Reaction Steps

To an acetone solution containing 200 g of pyrogallol in 1.4 kg of acetone was added 20 g of phosphorus oxychloride, and the resulting mixture was left to stand overnight at room temperature. Thereafter, the mixture was added dropwise to water with stirring, then the resulting precipitate was filtered off and dissolved in a small amount of acetone. The acetone solution thus obtained was poured into a large amount of water, and the resulting precipitate was filtered off and dried, to give a pyrogallol-acetone condensate. The melting point of the condensate was measured to be 200°-210° C.
