  • Melamine based mannich-compounds and a process for obtaining the same
    Patent number: 8802848
    Abstract: The present invention relates to Melamine based Mannich compounds of the general formulae (1)-(12) and a process for synthesizing melamine based Mannich-products comprising the steps of a) reacting at least one substituted melamine with at least one aldehyde, in particular formaldehyde, under basic conditions to form at least one OH-containing compound, b) reacting the at least one OH-containing compound in the presence of a catalyst to form at least one mannich-base, c1) reacting the at least one mannich-base with at least one enol-forming carbonyl compound, or c2) reacting the at least one mannich-base with at least one aromatic compound, and d) working up the reaction mixture. The invention relates further to precondensates obtainable from these products.
