PROCESS FOR THE MANUFACTURE OF PARTIALLY ETHERIFIED METHYLOLMELAMINES

摘要

Process for the manufacture of monomeric methylolmelamines which are partially etherified with aliphatic alcohols having 1 - 2 C atoms and which contain at least 4 moles of formaldehyde per mole of melamine, by reacting melamine, paraformaldehyde and methanol or ethanol in a one-stage reaction, the molar ratio of melamine to formaldehyde to alcohol being 1:5 - 10:6 - 20, in a virtually anhydrous medium, under a nitrogen atmosphere, at a pH value of 7 - 8 and temperatures between 50 and 90.degree.C and with a reaction time of between 3 and 30 hours.
