✦ Synopsis

Some results are presented on the studies of reactive solvents for melamine obtained from acetone and formaldehyde in the presence of potassium bicarbonate or triethylamine as catalysts. The chemical structure of the solvents, as well as their ability to dissolve melamine, have been determined. The mechanism of melamine dissolution in the reactive solvents has been analyzed by using the 1 H-NMR technique.

## Abstract Reactive solvents of melamine were prepared from methyl ethyl ketone and formaldehyde in the presence of the catalyst triethylamine. The solubility of melamine in the resulting solvents was determined, and the mechanism of dissolution was explained with ^1^H‐NMR and IR spectroscopy. Pre
