Procedure

0.4 g of sodium hydroxide dissolved in a minimum quantity of water was added to a suspension of 4.8 g pyridine 2.5-dihydroxybenzenesulphonate dibenzoate in 50 ml of ethanol. The precipitate obtained in the water was recrystallized, and 2.8 g of sodium 2.5-dihydroxybenzenesulphonate dibenzoate were obtained. The infra-red spectrum recorded on a KBr disc, gave maxima at the following frequencies: 1740, 1480, 1465, 1240, 1175, 1060, 1025 and 705 cm-1.
