Procedure

Pyrogallol (200 g) was dissolved in 1.4 kg of acetone, and 20 g of phosphorus oxychloride was added to the solution obtained. The resulting mixture was allowed to stand at room temperature overnight. The mixture was then added dropwise to water under stirring. The sediment formed was filtered off, dissolved in a small amount of acetone, and the acetone solution thus obtained was poured into a plenty amount of water. The sediment formed in the water was filtered off and dried to give a pyrogallol-acetone condensate. The melting point was measured to be 200°-210° C.
