실험 절차

170 g of melamine (1.35 mol) were added to an aqueous solution made up of 311.6 g of 15% sodium glyoxylate monohydrate (Sigma Aldrich, 0.41 mol) and 495 g of 60% dimethoxyethanal (2.86 mol). This mixture was heated under stirring for 2 h at 50-55° C. while maintaining the pH close to 9-9.5 with adjustment, if necessary, with as much 20% sodium hydroxide as was required (about 7 g).
