実験手順
2-Hydroxyimino-N-(2-nitro-phenyl)-acetamide (15 g, 72 mmol) was carefully added in small portions to a stirred solution of preheated (90° C.) conc. sulphuric acid (45 mL) over a period of 30 min and the resulting mixture was stirred for another 2 h at the same temperature. It was then cooled to room temperature, poured into crushed ice, the precipitated products was collected by filtrations. The collected precipitated products were washed with water and dried in a vacuum oven to get a brick red colour powder.
