Latest Patents

Lelgemann holds a patent for the preparation of (2-hydroxyethyl)-melamines and their use as modifiers in N,N',N'-tris-(2-hydroxyethyl)-melamine. This process involves reacting melamine with ethanolamine in the presence of an acidic catalyst. The reaction is conducted at temperatures ranging from 120°C to 250°C, utilizing an excess of ethanolamine. The molar ratio of free ethanolamine to the sum of free and converted melamine must remain above 4:1 throughout the reaction. The resulting (2-hydroxyethyl)-melamines serve as effective modifiers in the preparation of aminoplast resins suitable for laminating surfaces.
