実験手順

Resorcinol, excess formaldehyde, and sodium sulphate were dissolved in water and heated with stirring on a water bath. As soon as the solution became cloudy, the reaction was terminated by the addition of a large volume of cold water. The precipitate was filtered off, washed with water, and dried at room temperature.
