The aroma of ethyl acetate is most vivid in younger wines and contributes towards the general perception of "fruitiness" in the wine. The estimated hydrolysis half-life at 25 °C and pH 7 is 2. Hazardous gases produced in ethyl acetate fires include carbon monoxide and carbon dioxide. It has also been prepared from ethylene using an aluminum alkoxide catalyst. CH 3COOCH 2CH 3 + H 2O The reaction can be accelerated by acid catalysis and the equilibrium can be shifted to the right by removal of water. On prolonged storage, materials containing similar functional groups have formed explosive peroxides. Coffee beans and tea leaves are decaffeinated with this solvent. In the laboratory, and usually for illustrative purposes only, ethyl esters are typically hydrolyzed in a two step process starting with a stoichiometric amount of strong base, such as sodium hydroxide. Ethyl acetate has a fruity odor detectable at 10ppm. Sasol in South Africa was said to be investigating such a process in the early 2000s. It is also used in paints as an activator or hardener.
