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