実験手順

A mixture of 3-trifluoromethylphenylacetic acid (150.0 g), n-octanol (130.0 g), p-toluenesulphonic acid (9.5 g) and benzene (800 ml) is refluxed for 7 hours with a Dean-Stark separator. The solution is washed with a 10% aqueous solution of sodium carbonate (3×500 ml) and with water (3×500 ml). After drying over magnesium sulphate, the solvent is evaporated in vacuo. The residue is distilled (95°-97°/2·10-2Torr) to yield n-octyl 3-trifluoromethylphenylacetate.
