Conditions

Temperature
52.5 °C

Procedure

200 g of melamine (1.59 mol) were added to 660 g of a 60% aqueous solution of dimethoxyethanal (3.81 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).
