Stability

1. Chemical properties: The chemical properties of ethyl benzoate are relatively stable and hydrolyze in the presence of caustic alkali to produce benzoic acid and ethanol. When heated to 305°C in the sealed tube, it partially decomposes. It decomposes under electric spark to produce acetylene, hydrogen, carbon monoxide, carbon dioxide and a small amount of methane. In the presence of thorium oxide, it is heated to 400°C to generate benzoic acid and ethylene. Ethyl benzoate and sodium ethoxide are relatively stable when heated to 120°C. But it decomposes into sodium benzoate and ether at 160°C. Ethyl benzoate reacts with chlorine at 200°C to obtain benzoyl chloride and a small amount of acetyl chloride. It is heated to 170～270℃ with bromine to generate benzoic acid and vinyl bromide. It reacts with phosphorus pentachloride at 140°C to produce ethyl chloride and benzoyl chloride.

2. When ethyl benzoate and nitric acid undergo nitration reaction at room temperature, ethyl 3-nitrobenzoate and ethyl 2- or 4-nitrobenzoate are produced in a ratio of 2:1. Ethyl benzoate reacts with lithium aluminum hydride in an ether solution to generate benzyl alcohol. When heated together with ammonia in the presence of alumina or thorium oxide at about 500°C, benzonitrile and ethylene are formed. It reacts with ammonia at 200°C to generate benzamide. Ethyl benzoate can form crystalline complexes with various metal salts, tin chloride, aluminum trichloride, titanium chloride, magnesium iodide, antimony pentachloride, etc. Most of these crystalline complexes are unstable , Easy to decompose in the air.

3. Exist in flue-cured tobacco leaves.

4. Naturally found in peach, pineapple and black tea.
