uses | In perfumery under the name Essence de Niobe; in manufacture of Peau d'Espagne; artificial fruit essence. |
Preparation | By esterification of ethyl alcohol and benzoic acid in the presence of anhydrous aluminum sulfate and a trace of sulfuric acid; by transesterification of methyl benzoate with ethanol in the presence of potassium ethylate |
Aroma threshold values | Detection: 100 ppb; recognition: 150 ppb |
Taste threshold values | Taste characteristics at 30 ppm: sweet, medicinal, green, minty, fruity, birch beer and wintergreen-like. |
Safety Profile | Moderately toxic by ingestion. Mildly toxic by skin contact. A skin and eye irritant. Combustible liquid when exposed to heat or flame; can react with oxidizing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS |
