Preparation of Ethyl propionate: it can be prepared by ethanol and propanoic acid. Add ethanol and propanoic acid into the reactor at first. Then add calcium chloride into the mixture with stirring. This reaction should reflux for 10 hours by heating and stirring. And then after a series of distillation, washing by sodium carbonate solution, drying and distillation again you can get the desired product.

Uses of Ethyl propionate: it can be used for food flavoring agents. And it can react with ethane-1,2-diol to get propionic acid-(2-hydroxy-ethyl ester) and 1,2-bis-propionyloxy-ethane. This reaction will need catalyst Dowex 50W and solvent octane. The reaction time is 4 hours at reaction temperature of 100 °C. The yield is about 81%.
