Procedure

Anthraquinone-2,6-dicarboxylic acid (0.50g) was dissolved in sodium carbonate solution (1 equivalent of sodium carbonate, 0.18g, in water, 100 ml) with warming. As the di-sodium salt did not separate on cooling, the solution was evaporated to approximately 1/3 volume and heavily diluted with ethanol. The solid which separated was filtered off, dried at 100°C. and analysed for the dihydrate. Analysis:
