Procedure

To a solution of 550 g. of resorcinol in 1 l. of ethanol were added 530 g. of benzaldehyde and 0.5 ml. of 35% conc. hydrochloric acid as a catalyst. The resulting mixture was heated under reflux for 90 minutes with stirring and, after completion of the reaction, the reaction mixture was poured into 5 l. of a cold water to give a pale brown powdery resin.
