実験手順

Formaldehyde (8.85 parts of 37.3 percent solution; 0.11 mole), adjusted to pH 7-8.5, is diluted with water (20 parts). While stirring, 11.8 parts (0.1 mole) of dihydroxyethyleneurea powder are added. The temperature is raised to 55° C., held at 55° C. for 30 minutes, cooled to room temperature, and refrigerated. The sample is recovered as an 80 percent aqueous solution.
