실험 절차

A mixture of 30 g of tara (about 0.1 mole of bound gallic acid), 120 g (0.95 mole) of n-octanol and 3 g of anhydrous sulfuric acid was heated at 140° C. for 7 hours with continuous removal of the water of reaction, after which the mixture was washed neutral with water and then evaporated down to give the crude n-octyl gallate in the form of an oil. The purity of the product was 65% and the yield was 75%, calculated as pure ester.
