Versuchsvorschrift

Thereafter, a mixture of 33.2 g (0.187 mole) of the thus obtained 2,6-dihydroxynaphthalene, 15.0 g of acetic acid and 44.9 g of acetic anhydride was stirred for 90 min in an oil bath kept at 140° C. After the reaction was over, the reaction mixture was cooled to room temperature and the thus precipitated crystals were collected by filtration, washed with acetic acid and dried to obtain 41.8 g of 2,6-diacetoxynaphthalene of white in color in a yield of 91.7%.
