Procedure

To a solution of 629 g. of 2-ethylresorcinol in 1 l. of dioxane were added 530 g. of benzaldehyde and 30 g. of phosphorus oxychloride as a catalyst. The resulting mixture was stirred at room temperature for 24 hours and thereafter poured into 5 l. of a cold water with stirring to give a pale brown powdery resin.
