Versuchsvorschrift

10.0 g of 2-hydroxyacetophenone is dissolved in 60 ml of glacial acetic acid. 10.4 ml of nitric acid (specific gravity=1.40) is then added over 2 hours at room temperature. The mixture is stirred for 17 hours, then poured onto ice and the resulting precipitate (containing both the 3- and 5-nitro isomers) collected. The isomers are separated by HPLC to give 4.0 g of 2-hydroxy-3-nitroacetophenone.
