Synthesis of 1-nitroso-2-naphthol

Preparation of 1-nitroso-2-naphthol

Preparation of 1-nitroso-2-naphthol

Preparation of 1-nitroso-2-naphthol

10 g 2-naphhol are dissolved in 2.8 g sodium hydroxide in 100 ml water and made up to 200 ml with water. 5 g sodium nitrite dissolved in a little water are carefully added. The mixture is cooled by the addition of 100 g ice, and 140 ml 10% sulphuric acid are slowly run in with constant stirring, the temperature being kept below 5° C. The 1-nitroso-2-naphthol separates as a pale yellow precipitate. It is allowed to stand for 2 hours, filtered, and washed with water until the washings are only slightly acid. ether. Yield almost theoretical, red needle, m.p. 106-108 °C (dec.).
